Acids, Bases, pH & Neutralisation Investigation
A guided Year 9 investigation where students read the pH scale, use indicators, connect acids and bases to H⁺ and OH⁻ particles, and model neutralisation as salt and…

Chemistry · Chemical Reactions
A randomised challenge where students identify synthesis reactions, choose products, distinguish synthesis from decomposition and displacement, interpret evidence and apply atom conservation.
Start a free 30-day trial with class codes and progress tracking, or talk to us about your school's licence.
A guided Year 9 investigation where students read the pH scale, use indicators, connect acids and bases to H⁺ and OH⁻ particles, and model neutralisation as salt and…
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…
Explore chemical reactions by comparing reactants and products, tracking atom counts, and seeing that atoms are rearranged rather than created or destroyed.
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…
A real-world chemistry capstone where students diagnose a contaminated water sample, choose a treatment reaction, optimise reaction rate and submit a scientific…
A randomised challenge where students identify decomposition reactions, choose products, interpret evidence, recognise non-decomposition examples and apply atom…
Synthesis Reactions Challenge is one of the licensed interactives in The Education Universe. This page describes it; teachers use it in lessons and classes with a licence or the free trial.
