These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Explain why a long molecule has a higher melting point than a similar but shorter molecule.

• Recognise that a polymer molecule can be made up of thousands of atoms....

Sodium alginate is one of the structural polymers that helps to build the cell walls of plants like brown seaweed and kelp. It can be extracted for a wide range of uses. Alginate is a common food additive, E400, used as a thickener, stabiliser and gelling agent. Calcium alginate (a cross-linked polymer) is used in...

The initial frame of the video shows a toy pony. As time progresses additional ponies are added to the scene. At the end, all of the ponies are taken away. The challenge is to graph the number of ponies in the frame against time. The resulting graph is one with discontinuities.

Ponies in frame video...
