  1. I think that Will Durant is saying is that we can not know what is going to happen next. the world will always cerprisd us every day. we have to perpar for the worst. we can;t cange the eath the earth cange us. I rellay like that the satemen because I it says that we sould be more careful what we do nect so it won't enfet us later.

  2. i dont think that there are any topics that i am unsure of, but i am unsure of what a ring of fire is and where it comes from. there was a question on the quiz that asked what a ring of fire was and where it came from, i dont know. i think that all of the vocab words we learned were important, but some more than others. like plates, the three types of boundaries there are and what they create, lithosphere and asthenosphere, and also the oceanic and continential plates.

  3. I feel like I understand all of the terms we have covered this week. I didn’t like lab this week though because we could not get our experiment to work. It was frustrating, but I still do think I understand all of the vocab words and such.

  4. This week we are learning about volcano's. I never really realized it but all of the plate boundaries can make a volcano. The hottest volcano's are made from divergent boundaries and those boundaries make hot spots as well. It is all really fascinating and I am looking forward to lab this week.

  5. This week we learned about volcanoes. We learned about why they erupt, where they form, and the different kinds of volcanoes. Off the power point we have had to read it talked about the three types of volcanoes. Shield, which is the widest in size. Cinder Cone, which is the smallest in size. And last the composite, which is the tallest in size.

  6. I wasn't in class the entire week. But in lab we expiremented with and acid and having that mix with water to have access stuff come out. I don't get the ring of fire and what that is from. I know its underwater volcano. I think. I took a quiz and I don't know how I did... I'm just trying to make this seem a little longer..

  7. Everything we learned in class this week was kind of a review from last week. The vocab words I think are the most important are the types of plate boundaries and the layers of the Earth and what each layer is made up of. We also learned this week more about volcanoes and how plate boundaries create them.

  8. This week we are laerning about volcanoes. We already know how they are formed because of the plate boundaries that we just learned and we are learning abot how the elemtal compositon of the plates effect the temperature and other factors of the volcano. In lab this week we did an expirement exampling the tolerance level of humans with seperate gasses that are emitted from volcanoes.

  9. This week we learned about volcanoes and their emissions. Volcanoes usually form at converging and diverging boundaries and can occasionally form at hot spots. When a volcano is about to erupt, certain gases like carbon dioxide are emitted. If these gases become close to the threshold value, which is the amount of carbon dioxide that humans can safely handle, then they will order an evacuation.

  10. This week we learned mainly about volcanoes and where they can form at. In lab we learned about the threshold value and what it means. A threshold value is the amount of something that humans or other living things can tolerate. We learned more in depth about boundaries and hot spots.

  11. This week I learned about volcanoes. I learned that there are three types, shield, cinder cone and , and composite volcanoes. Composite volcanoes are the tallest and the most explosive and also the most dangerous. The cinder cone is the smallest and is usually next to a large volcano. The shield volcano is less explosive. I also learned about magma and lava. Magma is under the ground and lava is above the ground.

  12. This week in lab we mixed baking soda and vinegar and waited for the gas to push the water into the grduated cylinder. The purpose of this lab was to teach us about threshold value and to help us apply that to volcanoes.

    ReplyDelete
  13. This week we finished our studies of the Theory of Plate Tectonics on volcanoes. In lab we imitated an eruption with sodium bicarbonate and acetic acid creating gas and pressure, enough pressure to break the threshold. And our homework for today was to take notes off of a powerpoint to understand more about volcanoes.
    All volcanoes are fueled by magma deep beneath Earth's surface. Magma is a mixture of molten rock, suspended mineral grains and dissolved gases deep beneath Earth's surface. Magma is formed when temperatures are high enough to melt the rocks involved. Lava is magma that has reached the Earth's surface. Volcanic gases is the expansion of gases that bring the magma closer to the surface and drives eruptions. We learned the parts to a volcano, such as the vent, crater, and the magma chamber. Then we read about the ash cloud. Volcanic ash consists of tiny pieces of rock and glass. Falling ash can turn daylight into complete darkness. Tephra is rock fragments thrown into the air during a volcanic eruption. Volcanic bombs are blobs of lava that can harden in the air or hit the ground, flatten then solidify. We learned about three types of volcanoes, shield, cinder cone, and composite. They all differ in size, and how they form. How intense each of the eruptions is changes with the type of volcano as well.

