Question 27
In this investigation, place a sturdy plank (1–2 metres long) on a fulcrum so it is evenly balanced. Mark evenly spaced points on each side using a metre stick or tape measure. Use weights of known weight. Work in groups.
In your groups, discuss your conclusions. Did the seesaw balance when identical weights were placed at the same distance from the fulcrum on opposite sides of the seesaw?
