What a learner can do afterwards

  • Heft two objects and say which is heavier/lighter
  • Use a simple balance to compare the weight of two objects
  • Describe one object as 'heavier than' another

The lesson

You can compare how heavy things are. Pick up one thing. Pick up another. Feel which one is heavier.

<
Six blocks are heavier than two blocks. More blocks, more weight.
Try it together

Mia holds a bag of apples in one hand. She holds a feather in the other hand. The bag feels heavy. The feather feels light. The apples are heavier than the feather.

Good to know

A balance can help too. The heavier thing makes its side go down.

Heavy things are harder to lift than light things.
