Heavier or lighter?

Compare the weight of two objects by holding them or using a simple kitchen scale, describing which is heavier or lighter.

Weight is how heavy something is. You can often feel it: hold one object in each hand and see which pulls your hand down more. That one is heavier.

A kitchen scale can help too. The side that goes down, or the higher number, shows the heavier object.

📋 For the teacher
Teach it (10–15 min):
  • Let your child hold two objects, one in each hand, and feel the difference themselves.
  • Use a real kitchen scale if you have one. Watching the number change is exciting for kids.
  • Point out the surprising cases: small-but-heavy and big-but-light objects break the bigger-is-heavier myth.
  • Use the words heavier, lighter, and about the same during cooking or grocery unpacking.
Talk about it:
  • How can you tell which of two things is heavier just by holding them?
  • Have you ever found something small that was surprisingly heavy?
  • What is the heaviest thing you held today?

Mastery looks like: They compare two objects by weight, using hands or a scale, and correctly say which is heavier or lighter.

Common stumbles: Assuming the bigger-looking object is always heavier; not paying attention to the actual pull or scale reading.
