Week 5 May 21, 2009

1. This week I learned tons of things! I especially enjoyed doing the experiments with the liquid nitrogen. Liquid nitrogen boils at -320 degrees farenheit. I thought that it was cool how when the lettuce became frozen from the nitrogen it just shattered when it dropped. Then, when the penny sat in the nitrogen for awhile it would break into pieces. Pretty much everything that went into the nitrogen would become very brittle, and it would break.

Week 4 April 30, 2009

1. This week in Science I learned about Biomes. There are four main biomes, Desert, Grassland, Forest, and Tundra. There are many other biomes but these are the main ones other ones are mountains, Savanna,and chaparall. I also learned about how there are two black holes in space and one of the black holes is circling around the other they are

Week 3 April 17, 2009 


 * 1) In Science this week memorized all of the levels of environmental organization. These levels are organism, population, community, ecosystem, biosphere. I learned that the biosphere is 12 miles thick. I also learned that there is 3 levels of consumers, primary, secondary, then top. I learned the full definition of scavengers. Scavengers eat the remains of dead animals. I also learned what carnivores, herbivores, and omnivores are. Carnivores are meat eaters, herbivores are plant eaters, and omnivores eat meat and plants.



Week Two April 9,2009

1. In Science class this week I learned what a lot of the organelles in a cell do. I learned that ribosomes are protein and RNA, ER is what makes proteins and lipids, The cell membrane is what protects the things inside a cell and what holds everything into the cell. The cytoplasm is what gives the cell structure and the Nucleus holds the DNA and the Nucleolus which is what makes the Ribosomes. I also learned what the levels of Organization are first there is the cell then there is the tissue next is the organ and lastly is the organ system.

2. In class this week I learned that being multicellular has its advantages. There are three main reasons why. First, a multicellular organism is bigger, this means that they have more of a variety to eat. Second, they live longer. And last, since each cell has a specialized function so the organism would be way more efficient. Another thing that I learned is that dinosaurs are related to birds. I never realized that birds came from some dinosaur bird.

3. Something scientific that I would really like to learn more about is nanoparticles. I read a book on them and it was really interesting. Since, I have gotten information from the internet but I never really fully understood. I realize that they are some really tiny particles almost an atom. Also,

Week One March 19

1. In Science this week I learned about Prokaryotic and Eukaryotic cells. I learned that Theodore Schwann did the first two parts of the cell theory and that Rudolf Virchow wrote the third part. I learned that Archaebacteria and Eubacteria are both Prokaryotes. Eubacteria are plant cells, and Archaebacteria are animals cells. In class I also learned that both of them have cytoplasm, nucleus, nucleolus, vacuole, mitochondria, chloroplast, Endoplasmic Reticulum, Golgi Complex, and a cytoskeleton.

2. In class this week I learned how to use wikispaces. I learned how to put a picture on a wiki page, and how to change the font color, font size, and the font. I learned how to put in a Horizontal rule, this divides one peice of information from the next. I learned how to change my password on wikispaces and how to edit a page, before that I had to learn how to get added to a wikipage. I learned how to create a hyperlink and how to change the layout of a typical page of typing. 3. Something that I really wanted to learn about was

Practice Week March 17, 2009 Today I learned to use wikispaces. First of all, I learned how to edit a wikispace. I also learned how to put pictures on a wikispace. I would still like to learn how to create a hyperlink.
