This Science video introduces teachers to an investigation where children build on their knowledge of electrical conductivity and explore thermal conductivity. Begin by demonstrating how heat travels through a material using spoons and paper clips. Attach paper clips along the spoon’s handle using petroleum jelly, then gently heat the spoon with a candle.

This Science video introduces teachers to an engaging investigation into irreversible changes, where pupils explore how combining vinegar and bicarbonate of soda produces carbon dioxide gas. In this lesson, pupils will investigate whether the quantity of vinegar affects the amount of gas produced.

This Science video introduces teachers to key safety procedures for conducting heating and burning activities in the classroom. These investigations can be highly engaging, but safety must come first. Ensure at least two adults are present during the activity to supervise pupils.
