Observe the pictures and complete the table

Method
  • Look carefully at each picture of everyday work: water being drawn from a well, a door knob being turned, a box being pushed up a sloping plank, firewood being split with an axe, and a nut being tightened with a spanner.
  • For each picture, write what work is being done in the column headed 'Work being done'.
  • Decide which simple machine is being used for that work, and write it in the column headed 'Simple machine used'.
