This week in science we put a green plastic ruler in a clear glass of water and wrote what we saw. What i wrote down was that when the ruler is ini the clear glass cup that is filled with water, the ruler gets larger in size. also when you put the ruler in the cup the water gets higher in the cup because it takes up a lot of room. Also since the glass cup is wide it makes the ruler look wide and longer then it really is. One of the diagrams is the light goes in all diffrent directions. This is because the glass didn't light up. Also when you put a ruler in a bucket which is clear the part that is in the water, its being destprted because the light but when the water hits the ruler the image is changed. That means its larger and wider.

This week we also learned about particles and waves. one thing they have inn common is that they both reflect things.

Well when you take a cup of water and point a laser at it some of the light will bounce off and some will just go through. We also learned about how light doesn't have any mass so it can't go all the way to the bottom of a cup. We learned about the wave model of light and the particle model of light.
