NATURAL SCIENCE - USING MATERIALS - VIDEOS

Hello again dear friends:

This post is about materials (plastic, wood, metal, glass, cotton, paper and leather). Students know the fact that objects are made of different materials and have different properties. This is the reason why I have chosen these videos. Remember, just click the pictures.

I hope you like them. Regards, Christopher.
