“Can your child explain how a see-saw, a pulley on a flagpole, or the gears on a bicycle make it easier to move heavy things with less effort?”
Full guide and materials
- Activity. Recognise that some mechanisms including levers, pulleys, and gears allow a smaller force to have a greater effect
What to notice. Describe how a lever works: effort at one end moves a load at the other, with a pivot in between • Explain how a pulley changes the direction of a force and can make lifting easier • Describe how gears transfer and change the size or direction of forces