  14. This week in class we talked about threshold value and volcanoes. Volcanoes are much easier to predict than earthquakes. Threshold value isn't just for volcanoes. Lots of things have a threshold value, like medicine, pain, and exertion.

    ReplyDelete
  15. Well what we have discussed in clas was thrshold and volcanoes. Also the difference between volcanoes and earthquakes. With a volcanoe you can predict when it will happen just not an exact date and with earthquakes you cant predict when it will come. Threshold's value has to deal with a lot of stuff like volcanoes, medicine, pain, and ect...

  16. This past week we learned mostly about volcanoes. We learned the gas levels can help us predict when a volcanoe will next erupt. We learned that volcanoes form at plate boundarie and there are three types of volcanoes.Cinder, Sheield and, composite. In lab we immitated the gases the emit from volcanoes. I think the main purpose this week was Threshold Value. threshold Value is how much of something it takes to make something else happen. This concept can be applied to many situations in life. How much radiation it takes to make you sick, how much sun it takes to make you sunburned. Almost everything has a threshlod value.

  17. This week in class, I learned about what isotopes are and the three different kinds of particles that are considered radioactive- Alpha, beta, and gamma particles. I also learned what a subatomic particle is.

  18. This week was a pretty easy week but there are still things I'm not sure of. I don't understand the differences between the three types of volcanoes and I don't understand what the ring of fire is. The review of the atom was pretty important I thought as well as learning about radiation. I thought it was interesting how radiation didn't connect to the eletromagnetic spectrum. I think the most important vocab word was threshold we not only talked about it in lab we discussed it in lecture too.

  19. This week we learned about volcanoes and I understood the lab and the powerpoints but on Wednesday working on that sheet i got really confused and i wasn't sure what all the answers were. Today I really got the isotope symbol notation, I thought it was clear and easy.

  20. This week we learned about threshold values and volcanoes. I wasn't in class on Monday or Wednesday so I am a tad bit confused on volcanoes but I think I will be able to get it in the next week or so. Lab really helped me understand the threshold value a lot easier. In class today we learned about isotopes. There are three different types of particles that are radioactive. Alpha particles are the very weakest made of two protons and two neutrons. Then comes the beta particles that are made of one electron and a little stronger than the alpha particles. The gamma rays have very high energy and are the strongest. That I understood fairly well which was good. So ya!

  21. This week we started to look at volcanoes and how they are attached to the core. Volcanoes are very perdictable because of the gases that are in the the volcanic tubes. This week I understood everything that we studied.

    This week in science we talked a lot about volcanos. We talked about where they are formed, how to predict when they will erupt, and the different kinds of volcanos. Volcanos are formed near converging plate boundaries. Volcanos are easier to predict than earthquakes because they have a threshold value. A threshold value is the limit or last value that is considered safe or in this case before the volcano erupts. The three different types of volcanos are shield, cinder cone, and compostie. Each type is different in size, explosiveness, and how they were formed. Composite volcanos tend to be very explosive and the tallest. Shield volcanos are the least explosive but not the smallest. The cinder cone volcanos are the smallest and intermidiate in explosivness.

  23. This week in science class we learned about volcanoes. We learned what kind there are how much they explode. Also we learned that volcanologists study the amount of gas that comes from a volcanoe to see when they should evacuated an area around the volcano. This is a very intresting process in which they mix gases to create a threshold amount of gas a person can handle.

    ReplyDelete
  24. This week we talked about volcaneos and how they generally work. We talked about a threashold value and what it means. We talked about how gasses cause erruptions and that sciencetists can measure these gas levels to try and detrmine with some accurcecy when and how explosive an erruption will be. We talked about how each type of different plate boundry volcaneo are different from each other.

  25. This week we learned about volcanoes.
    We learned that volcanoes can be at convergent, divergent boundaries and Hot Spots.
    There are 3 types of volcanoes; shield, cinder cone and compostie. We also learned what the threshold value was. I am not unsure of anything we covered this week.

    ReplyDelete
  26. This week when we learned about volcanoes, we learned why geologists study the gases. It is on order to determine how explosive it will be. Volcanoes can occur on convergent and divergent boundaries and on Hot Spots. We learned that when the emmisions get to a certain point that is called the threshold and an evacuation should be oredered. The three types of volcanoes are sheild, cinder cone and composite.

