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.

Balance the Equation

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.

break a number down branch by branch until every leaf is prime, and see its unique prime factorisation appear.

enter two numbers and see the shared primes make the HCF and all the primes make the LCM, with the product rule falling out.
