Hi, I have been told that we are going to have a cross curriculum event in September, on or around Roald Dahl day. The theme is George's marvellous medicine, and the English department want some teacher demos that mix things together in a similar way to George, as well as student practicals. They want these activities to involve as many as possible of the 5 senses. The students will then use their experiences to help with pieces of writing. Brainstorming with the HoD, we are thinking - elephant toothpaste, conc acid and sugar, and possibly methane bubbles or glycerine/potassium permanganate Then vinegar/lemon juice with calcium carbonate and UI (for colour changes) and possibly adding some spices, and maybe custard balls? Do you have any good thoughts or good ideas for this? It will be for year 7.
