GCSE AQA Physics - P6.1 Density, Mass and Volume + REQUIRED PRACTICAL 5

New GCSE AQA Physics lesson on ‘Density, Mass and Volume’ written in line with new AQA Physics specification.

Lesson Outline:
Nice simple starter asks pupils to list objects in order of density. Density is then clearly explained with visual effects to provide an example with a definition. Volume is also explained with comparative visuals. This lead to density being considered with volume and then both considered to produce mass - leading m=ρV. Some review questions practice the use of this equation.
Pupils are tasked with finding the density of different objects provided by the teacher (simple shapes of common materials required). REQUIRED PRACTICAL 5
To continue the lesson the story of Archimedes and the gold crown is told featuring some key questioning for pupils. This then leads to pupils finding the density of irregular shaped objects by ‘displacement technique’ (REQUIRED PRACTICAL 5).
To further extend pupil knowledge Archimedes principle of displacement is further explored with floating objects such as ships in water, icebergs and ice on water.

Lesson Objectives:
- State and explain the properties called volume, density and mass.
- Use the density equation to calculate different properties of objects.
- Describe in detail experiments to identify an objects density.
- Explain how large objects such as ships float in water.
