"Do They Absorb Water" Materials Around Us PPT Courseware 3

Small experimental requirements:

①The size of water droplets is the same.

②Observe the changes of water droplets from the side, and also pay attention to the changes of materials when exposed to water.

③Note and describe the observed phenomena. Such as the water absorption speed of the material, the size of the wetted surface of the material, the shape of the water droplets on the material, etc.

④ Sort the four materials according to their water absorption from strong to weak.

Think: What might be related to the material’s water absorption?

1. Tear the waste paper into pieces.

2. Put the mince into the water tank.

3. Stir evenly with chopsticks.

4. Use the paper mold to manipulate the paper: let the paper pulp evenly cover the paper mold and pick it up from the water.

Homework questions

1. Continue to collect materials and see what the water absorbency of other materials is? Communicate with classmates after class.

2. After the paper you made today is dry, use three classmates to make a beautiful paper bookmark and give it to your good friend.
