                                       My First Week at WAAS

My first week at WAAS began on Tuesday, October 15, 2013. On Tuesday we reviewed for the test on Wednesday. We answered and asked questions relating to the test. I learned about osmosis and diffusion. I also learned about DNA and RNA. Before, I did not know about osmosis and diffusion.I learned that osmosis is the diffusion of water molecules and diffusion is the movement of small molecules from a higher concentration to a lower concentration. On Wednesday we had the test. I learned how a test looks and how it should be taken. I need to improve on my studying so I can do better next time. On Thursday we went to clean up the beach. I learned that we should not use so much plastic because it could harm  animals . Plastic can harm sea life because they might think small bits of plastic might be food. When they ingest the plastic it harms them and eventually they will die. After cleaning up the beach, we made art out of trash. I think making art out of trash shows us another way we can recycle.

On Friday we did a paper chromatography with leaves experiment. I found  a similar  science experiment to the one we did in class. The link is below.We did not finish the experiment in class, but I predict that by the process of diffusion the plant pigment molecules will move from a higher concentration to a lower concentration on the paper as the pigment separates.
