1) The document outlines activities conducted by a student group to learn about composite materials. They tested different types of ice and natural/industrial composites to explore their properties. 2) The group then examined the difference between strength and stiffness by testing various materials. They also analyzed a foam composite to determine if it was stronger than plain foam. 3) As a final project, the group designed a garbage container for electronic waste made of different composite layers to safely store and allow for recycling of e-waste. The container was meant to reduce environmental hazards from chemicals in disposed electronics.

2. Outline
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 :Designing a fishing pole
• Product Idea: Garbage container for electronic
waste

3. Introduction
• A composite material : is a material made
from two or more constituent materials with
significantly different physical or chemical
properties that, when combined, produce a
material with characteristics different from
the individual components

4. Activity 1: Testing different kinds of ice
We took 3 sample
Sample (1): water
Sample (2): water + tissue
Sample (3): water + tissue + cotton
Result:
Sample (3) is the strongest one and sample (1) is
the weakest one.

5. Activity 2: Hunting for composite
materials
Natural Composites:
wood
Industrial composites
Concrete

6. Activity 3: Exploring the Difference
between strength and stiffness
We tested different materials for
strength and flexibility
Strong → weak
1-iron
2-nylon cord
3-plastic
4-wood
5-pasta
Most flexibility → least flexibility
1-nylon cord
2-iron
3-plastic
4-wood
5-Pasta

7. Activity 4:Testing a foam composite
for strength and stiffness
Result:
Sample (3) is the strongest one and sample (1) is the
weakest one.
Foam composite is stronger than plain foam

8. Activity (5) : Designing a fishing pole
1}strong
2}flexible
3}light
We designed a fishing pole
from different materials
The fishing pole must be:

9. Final Project:
Garbage container for electronic waste
• Introduction and Rationale:
Electronic waste cause serious health and pollution problems if
not disposed in a safe way. Rapid Changes in Technology have
resulted in a fast-growing surplus of electronic waste around the
globe. The chemicals in the mobile phones can leach from
landfills into the groundwater system and cause hazards . Our
product will help to protect the environment from the hazards of
the electronic waste by specifying a Garbage Container for the
electronic waste to be easily separated from the non electronic
waste and recycled.

10. Garbage container for electronic waste
Hypothesis:
• Specifying a certain container for the
electronic waste will help us to separate it
from the non electronic waste and to be easily
recycled.

11. Garbage container for electronic waste
Methods and Materials
This electronic waste container will be
joined to the main garbage container
and made from:
1- the inner layer : foam
2- the middle Layer : Heat insulator
3- the outer layer : Iron

12. Garbage container for electronic waste
Results:
• Our product will help to separate the electronic waste easily
from the non electronic waste
• The separated electronic waste can be used for recycling
• Our product will help to reduce the hazards of the electronic
waste on the environment

13. Garbage container for electronic waste
Recommendations:
• We recommend our product to be used
everywhere .
• We recommend that every building has a
garbage container for the electronic waste

14. Conclusions
We had knowledge from Albairaq workshops
about the composites and the importance of
Composites in our lives. We trained on how to
do a presentation and how to think of creative
ideas.
