2. Outline
• Introduction
• Activities (Summarize all activities in 2 slides)
• Product Idea

3. Introduction
Polymers are giant chain molecules made of
small repeating unit called monomers

4. Activity (1,2)
Activity 1: Changing
Polymer Pellets
Activity 2: Hunting for
Polymer Products
Soil moist (Polyacrylamide) is
a synthetic polymer when
placed in water can absorb
over 200 times of their
weight.
We used internet to search
about natural and synthetic
polymer and their properties
also the meaning of the
recycling codes

5. Activity (3,4)
Activity 3: Comparing the
Viscosity of Liquids
Activity 4: Testing the Strength
of Different Polymer Films
In this activity we explore
the effect of polymer
molecular weight and
concentration on the
viscosity of polymer
solutions.
In this activity we Test and
Compare the stretch ability
and tensile strength of
polymer films having
different molecular weights.

6. Design Project
Design project: Designing a humidity sensor
In this activity we design a humidity sensor
made from a polymer film, which change colors
according to the humidity level.

7. Healing Band Aid

8. Healing Band Aid
Introduction
• The purpose of the bandage is to protect a small to medium
sized wound or scab. This includes keeping the site clear of
friction, bacteria, damage, or dirt, enabling the healing
process to proceed undisturbed.

9. Healing Band Aid
Aim of the project
• In this project we aim to design a band aid
made from natural polymers such as honey,
and cyperus

10. Healing Band-Aid
Hypothesis: (‫)الفرضية‬
Using honey and cyperus in the Band-Aid will aid
in speeding up the healing process

11. Healing Band-Aid
Methods and Materials
We are going to mix honey and Cyperus to make
a paste which will be added to the Band-Aid

12. Healing Band-Aid
Results: (‫)النتائج‬
• The healing properties in the natural polymers are
good addition to the Band-Aid to speed up the
healing process.

13. Healing Band-Aid
Recommendations: (‫)التوصيات‬
• More researches to be done to develop this
product to implement this idea in the existing
Band-Aid to help in the healing process

14. Conclusions
(Overall of the whole module)
Throughout our experience in al-Bairaq we have
gained different important skills and knowledge,
such as presentation skills, research skills, and
problem solving.
