Decomposition/Recycling - Hurumanu

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

Hypothesis: I think that either the banana or the bread with water is going to rot the fastest.

Materials:

1. Bread  
2. Water  
3. Paper 
4. Banana  
5. Stylophone  
6. 4 test tubes  
7. Test tube rack  

Steps:

1. Collect materials  
2. Sort out the materials in the correct order 
3. Add in each of the 4 equipment in each separate 4 tubes 
4.  Get a sticky note from the teacher and write your names on it

Findings:

3 weeks	Colour	Change	Observations
Banana	Green	Rot	It turned into green rot
Paper	Brown	Nothing changed	Nothing changed, it still looks the same
Stylophone cup	White	Nothing changed	Nothing changed, it still looks the same
Bread	Light Brown	Mushy	It turned into this weird

Conclusion:

In conclusion, I would like to say that I have learnt a lot.  I have out how long it takes for stylophone to rot it takes thousands of years.  So that means that it takes the longest to break down.  Banana is also the easiest to rot out of the four it had already gone mouldy.  I'd like to finish off with I would like to do this again and bye.
