decomposing and recycling

DECOMPOSING AND RECYCLING

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

Hypothesis: I think that......this is a good thing that this experiment is what we are learning today.

Materials:

1.   paper
2.   banana
3.   bread
4.   Styrofoam 
5.   4 Test Tube
6.   water
7.     Test Tube rack

Steps:

1.   first you need to go to a group
2.   then you need to get the 4 Test Tube and the tube rack 
3. after you got the test tube you need you have to get the Styrofoam, banana, bread and the paper that you going to put there 
4.   and after you got all the things that you need you should put the Styrofoam, banana, paper and the bread in different test tube
5.   then you need the paper to right your groups names on it.
