Mass and weight

This is a lesson that I have used with year 5 pupils to help them understand the difference between mass and weight. When I teach it I use myself as the example in the “how much does and average woman weigh?” question but I have changed it for a stock picture here. Pupils will need to use bathroom scales to find their mass and then calculate their weight on earth, in space and on the moon. There is an option to use “Bob’s” mass if they prefer.
