Education

AL-Bairaq

Done by group: Alieman_Inventors
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.

As in Qatar we depend on sea water, student thought of an idea that protects the marine environment in their country. After performing research, it was found that some fishermen forget where they put the Gargoors or fishnet in seawater, causing the fish to be captured and trapped for a long time. The Gargoors get heavier and settle in the bottom where there is no enough oxygen, sunlight, or food. The fish will die but nets still there that causes the cycle continues. This cause huge pollution. Accordingly, the product of this group represents a solution to this problem. This could be achieved by using biodegradable materials to make a lock for the Gargoors that degrades within few days in water to give freedom for fish without affect the environment.

INTRODUCTIONBiodegradable materials are objects or substances that may be decomposed by the environment or by organisms.

ACTIVITY 1 COMPARING PACKING

MATERIALS

Part A: Result: white peanut dissolved first.

•Objective : Comparing different packing materials

Part B:

Result: both eggs were broken at nearly the same height.

ACTIVITY2HUNTING FOR BIODEGRADABLE

MATERIALS. Biodegradable materials: are substances or

objects that degrade into smaller nontoxic parts that are returned to environment or organisms.

Examples;

Banana peel Papers

wood Non-biodegradable substance that cannot

break down. Examples;

plastics metal glass

PROCESSING BIODEGRADABLE MATERIALS AND COMPARING THEIR

MECHANICAL PROPERTIES.

ACTIVITY3

Preparing gelatin films We prepared gelatin

films with different concentrations. We found that the strength of the film increases as the concentration increases.

Testing mechanical properties

We tested the mechanical properties of the gelatin films

DESIGN PROJECT: DESIGNING A MEDICINE-RELEASE CAPSULE

ObjectiveSimulation of drug release & capsule degradation that happen in human body

We added sodium alginate to calcium chloride to get Alginate beads “natural polymer”

Page 10: Biodegradable Materials, Biodegradable Gargoors and Fishnets, IDM7

Design Project: Designing a medicine-release capsule

1-We made the alginate beads which represents the drugs’ capsules

2- adding food coloring, which represents the drug, it will be absorbed by the capsules .

3- Extra dye will be removed from the beads

4- Finally we dropped the beads inside sodium citrate solution which represent the human blood to see the dye diffusion.

WE LEARNED THAT DRUG CAPSULES CAN SAFELY DEGRADE IN HUMAN BODY AFTER MEDICINE DIFFUSION

Problem and project idea: While most groups were focused on land pollution, we were more concerned about our aquatic environment which surroundsmost of our beloved country.

Firstly, we asked ourselves “what is the problem with our aquatic environment which could be solved using biodegradable material?”. After a lot of thorough researching and asking professionals specialized people in the ministry of environment, we recognized one of the biggest causes of sea water pollution.

• Aim: To protect the marine environmentand save the fish.

Some fishermen forget where they put the gargoors or fishnet, causing the fish to be captured and Trapped for a long time. The fish will die, nets still there that cause the cycle continues. This will affect the fish wealth. All this dead fish will cause several other severe problems, such as increase the bacteria which causes a decrease in the level of oxygen in water. This will lead to the death of other marine creatures. being a huge cause of pollution.

WE TRIED TO CREATE A SOLUTION. IF WE USE A BIODEGRADABLE MATERIAL WHICH CAN DEGRADE QUICKLY THE FISH WILL SURVIVE AND OUR ENVIRONMENT WILL BE SAFE
