This document outlines activities and experiments conducted with polymers. It includes 5 activities: 1) changing polymer pellets by adding water, 2) identifying natural and synthetic polymer products, 3) comparing viscosity of liquids, 4) testing strength of polymer films, and 5) measuring water absorption of polymer films. It also describes a design project to test strength of polymer films and prototypes. Key findings include that polymers absorb or release water differently depending on their characteristics, and viscosity increases with molecular weight. The document concludes with acknowledging sponsors of the research.

2. Outline
• 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
polymers films.
• Activity 5: Measuring water absorption by
different polymers films.
• Design Project : Testing the strength of different

3. Polymer is a molecular compound
distinguished by a high molar mass,
ranging into thousands & millions of
grams, & made up of repeating units
(monomer)

4. Activity 1: Changing polymer pellets
1 - Writing the Data
2- Sort tools
3- Prepare two 0.5 g of
polymer.
4- add 10 ml of water . 6- weight the samples after
10 min .

5. Abstract:
Sample “A” absorb the water
swell
Sample “B” release the
water
“ shrink
Conclusion:
* The polymers have Characteristic absorption due to polar.
* The polymers have Characteristic edit the water because of
the characteristic propagation .

6. Activity 2: Hunting for polymer products

8. Activity 3: Comparing the viscosity of liquids
* The viscosity :
The viscosity of a fluid is a measure of its resistance
to gradual deformation by shear stress or tensile
stress.
* Conclusion:
The relationship is Proportional
between Molecular Weight and
Viscosity .

9. Activity 4: Testing the strength of different
polymers films
2-Sort tools.
1 -Writing the Data
3- Solution of poly(vinyl acetate

10. Activity 4:Testing the strength of
different polymers Films . (Part 2)
1-Sort tools.
2- Skimming slot
3-Individual slot 4-In the end

11. Conclusion
# Cobalt chloride turns to the color blue in
the middle Dry
# Cobalt chloride turns to the color pink in
the middle wet

12. Activity 4:Testing the strength of different
polymers Films .

13. Assigning Prototypes for Design
Project 1 :
1-Sort tools.
2-Make a mark on a clean pipette 7 cm
from its tip .
3- use the pipette to draw one of the
solutions up to the mark .
4- add 5 times polymer .
5-Add 3 times Indicator .
6-Add 2 times solvent ratio .
7-Mixing the solution
8-Exposed to moisture
9-Exposure to drought

15. The projects' problem
Hot drinks temperatures decreases quickly,
especially in winter. So the idea of our
project was painting hot drinks cups with clay
polymers to keep its temperature as long as
possible

16. The Idea of the project:
Using naturally made clay
polymer after making
It from: starch, soda, oil and
water.

18. Polymer clay safety is the
subject of concern
specifically the long-term
effects of exposure to
certain phthalate plasticizers

19. We found out that clay polymer
keeps the temperature of hot
drinks cup for the longest time

20. 1- using the accurate quantity of materials
in making clay polymer leads to good
results .we tried preparing cay polymer with
in accurate quantities ,but the experiment
failed
2- Naturally made clay polymer is very useful for
children. It can be used for making shapes and
toys for children
3- clay polymer must be perfectly ( solute
din order to use it properly and well
