Students can test their knowledge of chemical sciences with this video by identifying materials that can stretch, bend, or twist, and to compare them.
Use this with our amazing Chemical Sciences unit, which investigates the physical changes of materials and how properties change when materials stretch, bend, twist, heat or cool.
