| 2 | Use a simple model of a see-saw to investigate the relationship between opposing forces. |
| 3 | Weigh a series of objects suspended in air and then suspended in water. |
| 4 | Discuss balanced and unbalanced forces on moving and on stationary objects to create explanatory diagrams using arrows to show the direction and scale of the forces involved. |
