Outcomes

Students should be able to recall and use the formula for density.
Students should be able to take measurements for a range of regular objects and from these measurements find its density.
Students should understand how the volume of an irregular object can be found by the displacement method or using a Eureka can. They should also appreciate how important it is to find the mass and volume of a multiple of small identical objects such as marbles.

5.2 recall and use the relationship between density, mass and volume: density = mass/ volume
5.3 describe how to determine density using direct measurements of mass and volume

Density of Regular shapes - blocks and maybe a cylinder to challenge the more able. They can use the digital micrometer for one and a more sensitive balance. This will revise significant figures in measurements and in calculations.
They can use their values to identify the material.
You could also recap on prefixes - milli, centi, kilo along with conversions (1 ml = 1 cm3, m3 <--> cm3, g <--> kg) Conversion Questions for Density
Density of Irregular shapes using Eureka Can and Displacement Method.
Density of Water using a measuring cylinder. It is important for pupils to know the density of water is 1g/cm3 or 1000kg/m3.

Density of Regular Shapes - cubes, blocks, cylinders, digital micrometers, balance, sensitive balance, rulers, copies of density table.
Density of Irregular shapes - irregular shaped objects, eureka cans, balance
Density of Water- measuring cylinders - range of sizes, balance
Buried Treasure Activity - seven different sized platicine 'blobs' with a treasure (polystyrene ball painted gold?)hidden in two of them.
