Hurumanu / Science Decomposing and Recycling

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

Hypothesis: I think Banana or Bread will rot the faster because banana will get warm and it will get all rotted and Bread can get all soggy.

Materials:

1.  Bread + water.
2.  Paper.
3.  Banana.
4.  Styrophone.   
5.  4 testTubes.  
6. Test tube rack

Steps:

1.   Collect the Materials abd take them to your table.
2.  Sort out the Materials.
3.  Add all the 4 equipment into the 4 tubes.
4.  Get a sticky note off the teacher and write your groups name.