    ReplyDelete
  27. This week we learned about volcanoes and how the reason that they erupt is because the lava is displaced by gases. The reason that there are different volcanoes is because there are different fault lines that release different ammounts of gasses. There are also some volcanoes that are over hot spots which means that they are not on a fault line but they do have a lot of magma build up under them.
    In lab we simulated how the displacement of magma is caused by gas but we used vinigar and baking soda to get the co2 to displace the water causing the water to flow in to a graduated cilinder. A vocab word that we learned this week was threshold and that means: the amount that an object can take before breaking or exploding.

  28. This week we learned about volcanoes. I understand the vocab and am ready to move on to new subjects. Are we going to learn about geothermal energy? I did not like lab this week because we could not get ours to work until we cut the tubing shorter and taped it all together, but I understood the significance of the lab.

    ReplyDelete
  29. This week we had a lab on volcanos, and we actually measured the gas emissions from a model we made in lab. I learned that volcanos have something called a threshold value in which it meant (in my own words) is the limit to where the most amount of anything can be taken up before becoming dangerous. I also learned that the threshold value of a volcano is 150ml of gas (CO2) and we found that in this lab the more amount of the acidic acid and the same amount of sodium bicarbonate that it will increase steadily how the amount of gas generated. I personally didn't know that volcano eruptions couldn't be predicted as where an earthquake can be which i thought was pretty cool.

  30. This week we talked a lot about volcanoes. I learned that the diferent types of volcanoes are more more explosive than others. Another interesting thing i learned was that the atomic mass of an element is acctually an avererage of all of that element.

    ReplyDelete
  31. This week helped confirm and clear up some things that I wasn't quite sure about on volcanoes or the different boundaries. I understand that divergent boundaries create new crust and convergent boundaries create volcanoes. I also learned that there is a threshold for the amount of gas being emmited that you can allow before you have to call an evacuation. This weeks lab was a great demonstration and helped me learn a lot.

    ReplyDelete
  32. This week in lab we learned about volcanoes and what they can do. In lab we combined baking soda and vinegar to push the water through the tube and into a cylinder. It was teaching us about the threshold value. I feel that I understand threshold value but I am still confused on some of the radioactive decay terms that we learned about on friday. I understand where it comes from but I am confused about all of the kinds of it.

  33. This week in class we learned how we can sort of predict vocanoes and cannot at all predict earthquakes. We can predict volcanoes because of the threshold of the CO2 sevels in the volcano. Cities around the volcano should be evacuated when they start to see a big change in the CO2 coming out of the volcano. This weeks lab helped me learn this. GO CANADA!!!

  34. This week in lab we learned alot about volcanoes and the different types. We also learned about the threshhold value of something which can help determine when a volcanoe can errupt. But we can still not predict when earth quakes will happen.

    ReplyDelete
  35. This week I learned that you can generally tell when a volcanoes is about to erupt by taking gases emmited by the volcanoes and measuring what kind of gases they are. Also, I learned that elements don't always hae to have the same number of protons and neutrons, and the ones that don't are called isotopes. They can have more protons than neutrons.

    ReplyDelete
  36. This week in class we learned about the threshold on volcanoes. The lab I thought was confusing until we talked about it class and now I understand it a lot better. A Threshold is the amount of something that causes something else to happen. What I thought was interesting was where else we use thresholds. I now understand that divergent boundaries create new crust and convergent boundaries make volcanoes.

    ReplyDelete
  37. This week we began to learn about volcanoes. I didn't think this week was hard to understand, and I feel like I get everything we learned this week. I thought it was pretty cool how we can predict volcanoes erupting through the gases that they emit.

    ReplyDelete
  38. this wekk we finished learning all about volcanoes and how they work. in lab we demonstrated how a volcanoe works by mixing baking soda and vinegar togetherto produce a gas to push the water up. i dont have any questions so far on volcanoes.

    ReplyDelete
  39. This week in lab we talked about threshold values and how volcanoes are more predictable than earthquakes. Volcanoes have gases that build up inside of them witch makes it either really explosive or not to explosive. Some gases are CO2 SO2 S2 and Na.

    ReplyDelete
  40. This week we learned more about volcanoes and I think that the experiment was not that successful but it was fun because when it did work it looked really cool. I think that I understand most of the vocabulary that. We learned about protons, Isotopes, atomic number, atomic mass, and Radioactivity

  41. THis week in lab we got to mesure the amount of gases releaced from some chemicals, just like a volconoligist does to a real vocano. My readings where a little messed up, but over all i got the concept. This week was over all very efective.

