water cycle

This week in science we learned how the water cycle works. We mainly focused on the evaporation part of the cycle. We learned about how the water evaporates into the air and how the molecules evaporate. When the sun heats the water it transfers energy to the particles The energy the sun is transfering is kinetic energy. The kinetic energy makes the particles speed up and spread out. This is how a themometer works. Except the solid particles vibrate causing the particles in the mecury to react. I am starting to understand the water cycle more.

more evolution

This week in science we learned more about evolution. We learned about the iguanas in the Galapagos. We learned how they got there through gene flow. Such things as water wind and birds brought things to the islands. Also, I think that if the water ever dropped far enough down to creat a land bridge, many orgamisms could have travled across. Friday we had a test that covered everything we learned. I think everyone should have done decent if they were able to grasp the idea of evolution. I am pretty sure I did.

Scienceeeee

This week in science we learned about natural selection or selective breeding. This tied in with the category of adaption. Adaption is when organisms change over time to best suit their enviorment.The processes that change them are natural selection, mutations, and selective breeding. When change occurs too fast, the organisms will die out because they don't have enough time to adapt. This will cause a drastic change in the population.

cockroach test

This week in science we did an experiment with cockroaches. We were allowed to design our own experiment which was a little challenging. My group wanted to see what surfaces the cockroaches liked. When we were planning the test, we did not consider every variable. This is what I learned about designing experiments. You must consider all variables. In our test the cockroach would go where it could get shade which we forgot about. We also did not have the same amount of space for each surface. Next time I design an experiment I will make sure I consider every variable before I start gathering materials.

Camp Spears

1. I learned that in a bog, things will stay preserved because the sunlight cant get to the water so there is no oxygen in it.

2. I learned that there is a magnetic pull on the north pole which makes a compass face north.

3. I learned that salamanders live in streams near lakes.

4. I learned that birch keeps mosquitoes away when burt because of a chemical in the wood.

5.I learned liken is etable.

This week in science we made observations on cockroaches. An observation is something that you notice using all of your senses except for taste. (when working in a lab) Many people were very uneasy around the cockroaches and they could tell. Our class made great observations. We all noticed that there were small tanish colored bugs crawling on the cockroaches. I think that they could be baby cockroaches. I think this because they are generally the same shape of the grown cockroaches. Also, many of the roaches have missing antenii. This could be due to fighting over a mate which is common. We also made detailed drawings of them. A few seemed to be dying so they were easy to draw. They could be diseased or very old.

Reebop Project

Genetic variety was how the genes spread without direct breading. This is how people ended up with so many bugs in their family even though they only bread with 3 people. If I bread with someone and then they bread with someone, they will probably have some of my traits. I ended up with genes from 5 different people besides me. This is how the parent bugs phenotypes are so different from the F3 bugs phenotypes. I could end up looking like bugs from all over the place. This is also true about the real world. Genetic variety is how genes spread so fast and so far.
