Polymers, Al-Tatweer Group ,New Dye ,IDM8

Done By :Al-Tatweer School Name :Al-Shamal Independent Secondary school for Girls 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. New Dye :The idea is about use the glass in dye to make it better . We get our idea from the soil on the street .

  • 3. ? :Polymer • Are a large class of materials consisting of many small molecules (called monomers) that can be linked together to form long chains, thus they are known as macromolecules. The picture at the top of the page is a short section of such a chain. A typical polymer may include tens of thousands of monomers. Because of their large size, polymers are classified as macromolecules.
  • 4. Activity 1 .Changing polymer pellets Tools Prepare -1 two 0.5 g of the polymer .pellets Add 10ml of plain -2 water to each beaker , allow the mixtures to .sit for 10 min remove the samples -3 from the beakers . Then measure and record the mass of each .sample add 10 ml of -4 water to sample A and add 10 ml salt water to sample B and sit of for 10 min filter any -5 leftover liquid from the beakers and measure it .again
  • 5. Activity 1 .Changing polymer pellets SAMPLE A SAMPLE B Before the experiment After addition the water Increase 10 ml of water g 0.5 g 10 g 19 :Conclusion Before the experiment After addition the water Increase 10 ml of salt water 5g .0 g 10 g 9 When we adding water to the polymer, the polymer Increased size and dilation, but when we put salt water the polymer diminish Weight and this is Back to Property spread .

  • 7. Activity 3 Comparing the viscosity of : Viscosity .liquid viscosity, resistance of a fluid to flow. This resistance acts against the motion of any solid object through the fluid and also against motion of the fluid itself past stationary obstacles. Viscosity also acts internally on the fluid between slower and faster moving adjacent layers.
