Hurumanu - Decomposing and Recycling

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

Hypothesis: I think that...... The Banana would rot first

Materials:

1.   Banana
2.   Bread
3.   Test tubes
4.   Cardboard
5.  Styrofoam 
6.   
7.     

Steps:

1.   Get your test tubes and put them in the holder
2.   Get your ingredients ( Banana, Cardboard, Styrofoam, Bread )
3. Put your banana in the tube
4.  Put the cardboard into the tube 
5.   Put the Styrofoam into the tube
6.  Put the bread in the tube  

Findings:

•   The Banana did rot first over the course of the 2 weeks
•   The cardboard and the Styrofoam did absolutely nothing
•   The bread was the second most disgusting
• 
  

3 weeks	Colour	Change	Observations
Banana	Green, brown , black and a little bit yellow	It has got alot of mold on it and it looks very fuzzy	Its brown and furry all over with green and black bits
Cardboard	Its still brown with no other colors	Its almost the exact same as last time nothing has changed	Its still the same no massive changes
Styrofoam cup	White still	Nothing has changed at all	Its still the same
Bread	Its green and brown with a gross looking orange water substance	Its gross and furry green and has deflated quite a lot

Conclusion: In conclusion the Banana did rot first  and the Styrofoam had no effect what so ever, the cardboard was almost the exact same as well, I think the bread went just as bad as the banana but like I said the banana roted first.
