Chemical Reactions & Conservation Challenge
A randomised Year 9 challenge where students use particle models and equations to identify reactants and products, compare atom counts, and justify why atoms are…
Chemical Reactions & Conservation Explorer
Explore chemical reactions by comparing reactants and products, tracking atom counts, and seeing that atoms are rearranged rather than created or destroyed.
Chemical Reactions & Conservation Investigation
A guided Year 9 investigation where students identify reactants and products, count atoms before and after a reaction, and explain conservation of atoms using simple…
Chemical Response Challenge
A real-world chemistry capstone where students diagnose a contaminated water sample, choose a treatment reaction, optimise reaction rate and submit a scientific…
Decomposition Reactions Challenge
A randomised challenge where students identify decomposition reactions, choose products, interpret evidence, recognise non-decomposition examples and apply atom…
Decomposition Reactions Explorer
Explore decomposition reactions as the pattern where one reactant breaks into two or more products, connecting word equations, particle models, energy input and…
Decomposition Reactions Investigation
A guided Year 10 investigation where students recognise the decomposition pattern, write word equations, connect energy input to bond breaking, use evidence and check…
Displacement Reactions Challenge
A randomised challenge where students use the reactivity series to predict displacement products, recognise no-reaction cases, interpret evidence and apply conservation…
Displacement Reactions Explorer
Explore displacement reactions using the pattern A + BC → AC + B, before-and-after particle models, reactivity decisions, no-reaction cases and atom conservation.
Displacement Reactions Investigation
A guided investigation where students spot the displacement pattern, compare reactivity, predict products, model the particle swap and check conservation of atoms.
Physical vs Chemical Change Challenge
A randomised Year 8 challenge where students classify changes, choose evidence, and correct common misconceptions about physical and chemical change.
Physical vs Chemical Change Explorer
Compare familiar physical and chemical changes through examples such as melting, boiling, dissolving, rusting, burning and reactions involving vinegar and bicarbonate.…
Physical vs Chemical Change Investigation
A guided Year 8 investigation where students classify changes, identify evidence such as gas, colour change, heat, light and precipitate formation, and explain whether a…
Reaction Rates Challenge
A challenge where students predict faster reaction conditions and justify their answers using collision frequency, successful collisions and activation energy.
Reaction Rates Explorer
Explore how temperature, concentration, surface area and catalysts affect reaction rate using collision frequency, successful collisions and activation-energy models.
Reaction Rates Investigation
A guided investigation where students run controlled comparisons and explain how temperature, concentration, surface area and catalysts affect reaction rate.
Synthesis Reactions Challenge
A randomised challenge where students identify synthesis reactions, choose products, distinguish synthesis from decomposition and displacement, interpret evidence and…
Synthesis Reactions Explorer
Explore synthesis reactions using before-and-after particle models, Pearson-style reaction patterns, word equations, balanced equations and atom conservation. Students…
Synthesis Reactions Investigation
A guided investigation where students recognise the synthesis pattern, identify reactants and products, compare particle models, use evidence and check conservation of…