    ReplyDelete
  42. This week, we measured CO2 emmissions from acetic acid and sodium bicarbonate reactions. It taught us about threshold gasses and how they are used by Vulcanologists to determine if a volcano will erupt. We also learned about isotopes.

  43. This week i learned that we measure acids to try and determine how explosive a volcano will be. In lab this week we measured CO2 to represent measuring the acids in a true volcano. Also something i learned is that the temperature of a volcano largly depends on what kind of acids are present and how much of each acid are there. Mainly we learned about the acids in volcanoes.

  44. This week we learned about volcanoes. We learned about the warning signs of a volcano, the types of volcanoes, and how the plate boundaries effect the volcanoes that form on them. In lab we simulated an erupting volcano. The gas we collected from mixing baking soda with vinegar caused water in a flask to be pushed out into a graduated cylinder. This simulates what happens when a real volcano erupts. Scientists can use the amount of gas that is emitted from the volcano to see if the volcano is going to erupt. This is very useful because if scientists have an idea of when a volcano will erupt, they can evacuate people near the volcano. Shield, cinder cone, and composite are the three types of volcanoes. Shield volcanoes are the widest and also the least explosive. They form when layers of lava accumulate from non-explosive eruptions. Cinder cone volcanoes are the smallest and are more explosive than shield volcanoes, but less explosive than composite volcanoes. They are formed when tephra falls back to Earth and piles around the vent. Composite volcanoes are medium in size compared to shield and cinder cone volcanoes and are the most explosive of the three. They form when layers of volcano fragment alternate with lava. 95% of volcanoes occur at convergent and divergent boundaries, while 5% occur on hot spots.

  45. This week we learned about volcanoes. We learned about how they are made, the differences between certain volcanoes, and we also learned that divergent plate volcanoes are different form convergent plate volcanoes.

  46. This week we learned about volcanoes. We learned how they are formed. We also learned that volcanoes release CO2 and the more the volcano releases the more likely it is to erupt. In lab we tested how much CO2 it takes for certain amount water will be transferred from one place to another.

    ReplyDelete
  47. we learned more about threshold values and volcanoes. threshold values are used by scientists to determine when a volcanic eruption is about to occur. we also saw different types of volcanoes (cindercone, shield, composite) and how dangerous these different kinds are.

  48. This week in science i was only here thursday and friday. From those two days i learned what a threshold value is which is the maximum amount of a substance that can be held without causing danger. This weeks lab was probably the funnest lab we've done.We used tubes to capture the water from the gas coming up from the two materials. It made me really understand what a threshold value is. Then on friday we learned more about atomic structures and how to solve for them.

    ReplyDelete
  49. This week in science lab, we studied gas emissions from volcanoes. We imitated these gases by mixting baking soda and vinegar to imitate carbon dioxide. Then, we used the carbon dioxide to move water. Our group learned that if you swirled the beaker with the baking soda in it from the start, the reaction was greater and displaced more water. If you swirled it when the reaction started slowly down, it displaced a little more water and then stopped. This was used to demonstrate the threshold value. In this case, a threshold value was the amoutn of gas that could be tolerate by a human before the human died. Since volcanoes cannot be predicted to the exact moment, evacuations are called when the gas emission get near the threshold value.

  50. This week I learned about volcanoes, what kinds, and how they erupt. The lab really helped me understand how volcanoes erupt, even though my lab didn't work. One vocab word i thought was important was threshold value, which is the amount of gas that a substance can hold before causing danger. There are three different type of volcanoes cindercone, shield, and composite. This week I also learned more about the different plates there are, convergent, divergent, transforming, and I also learned what a hot spot volcano is.

  51. This week, we learned that volcanoes get their energy from the core of the earth. We talked about the amounts of gas released from a volcano and the type of eruption it is going to be. The indicator for an eruption are the amounts of sulfur, hydrogen and oxygen a volcano releases. We also discussed how it is easier to predict a volcano then it is to predict an earthquake because of the gasses released in a volcano. We talked about hot spots, divergent and convergent boundaries , in relation to plate boundaries. We did a worksheet for homework over a PowerPoint, and learned some excellent vocabulary about volcanoes.

