Week of 9/28/2009

The ideas I learned this week in Science class is that water reflects objects because light bounces off the water and in all different directions, including into our eyes. We also learned that every object has a high or low focus. A mirror has a very high focus and a solid brick wall has a very low focus and cannot reflect many things-light just doesn't reflect off of it well.If light bounces off the water and in all directions than we should be able to see ourselves, but we couldn't. So we disproved our hypothesis' one by one to get the best answer.

I learned these ideas by experimenting and making H-D statements. I made hypothesis' and predictions and then tried proving them wrong or right. I would come up with 3-5 hypothesis' and then come up with an experiment to prove each one wrong. The one that i cannot prove wrong is the one closest to the truth.

It is important to know these ideas because then the next time you look into a pond you know why you see yourself. It is important to know how light bounces off things because when you get old enough to drive you know which way to turn your side-view mirrors. This knowledge can come in handy in many different ways.
