Polymers,

Done by Group: Bayan_Poly4 School: Al Bayan Sec. School Module Polymers: 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.

  • 7. Activity3(Comparing the viscosity of liquids) Viscosity is the resistance of a liquid to flow.
  • 8. Activity3(Comparing the viscosity of liquids) We saw the difference in viscosity in the liquids & observed that when molecular weight increase the viscosity increases.

  • 9. Activity4 (Testing the strength of different polymer films). :Part A Casting the polymer films.
  • 10. Activity4 (Testing the strength of different polymer films). :Part B We tested the stretch ability of the polymer films. 2. Folded them.1. Pulled out the polymer. 3. Measured the strength of each.
  • 11. The Result We noticed the difference in the strength of polymers. Time: Length: 0 2 4 6 8 10 12 14 16 18 20 0 60 120 180 240 300 360 410 470 530 PVAC1g/40 ml PVAC5g/40 m PVAC10g/4 0ml
  • 12. Design project (Designing a humidity sensor) First, we poured the mixture of indicator, polymer, and solvent on a piece of glass. After that, we placed the polymer sheet above water vapor & took observations.
  • 13. Product idea (Baby born bracelet) Our product is made specially for kids to help parents to detect the body temperature before getting sick. Because the high temperature destroyed brain cells . For that, we choose a sensitive polymer that changes in color along temperature & we found: MercuryPolydiacetylenes LiquidLiquidMatter SlowFastTemperature effect HighLowPrice
  • 14. The Result We found that “Polydiacetylenes” is the best polymer for our idea because it’s sensitive, cheap & easy to use.

  • 16. Conclusion We think that the temperature bracelet would be useful for a lot of people specially poor people because it’s cheep & easy to make.
