Done by Group : Inventors School Name : Alshahaniya Independent Secondry School for Boys. Polymers 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 product Idea is : using Polyacrylic Acid incubating factor 8 to stop bleeding for Hemophilia peoples.

• Introduction
• Activity 1: Changing polymer pellets
• Activity 2: Hunting for polymer products
• Activity 3: Comparing the viscosity of liquids
• Activity 4: Testing the strength of different
polymer films
• Design Project (Designing a Humidity Sensor)
• Product Idea (Carbopol stops bleeding of

3. Introduction
 Polymer is Large molecules
composed of a correlation large
number of small molecules with
each other, and these small
molecules are called (monomers).

4. Activity 1
Changing Polymer Pellets
 Objective : Understand how Polymer pellets work.
 Procedure :
1) Prepare two samples 0.5 g of polymer pellets
2) Add 10 ml of water to each sample , then observe the
results
3) Measure the mass to each sample
4) Add 10 ml of plain water to sample A , & 10 ml of
saturated salt water to sample B , then observe the results
5) Filter leftover liquid to make samples easier to handle, by
using paper towel , then measure the mass of samples

5. Activity 1
Changing Polymer Pellets
 Results : Polymer absorbs water , so the mass of pellets
increased in both samples after addition of plain water
for the first time.
Sample A absorbed more water after addition of plain
water for the second time
Sample B released the water after addition of the salt
water
 Conclusion : water moves through polymer depends on
Osmosis of water ( moving of water molecules from low
salt concentration to high
salt concentration ) .

6. Activity 2
Hunting for polymer products
• Objective : Make a data table that contain :
1) Name of products made of polymers
2) Uses of products
3) Type of polymer ( natural / synthetic )
4) Name of polymer
5) Physical properties of the polymer
• Procedure :
1) List in data table the polymer products in the room , then
describe its uses
2) Determine type of polymer ( natural / synthetic ) , then
identify the polymers name
3) Describe the physical properties of the polymer
4) Compare the number of polymer products , then identify
products as being made of polymers

7. Activity 2
Hunting for polymer products
• Results :
• Conclusion : Polymers ( natural or
synthetic ) are used & found in most of
products in our life

8. Activity 3
Comparing the Viscosity of Liquids
 Objective : Knowing about the viscosity of liquids & the
amount of time that bubble takes to move through
each liquid
 Procedure :
1) Examine the liquid of each vial , then record the
observation
2) Turn over the vials , then record the time that it takes
air bubble to reach to the opposite end by using
stopwatch

9. Activity 3
Comparing the Viscosity of Liquids
 Results : Bubble moves faster in Methanol
, then Ethylene glycol , then Glycerol
have the slowest movement
 Conclusion : Polymers with higher
molecular weight have highest Viscosity ,
& Polymers with lower molecular weight
have less Viscosity

10. Activity 4
Testing the strength of different
polymer films
 Objective :
 knowing the strength of different polymers films
 Procedure :
 label two microslides with the molecular weight of one
of the poly(vinyl acetete) Solutions .
 Use the pipette to draw the appropriate poly(vinyl
acetate) solution.
 Dispense the solution from the pipette as evenly as
possible onto the unlabeled side of one of the slides .
 Use a coin to drop a watch glass over the two slides .

11. Activity 4
Testing the strength of different
polymer films
 Results :
PVAc 260 have the highest strength.
PVAc 100 have the lowest strength.
 Conclusion : when the molecular
weight increase the strength of the
polymer films will increase.

12. Design Project
Designing a Humidity Sensor
 Objective: Design a Humidity Sensor
 Procedure :
1) Design a thin polymer film made of three
different polymers
2) The sensor must be durable
3) The sensor contain Cobalt (II) Cholride as
indicator ( blue – dry , pink – wet )
4) The sensor gives visual response within 10 min
5) The sensor have reversible response

13. Design Project
Designing a Humidity Sensor
 Results : Sensor number 3 that
made of polyvinyl alcohol gives the
best model of humidity sensor
 Conclusion : the best polymer that
used in humidity sensor that have
less molecular weight

14. Product Idea
Carbopol stops bleeding of Hemophilia peoples
 Introduction and Rationale:
 The idea of the project is finding an effective and
practical treatment for people with hemophilia
 Aim of the work (objectives)
 This project aims to find an effective way to stop
bleeding when people with hemophilia been
injured

15. Carbopol stops bleeding of
Hemophilia peoples
 Hypothesis :
Polyacrylic Acid that incubate factor 8
can stop bleeding for Hemophilia
peoples.

16. Carbopol stops bleeding of
Hemophilia peoples
 Product Story :
Through working with Al-Bairaq team we
learn a lot about polymers, specially that
some polymers have ability to incubate
materials, & be gel-like shape.
So we think about using gel as a medicine
to stop bleeding of peoples, specially
Hemophilia peoples that faces difficulties
to stop bleeding.

17. Carbopol stops bleeding of
Hemophilia peoples
 Materials :
1) Polyacrylic Acid (Carbopol)
2) Factor 8 of Hemophilia
3) Buffer solution
 Methods :
Adding Factor 8 of Hemophilia to
Polyacrylic Acid, then mix them with
buffer to get a gel in natural pH .

18. Carbopol stops bleeding of
Hemophilia peoples
 Results : Inventors Gel stops local
bleeding from the skin of Hemophilia
peoples.
This is the first medicine that use factor 8
incubated in a gel, so its efficient for
Hemophilia peoples.

19. Carbopol stops bleeding of
Hemophilia peoples
 Recommendations :
We recommend pharmaceutical
factories to use & develop our medicine.
Cost-benefit of the project are high,
because its unique medicine of external
use to Hemophilia peoples.

20. Carbopol stops bleeding of
Hemophilia peoples
 Conclusion :
Using of Inventors Gel Stops local
bleeding for Hemophilia peoples.
We get high experience by participate
with Al-Bairaq competitions.