  54. this week we learned about volcanoes and where they can occur. I learned the the can occur at any plate boundary but mostly and divergent and convergent boundaries. I learned about the three different types of volcanoes; shield, cinder cone and composite and how they were formed. I also learned about threshold values and how much something can take before something happens. I understand everything this week and lab was fun.

    ReplyDelete
  55. I understand all of the terms we went over this week. I learned that different plate boundaries cause different types of valcones, such as higher temps, different hydrogen, carbon, and sulfur levels. This weeks lab was cool but our first attempt was over the threshold so we got really confused.

    ReplyDelete
  56. This week we learned about threshold value, isotopes, and where volcanoes form, along with the different types of volcanoes, as well.

    Two atoms walk into a bar, they sit down and one says "I think I've lost an electron." the other one says "are you sure?" to which the first one replies "Im positive."

  57. This past week we learned about volcanoes. We learned that they form from convergent boundaries. Our lab demonstrated how all volcanoes have a threshold value. Volcanoes can be very harrmful and destructive, but they can also be useful when they form new land like Hawaii or ocean ridges.

    ReplyDelete
  58. This week we learned about the correct symbol notation for expressing different isotopes. I learned that an alpha partical is very weak, a beta partical is stronger and a gamma ray is very energetic which these are the 3 different forms of emitted radiation. i also learned that volcanos are made from convergent boundaries and i learned about threshold values.

  59. This week we learned about volcanos. We learned what an isotopes is. We also learned about how to know what what different isotopes we are talking about, by saying the atomic number and the symobl and the name of the isotope.

  60. studying volcanoes this week made me remember talking about them in eighth grade and how scientists know a volcanoe is getting ready to erupt. The tectonic plates become more active causing earth quakes.

  61. this week we learned about isotopes and volcanoes and what a threshold value is. at first i was kind of confused about what a threshold was but when i heard some examples of it, it made sense.

  62. This week was the craziest week IV had so far this school year. We learn about volcanoes this week and the different kinds and how there formed, why the explode, how they explode, and how to figure out when they will explode. In lab we tried to make enough gas to push the water up a tube and in to a graduated cylinder but we thought both tubes had to be in the water so I pushed the L shaped tube into the water not think about it breaking... and it did so my grope didn’t really get any water into the cylinder but it was a kind of fun week. :)

  63. This week we learned everything about volcanoes. It was a productive week except for lab. in lab we couldnt get anything to work. we had a perfect setup but nothing would work.

    ReplyDelete
  64. This week was interesting. My memory was refreshed on how volcanoes work, and I learned that there can be somewhat of a prediction to when a volcano might erupt, based on the amount of gas emitting from them. I feel I need to go over how volcanoes are formed.

    ReplyDelete
  65. This past week we learned about volcanoes. We learned the gas levels can help us predict when a volcanoe will next erupt based on the threshold. We learned that volcanoes form at plate boundarie and there are three types of volcanoes.Cinder, Sheield and, composite. Threshold Value is how much of something it takes to make something else happen. How much radiation it takes to make you sick, how much sun it takes to make you sunburned. Almost everything has a threshlod value. Also we immitated a volcanoe in lab but ours did not work. I never knew so much!

    ReplyDelete
  66. This week in science class we mainly learned about volcanic eruptions and factors. We also learned why they happen and what the different types of volcanos are. Magma is what fuels the volcanos when the volcanic gases push it closer to the surface. As the amount of volcanic gases increases, the amount of time until the volcano erupts decreases. We also covered the different parts of volcanos like the vent, crater, and magma chamber. The three different types of volcanos are shield, cinder cone, and composite. Lab was a good demonstration/summary of these concepts but it was kind of hard to get to work. I understand all the concepts though.

    ReplyDelete
  67. This week we learned about volcanoes. Volcanoes usually occur on convergent boundaries. The energy used when an eruption occurs comes from radioactive decay within the core of the earth. The amount of gas coming out of the volcano will determine how explosive the eruption will be. This can help determine whether an evacuation is needed.

    ReplyDelete
  68. Voclcanoes are found on a convergent plante boundary and the more gas released the more explosive the eruption is going to be. Geologists predict eruptions and to detremine whether or not evacation would be neccessary. in lab we model the gas emissions generated from a volcano.our job was to produce the threshold amount of gas. A threshold is the maximum amount of a substance that can be tolerated by a human without casusing danger or damage.

