2.   Beaker holder
3.   bread
4.   banana
5.   styrophone
6. cardboard  
7. water    
8. 
   

Steps:

1.   Get your materials

Findings:

TODAY	Colour	Change	Observations
Banana	Green	shrunk	it shrunk and has green mould growing
Paper	brown	nothing	it has stayed the same
Styrophone cup	white	Nothing	it has stayed the same
Bread	yellow	Melted	the bread soaked up the water and melted

• the banana started to shrink  
•   the paper stayed the same
•   the styrophone cup did not get effected
• the bread started melting

3 weeks	Colour	Change	Observations
Banana	green	shrunk	it shrunk and has green mould growing
Paper	brown	nothing	it has stayed the same
Styrophone cup	white	nothing	it has stayed the same
Bread	yellow	Melted	the bread soaked up the water and melted

•   the banana got more green and hard
•    the paper stayed the same
•   the styrophone cup did not get effected
• the bread melted more

5 weeks	Colour	Change	Observations
Banana	green	shrunk	it shrunk and has green mould growing
Paper	brown	nothing	it has stayed the same
Styrophone cup	White	nothing	it has stayed the same
Bread	yellow	melted	the bread soaked up the water and melted

  

•    the banana was like a curled stick with mould on it  
•    the paper stayed the same
•     the styrophone cup did not get effected
•    the bread melted into a hard liquid

Conclusion:I enjoyed this experiment and I learned that bread and water dont mix and banana goes hard and curly with mould on it.
