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
3. Test tube stand
4. Bread
5. Banana
6. Styrophone
7. Brown paper/cardboard
8. Water

Steps:

1. Collect your materials from your science teacher.
2. Put the banana, styrophone, paper/cardboard, and bread into their own test tubes.
3. Add half a tube of water to the bread.
4. Write the names of your team members down so you know whos thing is whos
5. Set them out and wait for your results.
