Done by group: Alieman_Creators School Name: Al Ieman school for girls Biodegradable Materials module: Students make, test and evaluate biodegradable films and gels. They use their knowledge gained during the workshop to design devices that release a dye in a controlled manner as they degrade. Finally they design their own biodegradable product Students decided to make a natural biodegradable pot. The main purpose of the project was to reduce the amount of waste and pollution caused by non-biodegradable plastic by making a safer, and more eco-friendly replacement which is the biodegradable plastic pot.

Hair

7. Procedure: Testing two different packing peanuts in water.
Result: while testing the white and green peanut inside water
we got the results shown in the table:
White peanut Green peanut
Starch Polystyrene
Natural polymer Synthetic polymer
Biodegradable Non-Biodegradable

9. have the same physical property which is
protecting fragile items.

11. Biodegradable
materials
Non-biodegradable
materials
Are objects that
degrade by nature .
Materials that takes
long time to
decompose or may
never decompose in a
landfill no matter how
long it is there.
Ex: banana peels Ex: plastics, leather
baseball gloves
