Anyways today in class we started our ELODEA experiment. Are materials that we used in the experiment was 20 m. of water and codiun bicarbonate some part of the class has less amount of tablets then other people,so that we can see who's plant can see how many bubbles come out of the plant. the order that we did the experiment is that we did:



First: weigh the tablet



Second: we crush up the tablet until it turns into dust( make sure to crush the tablet on paper or something that wont change the weight)



Third: after u crushed up the tablet weight it again so that u have the same amount as you had before.



Fourth: we ruins out our test tube then dry it, after that Finley gave use a special water to put the tablet and plant in.



Five: then we but the tablet in the test tube before the water.



sixth: poor in the special water CAREFULLY if you have a big amount of tablets it might be fizzy



eight: put the plant in the test tub....wait a min. then start counting the bubbles for 5 min.

Spontanious Generation

Today in class we talked about people in the 15oos-1800s and how they thought people got sick. We all said that back then they thought that bacteria, viruses, parasites,germs etc. just came out of no where, just magically appear and began to get you sick. For example if they left out meat for 4 days outside it will attracted flies which will lay eggs and then the eggs that the flies put in the meat become maggots. Then the maggots will have put bacteria, and germs on the meat. But back then they thought maggots spontaneously appeared out of the meat. But what really happens is that the flies laid the eggs on the meat,which then turn in to maggots. That's how it really happens, but back then they didn't know what to think.

We also talked a little bit about how fungus and chemicals can also get you vary sick. And that back then they didn't know about it so they didn't really wash there food vary well, and then that's when the fungi's starts to grow all over the food. As you eat the food with fungus on it you become to get sick and that's not good at all.

Another thing we did in class today was a little activate but sadly we didn't really start it, but most of my class mates began to read the article to begin the activate. The article was mostly about bacteria what i was talking about before about the maggots, flies, and meat and how it really happens.