  69. This week we learned about volcanoes. We did a lab simulating a volcano erupting with acetic acid (vinegar) and sodium bicarbonate (baking soda). You could measure the amount of gas produced by the amount of water displaced into the gradulated cylinder. We learned what fuels volcanoes, what the parts of volcanoes are, and what types of volcanoes there are.

  70. This week we learned about how volcanoes act, and the parts of them. In lab we tested how much gases could be released from baking soda, and acetic acid.

  71. This week we learned that a volcanoe's energy comes from Earth's core. As well we learned that they are usually found on convergent plate boundaries. In class we learned that new crust is created by divergent boundaries. In lab we learned how and why scientists collect gas emissions from volcanoes. Scientists record the value of threshold from the gasses given off by volcanoes to be able to determine when it would be needed to evacuate based on the gas level. As well we learned that volcanoes are easier to predict a period of time when a disaster might occur based on the gases released, while earthquakes do not give obvious signs.

    ReplyDelete
  72. This week in lab we learned about the “threshold value” which is critical to know in order to protect people from disaster. The threshold value is the breaking point, or the point at which lives are in danger. Having knowledge of the threshold value of volcanoes is critical in predicting if a violent volcanic eruption is brewing. We also learned that evacuating people before the threshold value of a violent volcanic eruption, is critical because if people are evacuated at the threshold value it could be too late, which is why it is, “better to safe than sorry”.

  73. This week i thought the lab was really fun, i think it did a good job of showing how volcanic eruptions happen. even though i got 0ml or water for all but one trial i thought it was fun how we got to see what actually happens inside a volcanoe. one thing im still confused on is were do all of the gases come from and how do they form? also congrats mr. Boyce on canada beating u.s.a i told you we beat them by luck!

  74. This week in lab we learned the substances that are released from the emmision of a volcano. We also reviewed the layers of the earth and the plate boundaries that are formed and what is firmed by each boundary.

    ReplyDelete
  75. This week we went into detail about volcanoes. We learned how gases can set off the eruptions from the volcanoes and different parts of volcanoes. Volcanoes are made of vents, craters, and magma chambers, and can emit ash clouds that can be tephras or volcanic bombs. Some different types of volcanoes are shield, cinder cone, and composite bombs. 95 % of volcanoes occur on convergent and divergent boundaries.

    ReplyDelete
  76. In lab we did an example showing how people can predict when volcanoes will erupt. They know one will erupt because of the gasses it releases just before shooting out magma. Volcanoes are very different form earthquakes because you can predict them and you cant predict earthquakes.

  77. This week we learned about the threshold value of something or the maximum amount of a substance something can withstand. We learned about isotopes and how to find the number of protons and neutrons in that isotope.

  78. This week we expanded our learning of plates by studying volcanos. We learned what how they are formed andwhat the effects they have on humans. We also learned about threshold and how it applys to volcanos.

  79. This week we learn about volcano's and why it is important to check there gas levels and there threshold so we can predict when it will erupt.

    ReplyDelete
  80. This week in science I leaned about volcanoes! I learned how they are formed. Also I learned why they erupt, so much gass build up causing pressure and will pass the threshhold making it explode. It is crutial we check the amount of gass to hopfully know about when they will erupt.

    ReplyDelete
  81. This week I learned that a fresh hold is the amount of something a human can take to a curtain extant like you cant have too mutch medicine soda or anything really you can get sick. I also learned that scientist can get an idea when a volcano will erupt by looking at rocks that shoot out of the volcano in aan euruption and that we can get an idea when a volcano will erupt but we have no idea when an earthquake will erupt.

  82. This week in lab we learned about volcanoes, threshold values, isotopes, and touched the topic of radiation. In lab we experimented with the threshold values of volcanoes and how they are important in determining the safety of volcanoes. If the gasses that are in a volcano rise and are near the threshold value, the volcano will likely erupt and therefore it is unsafe. It is impossible to pinpoint the exact time a volcano will erupt but volcanologists can get fairly close using the gasses they collect, whereas earthquakes are completely unpredictable. Threshold values are simply the amount of something it takes for something else to occur. We also learned about isotopes which are atoms of the same element that has a different number of neutrons, We also talked about the different types of radiation that are created by the core of the earth.

