I am Discovering Materials

2. Outline
• Introduction
• Activity 1: comparing packing materials.
• Activity 2: hunting for biodegradable object.
• Activity 3: processing biodegradable materials and
comparing their mechanical properties.
• Activity 4: measuring the degradation rate.
• Design Project:1.designing a medical delivery
device. 2.desgining new biodegradable materials

3. Introduction
Biodegradable materials are the materials that
are broken down by natural means like bacteria
and fungi.

4. Activity(1)
Objective: comparing packing materials.
steps:
1- put water in beaker.
2- Put the two peanuts in the beaker
3- start stop watch.
Results: the white peanut will degrade and
the green will not degrade.
Conclusion: water breaks the ponds between
the white peanut because its made of corn starch

5.  Objective: comparing packing materials
procedure: 1- put the two eggs in different cases and put
green peanut in the first case and white peanut in the other.
2- left them from same level
 Results: both white and green where protective to the egg
 conclusion: we can use both types of packing materials only the
white can not use it with contents containing liquid
Activity(1)

6. Objective: hunting for biodegradable object
Should be
biodegradable why
1- capsules To degrade in the stomach and give medicine to the body
2- plastic bags To decrease the pollution
Should not be
biodegradable Why
1- iron Because we use it in buildings
2- Rubber Because we use it in car’s tiers

7. Objective : making two films and one gel.
Procedure : 1- adding 10M of Hcl to three beakers.
2- add to the first beaker 5 capsules ,10 capsules
To the second and 20 capsules to the third.
3-Stir in a water path at 60C.
4- After wile put them in petri dish.

8. Results :
5% film 10%

Thickness thin Little thick Thick
Flexibility week strong Strong and flexible
transparency transparent Semi transparent Opaque

9. Activity(4)
 Objective: measuring the degradation rate

conc: the boiling water was the most effective at degrading because of its
kinetic energy that breake the bonds.
Measuring the degradation rate

10. Objective : designing a medicine release device.
Procedure : 1- add drops of food color to 5ml of sodium alginate.
2- we use the pipette to pulle the colored medicine and place it in a
beaker contains 50ml of CaCl2.
3- we took out the medicine and applied it on the filter paper.
Results: we made medicine by using food color and Na alginate and
CaCl2.
Conc: We could observe the release of color representing medicine.

11. Final Project
(Ancient bio gum)
Why ancient bio gum ?
The normal regular gum has many problems, it contains artificial colors,
Flavors, preservatives, sugar, plastics and rubbers. The sugar free gum
contains artificial sugar like aspartame which is carcinogenic.
Everyone prefer the gum because of its taste but this taste soon would
disappear leaving the sugar in mouth and giving chance of bacteria growth
causing (bad breath) and (tooth decay).
What if we can product a chewable gum for natural components and herbs
that can be used for many purposes?

12. Ancient bio gum
Tools:
Honey wax, gum base, Natural food color and Food essence.
Flavor: (Mint, Cinnamon, Clove, Rose, Ginger).
Method:
1. By mixing ingredients in blender for 30 min.
2. Pour the poste over modules and leave it.

13. Ancient bio gum
Results: we produce healthy bio gum with out artificial colors,
Flavors, sugar, plastics and rubbers.
We can use it in medical way as we can solve bad breath problem,
tooth problems, over weight……
It is not dangerous for children .
All of that by adding the natural medicine to the bio gum.

from Center for Advanced Materials (CAM), Qatar University for
supporting us during our journey with a AL-Bairaq.
Also, I would like to thank the sponsors UNESCO, Qatar National
Commission, Ras Gas, Maersk and Shell.
