Hurumanu - Decomposing and Recycling Science

Hurumanu - Decomposing, and Recycling Science

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

Hypothesis: I think the banana is going to rot the fastest

Materials:

1. Bread + water.
2. Paper.
3. Banana.
4. Stylophone.
5. 4 test tubes.
6. 1 test tube rack.
7. Scissors.

Steps:

1.  Get your 4 tubes and place into the test tube rack
2. Cut the stylophone out, the cardboard/paper
3. Place the banana and the bread in the test tubes
4. carefully add water into the test tube with bread.
5. Then add the stylophone and the cardboard into the test tubes.
6. Then wait for 3 weeks to see which one rot first 

TODAY	Colour	Change	Observations
Banana	yellow	No
Paper	brown	No
Styrophone cup	white	No
Bread	white	No

3 weeks	Colour	Change	Observations
Banana	Yellow	Brown/Green	The banana was yellow the changed to Brown with green rot
Paper	Brown	Brown	The paper stayed Brown
Stylophone cup	White	White	The Strophone Stayed white
Bread	White	Yellow	The bread was white the changed to yellow

5 week	Colour	Change	Observations
Banana	Yellow	Rotten green	The banana was rotten
Paper	Brown	Brown	The paper stayed Brown
Stylophone cup	White	White	The Strophone Stayed white
Bread	White	Yellow	The bread was  yellow

Conclusion:
This experiment was really fun but also disgusting.
The banana 3 weeks later was brown and also green it was very smelly and was rotten.
Paper 3 weeks later stayed the same.
The stylophone sup stayed the same it was still white.
The bread 3 weeks later Turned yellow and also a little bit smelly.


5 weeks later the banana was just all rotten and green.
5 weeks the paper stayed the same.
5 weeks later the stylophone stayed the same.
5 weeks the bread was yellow and also a little bit green.
