2. Outline
• Introduction
• Activity 1: testing different type 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 : Changing heat energy to electric
energy

3. composites
• Materials made up of two or more
visibly distinct substances are the
materials features in this module.

4. Activity 1: testing different type of ice
• We tested 3 different type of ice :
• First: plan ice
• Second: ice + tissue
• Third: ice + anything(straw + paper + cotton + sooth pack)
• Then we put them in the freezer and make them ice

5. Activity 2: hunting for composite
materials
• We searched about composite materials and
there are our result
Composite material
name
We use it for
Glass fiber swimming pools and
car manufacturing
Carbon fiber Wind power
generators

6. Activity 3: exploring the difference between
strength and stiffness
• We take different materials and compare it
and those are the result
Object name Strength flexibility
Wood 4 4
Plastic rod 3 2
Nylon 2 1
pasta 5 5
Iron rood 1 3

7. Activity 4: testing a foam composite
for strength and stiffness
A. Plain foam beam.
B. One side paper: a foam beam with think paper glued to the bottom.
C. Two sides paper: a foam beam with thick paper glued to both top and
bottom.
D. Disjoint: a foam beam with paper glued to the toped bottom; paper
glued to bottom has a disjoint-a gap in the middle of the beam where
the paper is not glued down well.

9. design project: designing a fishing
pole
• we design a fishing pole and we used many
different type of materials
The Fishing pole should be:
- Flexible
- Strong
- Lightweight

10. Final Project:
(Title: changing heat energy to electric energy)
• Introduction and Rationale:
• Our project is changing heat power to electric
power.
• For example when we drink a coffee we can use the
heat of the cup to charge our mobile.
• It will be a nice idea if we work on it.
• Aim of the work (objectives):
• to save energy.
• To charge the mobile in an emergency situation.
• You can use any type of heat to make it useful.

11. Hypothesis:
•
Hypothesis of the study :
1 How can we benefit the society to save energy?
2 How can we change the heat energy to electric energy?
