- Two densities can be combined to give an overall density.
Keywords
Density - The density of a substance is measured as the substance's mass per unit of volume.
Common misconception
Pupils understand they multiply by 100 when converting m to cm, but when converting m^3 to cm^3, fail to recognise the need to multiply by 100^3.
Illustrate a 1m^2 square and the equivalent 100cm^2 square, calculating the area and allowing pupils to see the equivalence of 1 m^2 = 10 000 cm^2. Also apply this to a 1m^3 and 100cm^3, thus allowing students to see 1m^2 = 100 000 cm^3.
