Teacher resource for planning or adapting to use with pupils
- One member of the group picks up and feels the mass of two objects, e.g. a stone and a bean, one after the other. Which feels heavier? Complete the table below.
- Another member now uses the balance to compare the mass and completes the table
- Repeat this for all the objects, comparing two objects at a time, allowing each member of the group to participate.
- Pin your table on the wall and look at each others results.

|---|---|---|
