Hurumanu - Decomposing and Recycling

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

Hypothesis: I think that the bread will rot faster.

Materials:

1.   paper
2.   banana
3.   bread
4.   stylophone
5.   x4 test tube
6.   x1 test tube holder
7.     tube blocker

Steps:

1.  Get the tube rack. 
2.   Put four test tubes in the rack.
3.  Get the four things that you need.
4.   Put the bread, banana, paper and stylophone in each tube.
5.   Put the test tube blocker on top.
6.   Record your info.
7.  

Findings:

TODAY	Colour	Change	Observations
Banana	yellow	nothing	taking half of the tube
Paper	brown	nothing	all of the tube and standing upright
Styrofoam cup	white	nothing	taking half of the tube
Bread	brown	nothing	taking 1/4 of the tube

•   The banana is yellow the takes half of the tube. no change
•   The paper is brown and takes all of the tube.no change
•   The stylophone is white and takes half of the tube.no change
• The bread is brown and takes 1/4 of the tube. no change

3 weeks	Colour	Change	Observations
Banana	white and green	rotting from the top	it's rotting from the top and the water is all in the bottom.
Paper	brown	no change	there is no change.
Styrofoam cup	white	no change	there is no change.
Bread	brown and white	rotting little	its rotting little bit.

After three weeks the banana is white the green it is rotting at the top and all the water is at the bottom.

After three weeks the paper was the same colour and did not rot down.

After three weeks the styrofoam was the same colour and did not rot down.

After three weeks the bread was brown and white and was rotating a little bit.

5 weeks	Colour	Change	Observations
Banana	green, black, white	The whole thing is rotting and liquidy at the bottom.	The whole thing is rotting and the liquid is all in the bottom.
Paper	brown	no change	there is no change.
Stylophone cup	white	no change	there is no change.
Bread	brown and white	rotting little and it is  like liquid	rotting little and it is  like liquid on top of the bread

  

•    The banana is green black and white The whole thing is rotting and the liquid is all in the bottom.

• The bread is the same colour brown and white  and it is rotting little and it is like liquid on top of the bread
•    The paper is brown and there is no change.
•   The is Stylophone cup is white and there is no change.

Conclusion:

The banana changed the most. It was rotting fast and it stinks It is also like a liquid at the bottom. The thing that was the same as the strat was the paper and the styrofoam. Both of them there the same that did not change at all. The bread changed but not lots. It was soft and was like cream on the top It did not change in colour but was rotting a little.
