Polymers, Al-Tafkeer Group ,Clay and heating ,IDM8

Done By :Al-Tafkeer Group 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. Clay and heating :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

  • 19. 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
