Done By Group : KHA_Beta8 School Name : Khalifa Independent Secondary School for Boys. Biodegradable Materials: is a substance that degrades into smaller nontoxic parts that are returned to the environment and may be reused by organisms. there are so many applications around us for Biodegradable materials like : Surgical Sutures , Plastic bag . our Idea:Bio Plastic Palm tree is a part of our culture and it is widespread Qatar, it has many uses but we think about it as a Biodegradable Material. We use “palm tree” to make Biodegradable plastic form natural components: Starch + Water + Vinegar + Glycerin

7. Product Idea: Bio plastic

3. Introduction
• Biodegradable Materials: is a substance that
degrades into smaller nontoxic parts that are
returned to the environment and may be
reused by organisms

4. Activity1:Comparing Packing Materials
Objective:
To pack some eggs in two packing materials (a
biodegradable & a non- biodegradable) to see
which is the better in protecting the eggs.

5. Activity2:Comparing Packing Materials
Conclusion:
The two packing materials gave the same
protection to the eggs but the biodegradable
one dissolves in water.

6. Activity3:Hunting For Biodegradable
Materials
Objective:
To know what biodegradable material do
everyone have in there houses.

7. Activity3:For Biodegradable Materials
Observation:
We found that most of things in people houses
are made of non-biodegradable, and a lot of
other things are made of biodegradable.

8. Activity3:Processing Biodegradable
Materials And Comparing Their
Mechanical Properties
Objective:
To processing and comparing the mechanical
properties of
biodegradable materials
Procedure:
By putting different amounts of gelatin, and HCl
we made three different types of gelatin films
(5% w/v, 10% w/v, and 20% w/v gelatin films).

9. Activity4:Measuring The Degradation
Rates Of Biodegradable Materials
Objective:
measuring the degradation
rate of Biodegradable
materials
Procedure:
By using NaOH, HCl, boiling water, and normal
water to degrade the 3 films we made before,
and gelatin capsules, and some foam to
measure the Degradation rates of them.

10. Activity4:Measuring The Degradation
Rates Of Biodegradable Materials
Conclusion:
Boiling H2O HCl NaOH
Foam 17 min 55 min 33 min
5% Gelatin Films 3 sec 18 min 36 min
20% Gelatin Films 9 min 30 min 63 min
Gelatin Capsule 4 min 45 min 1 hour, 5 min

11. Design Project: Designing A Medicine-
Delivery Device
Objective:
To design a device that will effectively deliver
medicines inside human body.

12. Bio Plastic
Introduction and Rationale:
Palm tree is a part of our culture and it is widespread Qatar, it has many uses
but we think about it as a Biodegradable Material.
We use “palm tree” to make Biodegradable plastic form natural components:
Starch + Water + Vinegar + Glycerin
• Aim of the work (objectives) (‫البحث‬ ‫)هدف‬
Our product can help the environment by replacing plastic waste which cause
harm to the atmosphere, plants, and animals.

13. Bio Plastic
Results
• Our product may be used in many ways such as
making Biodegradable plastic bags, dishes,
disposable utensils and silverware.
• Our product will solve many problems like water
pollution.

14. Bio Plastic
Recommendations
• We advice everyone to try using our product
for lots of new applications.
• Our product need to be improve by
researchers and if we have to try many times
to get the right ratio for all components.

15. Conclusions
(Overall)
In AL-Bairaq we have gained a lot of skills and
benefits such as:
1. scientific research
2. Preparing to university
3. Development of practical laboratory skills
4. Team work
5. Communication skills
6. And lots of other benefits.

16. Acknowledgment
Thank you all people who helped us going through Al-Bairaq
especially Mrs. Marwa and Mrs. Ruba the research assistances
from Qatar university.
And the biggest thank must go to Mr. Mohamad who
encouraged us all the time.
And we thank Al-Bairaq team and the sponsors who gave us the
opportunity to participate in Al-Bairaq project, create and
innovate.
