Decomposition

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

Hypothesis:
I think that the Banana and Bread will get rotten first before the other ones because they are food and the other materials are a bit more solid. The Bread will have Water with it so it will turn soggy and not as solid as before.

Materials:

1.   1 x small slice of Bread + Water
2.   1 x strip of Paper
3.   2 slices of Banana
4.   1 strip of Styrofoam 
5.   4 x Test Tubes
6.   1 x Test Tube Rack

Steps:

1.  Get your Test Tube Rack then put the Test Tubes inside.
2.  Put two slices of Bananas inside one of the Test Tube.
3.  Put the slice of Bread inside the other Test Tube and so on. 
4.  Put Water with the Bread.

Findings:

TODAY	Colour	Change	Observations
Banana	Brown	None	Still the original.
Paper	Brown	None	Still the original.
Styrophone cup	White	None	Still the original.

Conclusion:
This Experiment was really fun and exciting. The second recording that I got was really surprising. The Hypothesis that I did was right but the bread didn't actually had water in it but still got Mushy. We are still doing the experiment and waiting for another 1 to 2 weeks and see what it looks like after 5 weeks.
