Worksheets and lesson ideas to challenge students aged 11 to 16 to think hard about matter and radioactivity (GCSE and Key Stage 3)
Not all matter behaves as you would expect. Watch this video of corn flour behaving as a non-Newtonian fluid. This can provide an interesting starting point to begin thinking about classifying materials as solids, liquids or gases.

Modelling radioactive nuclei decay using dice. Students use a dice model to consider the effect of nuclei decay on a large number of nuclei over time. In our model the dice represent individual nuclei that make up a substance called diceium. Students plot a graph to determine the half-life.
