2. • Introduction
• Activity 1: Testing Different Kinds Of Ice.
• Activity 2: Hunting For Composite
Materials.
• Activity 3: Exploring The Difference
Between Strength And Stiffness.
• Activity 4: Testing A Foam Composite For
Strength And Stiffness.
• Design Project Design A Fishing Pole
• Product Idea

3. Composites are made of two or
more different materials .

4.  We have took three samples and filled them
with water , sample A was plain , ice sample
B was ice with tissue & sample C was ice
with cotton , wood & straw
 We have found that sample C was the
strongest
 The more materials we put the strongest the
sample becomes

6. We have found that
almost everything is
composite for
example : the plane
is made up of steel
and aluminum , the
steel to make the
plane tough and the
aluminum to make it
light weight

7. Activity3:Exploring The
Difference Between Strength &
Stiffness
We have took five materials 1st one
was iron rod 2nd one was wooden
stick 3rd was plastic rod 4th was
nylon cord & the last one was stick
of pasta and tried to bend them .
The result was
Object name strength Flexibility
wood 4 4
Plastic rod 3 2
Nylon cord 2 1
pasta 5 5
Iron rod 1 3

8. Activity 4 : Testing A Foam Composite
For Strength And Stiffness
To Test How The Composite Material Works We Have Brought
Three Foams The 1st One Was Normal Foam 2nd One Is With
Paper In The Bottom Of The Foam & The Last Foam Is Either
Sides With Paper Then We Have put A Weight To See How
Much They Would Bend Without Breaking

10. Designing A Fishing Pole
We Used A Straw A Tape A
Toothpick And A String To Make A
Fishing Pole

11.  Introduction and Rationale:
our project will be used to
decrease accidents and will save
life of people by adding shock
absorber to the cars.

12. Adding the shock absorber to the
cars will decrease Car accidents.

13. The shock absorber consists of
three layers made of rubber and
copper . The copper is added to
make the shock absorber
strongly attached to the car

14.  Our invention will prevent car accidents
and save life of people

15. We recommend our product to be
sold everywhere.
Our product need to be more
developed

16. Many thanks to AL-Bairaq team 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.
