This document outlines a student project on biodegradable materials. It describes 4 activities: 1) comparing biodegradable and non-biodegradable packing materials, 2) identifying biodegradable objects, 3) processing and testing biodegradable materials, 4) measuring degradation rates of materials. It also details a design project to create medicine release capsules and proposes a slimming belt made of natural materials like ginger to help burn fat. The document acknowledges support from teachers, AL-Bairaq team, and sponsors for the project.

5. Activitiy(2)
Should Be
Biodegradable
Reasons Should Not Be
Biodegradable
Reasons
Plastic Bags It being using a
lot ‘ to help
environment
Chairs Because it will not
degrade in wet
weather
Drinks bottles Because it used
daily by
enormous
amount
Cars Because it is
expensive and will
protect us from
the heat and rain.
Hunting For Biodegradable Objects

6. processing Biodegradable Materials and comparing
their mechanical properties
We use HCL and gelatin
capsules to make 2
films with different
concentration of
gelatin 5% and 10% ,
also we made a gel
with 20%
concentration .

7. measuring the degradation rates of Biodegradable
Materials
HCL 0.0001 m Na(OH) 0.0001 m Boiling water
Foam Peanut 2:15 8:23 0:32
Gelatin Capsule 8:40 9:20 0:55
5% Film 1:15 3:20 4:30
20% Gel 18:40 18:20 12:30
We measured the degradation rates of different
Biodegradable Materials in different solutions
CONCLUSION : ALL Biodegradable Materials
DEGRADE FAST IN BOILING WATER , AND IT
DERADE ACIDIC SOLUTIONS FASTER THAN
BASE SOLUTIONS .
ACTIVITY (4)

8. DESIGNING A MEDICINE
RELEASE CAPSULES
• WE DESIGINING CAPSULES FROM SODIUM ALGINATE AND
CALCIUM CHLORIDE.
• THEN WE PUT THEM IN SODIUM CITRATE TO DEGRADE AS
THEY CAPSULES DEGRADE IN OUR STOMACH .
DESIGN PROJECT

9. Slimming Belt
A lot of people suffer from obesity in
gulf , so we decided to make a
slimming belt made of natural
materials mainly ginger as it has the
ability to burn fat. The belt will
degrade after a period of time.
