Simulations

Things you can pull, drag and break. Each simulation works on a phone and maps to a topic in the school science & maths curriculum.

How a mask filters

Let's tweak the mask's filter mesh size and see what happens.

adjust the coefficients and watch the atom counts on each side meet, and see why an equation must balance.

dip a metal into a salt solution and see whether it displaces the other metal, discovering the reactivity series.

mix two solutions and watch the ions swap partners, with the insoluble pair settling out as a precipitate.

run a reaction and watch heat flow out or in as the thermometer rises or falls, seeing what exothermic and endothermic mean.
