Polymer with Banana toothpaste -IDM

Done by Group: ABH-Diamond-7. School:Ahmed bin Hanbal 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 group wants to use banana covers because it contain some kind of fibers that carrying Serotonin. the Serotonin is very effective in removing the black from teeth
