  1. This week in science we learned about the carbon cycle, and how carbon travels from one place to another. In lab we learned about a chemical that was in our water that was affecting the fish. We learned that eventually what was happening to the fish would happen to us as the amount of the chemical increased as you went up the food chain. For example, when one small fish eats something with the chemical and another bigger fish eats it, that chemical is absorbed by the bigger fish. As the bigger fish continues to eat smaller fish with the chemical the more of that chemical it will have. When we finally eat that fish the chemical could be rather high, and as we continue to eat fish with that chemical it could start to effect us.

  2. This week in class we learned about chemicals and how they can effect the environment and the things in the environment. We learned about a chemical that can change the appearnce and almost the sex of a small minnow. We learned that it mimects estrogen and is given off by a power plant.

  3. This week we learned more about the food chain and how if a chemical gets into one organism low on the food chain, it can impact other organisms that comsume the chemicals. In lab, we learned that if a female hormone is added to a male species, that male might loose some secondary sex characteristics. In the case of the minnows, the characteristics included the tubercles and the height of the pad fat. We also learned about the carbon cycle. Because we are carbon based organisms, our world revolves around the amount of carbon and the consistancy of carbon in our atmosphere.

  4. This week in science we learned alot about the carbon cycle. I was confused at first about how it worked going from one cycle to the next. I am still a little confused but understand it more now. We also learned about the food chain and how chemicals can effect an animal who eats another animal and passes it on. In lab we used minnows to test how a chemical can effect a male minnow. Overtime the chemical did effect the minnow. This is related to the carbon cycle because mostly everything needs or has carbon.

  5. This week I learned that male minnos that live in a contaminated lake over time start to react to the chemical. In the water there was a form of estrogen, the male fish started to get smaller i size and have less nuptial tubercle. They were starting to get woman qualitys.

  8. This week in science we learned about the effects on minnows when they are infected with estrogen and we also learned more about the carbon cycle. In lab we counted the dots on the face of the minnow which was the nuptial tubricals and we measured the dorsal fin fat which helped understand the sperm count. With the carbon cycle we learned what the carbon goes through to get from on stage of the Earth to another.

  9. This week in science class we learned about how we, humans, have an affect on the biosphere. We learned how when we dump estrogen, a female sex hormone, that the male minnows are affected. The research shows that they have been losing secondary sex charictaristics. This is a big deal because if we are also dumping these chemicals into our drinking water then we could possibly take on the same affects as the minnow. Overall this week we have learned that we have a direct impact in our biosphere and how it operates.

  10. This week in science we learned about the effect humans have on the biosphere. We learned that when water is polluted with estrogen that their secondary sex characteristics are effected. We larned that these effects may be similar in humans and other animals. We learned about the carbon cycle and how carbon moves thorough the boisphere.

  11. This week in science class we learned about the carbon cycle. We learned that carbon can move through the earth in many different ways. One of these ways in photosynethsis, when plants exchange carbon dioxide for oxygen. Another one of these ways is when humans burn fossil fuels. This releases extra carbon dioxide into the atmosphere. In lab, we learned about female hormones polluting the water. These hormones give fish secondary sex characteristics that cause them to lose some of their male characteristics. The result of this was that the fish lost body weight and lost some of their nuptial tubercles, which look like spots on their face.

  13. This week in science class we learned about carbon dioxide emissions which effect the atmosphere here on earth. The main source of carbon dioxide in the atmosphere is from burning fossil fuels. Fossil fuels release large amounts of carbon dioxide into the atmosphere. This carbon dioxide traps heat, and the more we have the hotter the planet will get. If we do not reduce the amount of carbon dioxide in the atmosphere soon our planet could experience dangerously high temperatures which could effect the earth in many ways.

  14. This week in class, we learned about the effects of chemicals and what happens when human activity interferes with the environment. The most interesting thing I learned was that when chemicals are added to lakes and other ecosystems. It affects the genetic make up and sexual charateristics of the fish and animals near the affected area.

  15. This week we learned alot about the human impacts on the bio-sphere. We did worksheets that showed how much extra carbon we add to the atmosphere, and how it is causing our planet to heat up. In lab this week we did an expiremenet that showed how the chemical estregen effected a mals fish's dorsal fat pad height and secondary sex charateristics required for mating. We also learned alot about how carbon is tranferred through the bio-sphere and from place to place.

