Water Absorption in Materials

The video introduces the concept of absorption, explaining how certain materials can absorb water while others cannot. Through a simple experiment using plastic cups, tissue, cloth, and rock, students learn which materials absorb more water. The video concludes with examples of other materials that absorb or do not absorb water, reinforcing the lesson's key points.
