Done by Group: IT-Future-7 School: IBN Taymiyyah school for boys . Polymer Module:Through this module, students examine the different properties of the variety of polymers. Then they design and test a humidity sensor made of a polymer film. Finally, they are asked to design their own products. The aim of this product is to reduce the danger of explosion of gas cylinders. This explosion that causes death and destruction by using Silicon(Interpon HT ) . Our main is to save lives and keep people safe.

.Design Projects:
1)Designing a Humidity Sensor
.Project Idea:Heat resistant gas cylinder

3. Introduction:
Polymer are long chain molecules made of small
repeating molecules called monomers

4. Objective :
The students learn about the polymer and its properties and
how they can contribute in this activity .
Activitie 1
Changing Polymer Pellet

5. Procedure:
Activitie 1Changing polymer pellet
We add 0.5 g Sample of
the polymer to beaker A
and B
We add (10) ml water to
beaker(A) And add (10)
ml salt water to beaker (B)
Remove the samples
from the beakers
Compare what Happening
to the pellets in salt water
and fresh water at the
same time.
Now, We filter the liquid
from the beakers
The polymer that was in
fresh water swell put with
salt and water shrink

6. Results:

Mass after
20 min 15.6 g
Conclusion: when we add fresh water to the
polymer, it swells because absorb the water to the
polymer. When we add salt water, the polymer shrinks
because the concentration of water fresh inside the
polymer greater than the outside salt water .

9. Comparing the viscosity of liquids
Activitie 3
Part A
Objective:
To know about the Viscosity of several liquids and its effects
Procedure:
We add the liquid in
Each Vial
We turn up down each
Vial .
Observe the air bubble
in each vial.
Conclusion :
viscosity
increases
Introduction: Viscosity is The resistance Of a
Liquid To Flow .
MW
increases

10. Activitie 3
partB
Objective:
Change the shape of the polymer
Procedure:
Comparing the viscosity of liquids
We Make a mark on
each of six pipettes
7.0 cm
Fill a pipette to 7.0
cm
Now we work in
poly(vinyl acetate)
we spreading the
polymer in slide
We wait 24
hours
Spreading polymer solutions

11. Results:
Conclusion: (part B )we can change the shape of the polymer

12. Activitie 4
Testing the Strength of Different polymer Film
Objective:We Can Make polymer Film and Test the Strength of polymer film
Procedure :
We Have to peel
polymer after 24 hours.
Test hardness of film
poly(vinyl acetate)
M.W .100.000
Repeat Test hardness
poly(vinyl alcohol)
M.W.170.000

14. Designing a Humidity Sensor Design Projects
Introduction: Design a Humidity Sensor Made Of a Polymer film That
Changes Color as the Moisture level in its Environment Changes.

15. Designing a Humidity Sensor Design Projects
Procedure:
We Add polymer Film Made Of
Poly(Vinyl acetate) M.W.2,000
(4) Times Measured 4.5cm
And we Add Indicator(cocl2)
(2) Times Measured 4.5cm
And We Add Water (4)
Times Measured 4.5cm
When We Mix, It Turns the
Color to the Pink
We Dry the slid until it
changes to Blue. And we have
to Note The Time Change To
Blue
We Put the slid on Steam
Until it Changes to Pink by
Humidity

16. Designing a Humidity Sensor Design Projects
Results:
When Exposed to Humidity
needed only 11 . Seconds
turn to pink
We Need To Dry The Sensor
for 6 Minutes turn to
blue
Conclusion.When Humidity Sensor is Dry ,The Color changes to Blue .
When Exposed To Humidity, it Changes To Pink color.

17. My project
Heat resistant gas cylinder

18. Introduction and project
1: The reasons why we are interested in this project is to reduce the danger of
gas, this project is about developing gas cylinder resist heat and benefits the
Qatari community from explosions.
2: We have been attracted by the explosions that happen in the world because
of the gas cylinder and especially the explosion that happened in Qatar near
landmark and the newest thing about our project is to produce a gas cylinder
that resists heat that reduces explosions that cause death.
3: We had little information about polymer before Al- Bairaq come to our
school but Al-Bairaq helped us with the activities that taught us a lot about
the properties and characteristics of polymer and also some of its usages
here we had the idea of using polymer in producing things and objects .
Reasons to
Heat resistant gas cylinder

19. Objectives the project
The aim of our producer is to reduce the danger of
explosion of gas cylinders ,this explosions can cause
death and destruction our main is to save lives and keep
people in safe.

20. Hypothesis of the theory
Name of the component : Interpon HT (Silicon)
Of the most important features that it bears very high temperatures and very low it
bears more heat.
Of 300 ° C and a low temperature until - 100 ° C and it has a high degree of resistance
Ozone and weather conditions in general, as well as an insulator of electricity. Anti
flam property has any flame resistance.

21. 1:The aim of the component: to be used as a heat –insulating
2:How to use it : the polymer will be used as a material for
coating gas cylinders and to act as heat –insulating which will
make cylinders more secure and protected from high
temperatures
Hypothesis of the theory
Procedures:
(1) Find heat resisting polymer
(2) Find the polymer additives to acquire the high capacity of thermal insulation
(3) We reached the conclusion that Interpon Ht polymer is the best insulator of
heat

22. Results
To perform our project we used an organic silicon polymer heat.
using this kind of polymer will solve the problem of high
temperature in gas cylinders.
Heat resistant gas cylinder

23. Recommendations
We recommend innovators and scientists to search for heat –
resistant polymer
And used in new products and development in order to maintain
the safety of people.

24. Conclusions
We have benefited from AL- Bairaq and its presented projects
which enabled us to
Know more about polymer and now we have a better idea
creating projects Through activities.
