No Prep Plans: Cambridge Science Year 8 – Chemistry Reactivity of Metals
Metals Reactivity Experiment & Create a Reactivity Series Chart

Help students discover why some metals react more vigorously than others with this engaging, hands-on chemistry investigation! Students investigate the reactivity of common metals, observe reactions with dilute acids and metal salt solutions, collect evidence, and use their results to construct their own Reactivity Series. They then apply their understanding to explain displacement reactions and explore real-world uses of different metals.

Designed to support Cambridge Lower Secondary Science learning outcomes and suitable for Grades 6–8, this ready-to-use lesson combines scientific inquiry, critical thinking, and practical laboratory skills in an easy-to-implement format.
