Rusting: A Form of Oxidation
Pupils observe and record the corrosive nature of oxidation-reduction reactions, and determine the electro-chemical series of selected metals.
Curated OER
Flower Pigments
Pupils experiment with Thin Layer Chromatography to separate pigments found in flower petals.

Getting the Minerals Out
Students explore the tissues of the bone. They discuss bone composition and physiology. Students perform experiments to compare and contrast the decalcifying properties of several liquids.
Curated OER
Testing for Conductivity
Students test the conductivity of selected liquids and solids. They test the circuit by touching the two free ends of the wires together and add salt little by little recording the data after each addition. Finally, students predict...
