Primary 1 have been finding out about weight in terms of heavy and light. Everyone had the chance to compare two objects. They then used a two pan balance to be able to identify which object was heavy and which was light.
Primary 2 used the two pan balance and non arbitrary units such as cubes and pegs to balance a range of objects. Everyone had a turn to take part in the measuring activity. The children were really good at guessing which was going to be the heavier or lighter of the two objects.Learning Activities, P1, P2
