Done by Group:ABH-Qatar-7 School:Ahmed Bin Hanbal school for boys Module Polymers: Through this module, students examine the different properties of the variety of polymers. Then they design and test a humidity sensor made of a polymer film. Finally, they are asked to design their own products. This project explores the basic physics of bridges. The goal is that the student will develop an understanding through experimentation of which shapes are the most structurally strong, and that many factors are taken into account in engineering and building. The project provides a practical application of physics to a real-world context. We add rubber to sand,cement ,gravels and water .

3. Introduction
Definition of polymers
Macromolecules consisting of a large number of correlation of small molecules
with each other, and these are called small molecules (monomers).
Types
1. Polymers as well:
Polyethylene: plastic.
Poly Vinyl Chloride (PVC): tubes, bags, vials.
Poly-Acrylonitrile: synthetic fibers such as Alawrlon.
Poly Styrene: plastic jewelry.
Poly butadiene: synthetic rubber.
2. Condensation polymers:
Polyethylene terephthalate: Synthetic fibers of poly ester type.
Glues: packaging, plasticisers.
Nylon 66: Synthetic fibers of nylon g
Phenol formaldehyde: adhesives such as Bakaleight.
Polyurethane: foam rubber used in insulation and upholstery

15. The more molecular weight of material
increases strength and decreases stretch
ability and The less molecular weight of
material decreases strength and increases
stretch ability

17. Our project idea is mixing a polymer of high strength
(rubber) With concrete to avoid the speed destroying of
constructions so we can use it in many fields for
Example:
Buildings and bridges
