Decomposing

Aim: To learn about the rate that different materials decompose. 

Hypothesis: I think the bananas will decompose faster because if you unpeeled the banana and you leave it, it will get rotten fast. 

Materials:

1.   bread
2.   test tube
3.   white styrofoam
4.   paper
5.   banana
6.   stand for the test tube
7.  rubber stopper
8.  water

Steps:

1.   get 4 test tubes and 1 test tube stand
2.   cut the banana, bread, styrofoam, and cardboard so this fit at the test tube  
3.  put the banana and etc. at each test tube
4.   put the rubber stopper at the top of the test tube.
5.   wait until change.
