Week 5 This week we worked on changes of state and things on dry ice and nitrogen. I will talk about dry ice and nitrogen. First off, with dry ice, it's change of state is called sublimation or else it goes straight from a solid to a gas. It changes state from a solid to gas at -109 degrees F. If you touch it while it is a solid you will get freezerburn which is where it aborbs all liquid in you cells and kills your cells. One of the demonstrations we saw on nitrogen was where you putt regular water and a little dish soap in and then you mix it up and put the dry ice in and when the bubbles come up if you pop them there is CO2 inside of the bubbles.

Week 4 There was lots of stuff i learned this week. one thing i learned is about Ecological Succession. Things like primary succession and Secondary succession. Primary succession is where a community starts to grow where other organism had not previously lived.

Week 3 1. This week i learned alot. One thing was how the food chain works. First you have your sun. Then you have your producer which uses the suns energy to make it own food called photosythasis. Then the primary consumer eats the producer. Then the secondary consume eats the primary consumer which then when the secondary comsumer dies, decomposers such as bacteria and mushrooms and such clean it up or decompose it.



rnWeek One 4-9-09

1. This week one thing i learned is about the cell theory. The first part of cell theory is that all cells come from existing cells. The second part is al lorganisms are made of one or mor cells. and the third on is the basic unit of all living things. There were three scientist who contributed to it. On wis a scientist Matthias Schleidn who studied plants. Theodor Schwann who studied animals. And finally Rudolf Virchow who was a doctor.

2. Another thing i learned is the main functions of the lysosome, and the golgi complex and a ribosome. First off with the lysosome, what it does is fights off foreign invaders and gets rid of waste. Next is a golgi apparatis which packages proteins and sends them out of the cell. i even made a comic strip about it. Finally the ribosomes whih makes the proteins for the golgi complex to package.

3. One question i had is while we were working on toondoo.com and i was wondering how if the right props weren't there that you needed what should you do. I didnt know if you could make the prop you needed like you do when you make your own character. i could have used that tool. although i didn't look very hard..but oh well right

Practice week 3-17-091. Today i learned that there is lots that you can do to customize your page on this wiki space. one thing you can do is add your own pictures which is pretty fun because it is what you like. Also, i learned that you can update anybody's page and mess with them except it will say that you did it in the history and who did it and what they did. I want to know what else we can do to customize our wiki's and how much we are aloud to update them and if we can make them very flashy and also can we change the background color of just our wiki page.