  83. This week we learned about Volcanoes and how they are formed.I leraned that there is more than one type of volcanoe there are three types of volcanoes. The first one is the Shield Volcanoe the Shield Volcanoe is formed by layers of lava accumulate from non explosive eruptions,it's the least explosive and it's the wildest in sze. The next Volcanoe is the Cinder Cone Volcanoe it is formed when tephra falls back to earth and piles around the vent,it is intermidiate when it comes to exploding and it's the smallest one. The last volcanoe is the Composite Volcanoe it's formed when layers of volcanic fragments alternate with lava, very explosive most dangerous volcanoe and it's the tallest volcanoe. That's what i learned this week.

  84. This week in lab we learned about volcanoes. We learned about the threshold value which is how much something can handle before something else happens. We learned that it is easier to predict when volcanoes are going to erupt and that it is easier to study them than earthquakes. WE learned the different types of volcanoes and which one is the most dangerous.

  85. this week we learned more about volcanoes, and which kind of plate boundary they lie on. We also did a lab on how to collect samples of volcanic gasses, and how they use those to determine the size of explosion and when it will explode., we also touched on the topic of radiation at the end of the week.

  86. This week in science we learned all abou volcanoes and did some review plate boundrys. We learned about how much gas is being realesed will help predict when and how explosive a volcanic eruption will be. Radiation was also disscussed for a little.

  87. We learned about volcanoes and how scientists test for them. They test the gasses to determine how big the explosion will be. In lab, we tested for gasses. We had an error in our data so we didn't get to 150ml of water, so we had to guess. We also talked a lot about the threshold amount of an object. This is the amount of something that an object can hold without sideffects.

  88. We learned about what makes up volcanoes. In lab we larned about transferring gas with water to create another liquid and carbon dioxide. Also we learned about the threshold value for things. The threshold value is the limit of what somethin gcan hold. If a place will evacuate people, they should do it before the threshold value is reached because it will soon cause harm to humans. I finally got a refresher about density calculations and convection currents.

  89. This week we learned about volcanoes and threshold values. In lab we had an experiment on threshold value using vinegar and baking soda. The reaction gas pushed it into another beaker. Then finally it pushed water through a pipe like thing into a graduated cylinder. This easily helped explain and show the transferring of gases.

  90. This week in class we discussed volcanoes and the gases involved with them. We also talked about where and how they can form. in lab we learned about how the gases can propel something out of the vent.

  91. this week in class we talked about the different gases and whats in the gasses the makes volcanoes so bad. And where in the earth its located and how toxic or stuff like that

  92. This week we learned about how volcanoes can be predicted and which boundaries they usually occur on, and earthquakes cannot be predicted. We also talked about how plate tectonics cause earthquakes and volcanoes.

  94. This week we learned about volcanoes and threshold value and I learned that if a volcano reaches threshold value then scientist need to evacuate town.In lab we tried to find out what the threshold value was and when to evacuate.

  95. In lab we learned about how gases leached from volcanoes can be measured. And how they can be used to determin how volatile an eruption would be and if it is in danger of erupting. The rest of the week seemed like a review.

  96. In lab we learned about how high ammounts of gas levels can result in the evacuation of cities around volcanoes becasue when high amounts of gas are in a volcano it is going to erupt sooner than a volcano with less gas, we studied this in lab by using 2 beakers and puting baking soda and vinigar in one and then mesuruing how much gas pushed water from another beaker out into a measuring cylinder. this showed us that the threshold value of volcanoes can determine how violent the eruption will be and when it might be. thus, an evacuation of surrounding cities with an active volcano with a low threshold value.

  97. This week in science we learned a lot about volcanoes. We learned that volcanoes have three major parts, the vents, the crater, and the magma chamber. We also learned that the Magma chamber is a full of magma , whcih is a mixture of molten rock. I thought it was cool that falling ash could turn day into night, even though it isn't that cool for the people in the area when that happens.

  98. This week we learned about volcanoes.
    We learned that volcanoes can be at convergent, divergent boundaries and Hot Spots.There are 3 types of volcanoes; shield, cinder cone and compostie. We also learned what the threshold value was. I am not unsure of anything we covered this week.

  101. I feel like I understand all of the terms we have covered this week. I could not get our experiment to work during lab. It was frustrating, but I still do think I understand all of the vocab words and such.

  102. This we learned in depthly about volcanoes. Specifically, there are 3 diffirent types of volcanoes; sheild, cinder cone, and composite. In lab, we learned about the diffirent types of gasses volcanoes can emit, and how to trace them.
