Hurumanu - Decomposing and Recycling

• Aim: To learn about the rate that different materials decompose.
  Hypothesis: I think that the bread will decompose the fastest because it is placed in water.
  
  
  Materials:
  
  
  1. Test tubes x 4
  2. Corks x 4

  4. Bread
  5. Banana

  7. Brown paper/cardboard
  8. Water
