Get ready with teaspoons, a measuring jug and some water!

This experiment will answer the question – can you trust a teaspoon to give you the right dose of medicine?

By measuring the capacity of your spoons we shall investigate how much variety there is, and discuss if this is an issue in cookery and medicine.Kit required: Each group of students (by table?) will need one measuring jug with a 200 ml marking, an additional container of water, some teaspoons (ideally different shaped ones), cloths to mop up spillages and paper/pencil to write down results.
