Outcomes
Specification References
- 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
Starter
Main Body of Lesson
- 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.
Plenary
- Here is the old Buried Treasure activity from Vince Robinson.
Homework
- Read pages 16-21
- Q's 1-9 pg. 17
- Q's 1 and 2 pg. 19
- Extension Q's 1 and 2 pg. 20

Skills Addressed
Safety/Hazards
- A tank with water in it will be heavy and so is only to be moved by the technician; please refer to the Manual handling section of the Laboratory Lessons Health and Safety Risk Assessment
- When using springs goggles must be worn
- The main risk is from the vacuum pump and apparatus. The specific risk assessment must be read before using the apparatus.
- General Laboratory Health and Safety Risk Assessment
Notes
- None
