This document summarizes activities and a design project exploring polymers. It discusses: - Activity exploring how polymer pellets change and hunting for polymer products. - Activities comparing viscosity of liquids and testing strength of polymer films. - A design project to create a humidity sensor using a polymer film that changes color with humidity. - A project to generate electricity by inserting piezoelectric polymer films under keyboard keys. The project aims to reduce energy consumption and hypotheses that pressing the keys will generate voltage.

2. Outline
• Introduction
• Activities (1,2,3,4)
• Design Project: Designing a humidity sensor
• P.G.K.B

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)
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 weight.
Activity 3: Comparing
the Viscosity of Liquids
Activity 4 : Testing the Strength
of different polymer films

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

7. P.G.K.B
Power generation by pressing the
keyboard

8. • Clean and efficient way of generating
electricity has been major topic ever since
humans realized how the conventional
sources of energy has been degrading our
environment.
P.G.K.B
Introduction

9. • To insert PVDF films under the keyboard
keys to generate electricity.
P.G.K.B
Aim of the project

10. • By using PVDF films in the keyboard will
generate electricity that can help reducing the
electricity consumption.
P.G.K.B
Hypothesis

11. P.G.K.B
Methods and Materials
• We will insert PVDF film under each key in the
keyboard, whenever the user press the key it
will generate electricity

12. P.G.K.B
Results: (‫)النتائج‬
• Inserting PVDF film in the keyboard keys will
generate voltage that could be used to reduce
the energy consumption in the laptop.

13. P.G.K.B
Recommendations: (‫)التوصيات‬
• Further researches could be done in this idea
to improve it
• The PVDF films could be used in the mouse
click button to increase the energy production

14. Conclusions
(Overall of the whole module)
• Polymers have different properties and uses
and could be applied in our daily lives to help
solve many existing problems.
