This lesson introduces pupils to the essential practical skills needed for accurate density calculations later in the unit. Students learn how to use electronic balances with precision, calculate the volume of regular objects using mathematical formulas, and work confidently with standard scientific units such as grams, kilograms, cubic centimetres and millilitres.

Clear modelling, step‑by‑step worked examples and scaffolded practice ensure pupils build secure confidence in the mathematical and practical foundations required for density work in Lessons 4–6.