  16. This week in lab we learned about the effect estrogen has on male minnows when it is exposed. The tubercles and the height of the pad fat of the fish changed as the more days he was exposed to it went on. In lecture class we have been learning about the carbon cycle. We went station to station and had to find the right piece of paper that said the right way we got there.

  17. This week in science we have been learned about the carbon cycle. We did a game that you had to figure out how sea plants went to volcanoes and how volcanoes went to plants. It was all very interesting but took a lot of thinking to come to conclusions sometimes. I also learned that everything on Earth is all carbon based. We need carbon but you need to equal it out and burning fossil fuels is one thing that throws off the system. Everything using it, like plants, has to be equal to where it came from.

  18. This week in class we learned about the carbon cyle. In lab we learned about how certain chemicals can affect the traits of an animal species. On Wednesday we did the carbon cycle activity and learned the process in which carbon is transfer from one place to another. I think it helped to write down all the processes and connect them because they are easier to remember.

  25. This week on class we talked about the human's role in the biosphere. We also studied the effects we have in the carbon cycle, and what happens when we interfere too much. In lab, we studied the effects of some waste that contains the female hormone estrogen, and it's effects on the male minnow. I learned that when the fish are introduced to too much if the hormone, they lose their secondary sex organ things. Which can mean that they won't reproduce anymore, causing a major decrease in the tiny fish population, and it can throw off the food Chaim. So pretty much if people continue everything, the food Cain might be completely destroyed.

  34. This week in class we learned about the carbon cyle and each process that takes place in the transfers form one place to another. Some tracnsfers were photosynthesis, combustiona dn respiration. It is pretty remarkable to learn how everything is connected. Also in lab we learned about the effects that estrogen has the secondary sex traits in male minnows.

  38. this week in science i learned about the carbon cycle and how it as recycled in the bio-sphere. the game thing we did in class helped me understand how it works. i also learned about minnows in lab and how if they are exposed to a female hormone they start losing their manly traits and start getting more feminine.

    ReplyDelete
  39. This week we finished up on talking about how carbon dioxide gets into plants, the ocean, and the atmosphere. In lab we learned about how dumping things near water supplies like rivers can affect us and the creatures that live around it. We use the bolder creek as our example and the minnows that live in it. We had to see the changes that male minnows had when exposed to a female growth hormone. We had to see if the fish got skinnier and we saw how many dots we on its face.

  40. This week in science i learned a lot about the carbon cycle. Taking the journey as carbon was an interesting way to learn about the carbon cycle. It was also important to learn the different reasons carbon travels through the cycle. Also, the volcano in Iceland that erupted was a real world application of some of the stuff we learned this year.

  41. This week in lab we performed how male's secondary sex somethings would be changed if they had female hormones, haha! and to demonstrate that! we got to dignose fishies, during this we discovered that at the top there would be none to it just because its obvious that the hormones have not swam up stream, but the 50% was greater, and 100% was the greatest. This relates because the fish outer characteristics changed which can conclude that, that might happen to humans if we performed the same lab.

  50. This week in science class, we continued to learn about the carbon cycle. We learned a lot about how carbon moves and travels from place to place. Some of the ways that carbon moves are by photosynthesis and the burning of fossil fuels. We did an activity where we went around to different stations of places that carbon could travel to and then we had to explain how the carbon would move from other places to that spot. In lab, we learned about and did an experiment about how male minnows are affected by estrogen, a chemical in the water that is a female hormone.

  65. In class this week we learned about the carbon cycle. We learned that carbon can go anywhere in the world in any form. In lab we looked at male minnows and how they are effected by estrogen. We measured the dorsal fat pad and as the minnow was in the estrogen for a longer time, its dorsal fat pad decreased.

    ReplyDelete
  66. This week we went into detail on carbon and how it travels through the carbon cycle. Carbon comes from the death of animals and plants, animal waste, and the burning of woods and fossil fuels. Combustion, respiration, and deforestation release it into the air, and photosynthesis pulls it back down. Decomposition and sedimentation harden it and turn it into the fossil fuels we use. Diffusion, circulation, and rock formation and weathering cycle it around the earth.

  70. This week we learned about the effect of pollution on wildlife. When production waste chemicals are released into the atmosphere, all forms of life are effected someway. To help preserve wildlife, we must tighten control on what is released into the open. We also learned about the carbon cycle. The carbon cycle recycles all the earth's carbon over and over again in many different ways.
