Bring in a heavy suitcase. Show the children that it is difficult to lift and carry because it is really heavy. Ask if they have ever carried anything heavy? Ask the children to discuss what could be inside. Scribe ideas for what could be inside the case.
Challenge: Write or draw a picture of what you thought could be inside the case.
Children may already have some experience of weight through carrying heavy and light items. Can we make a table of heavy and light things we have carried in the past?
Challenge: Draw a picture of one heavy and one light object you have carried in the past.
Encourage children to make direct comparisons holding items to estimate which feels the heaviest. Why do you think that? How could we check? Model language of heavy, heaviest, light, lightest to compare items starting with items which have an obvious difference in weight. (a can and a bean bag, a block and a feather etc.)
Challenge: Upload a photo of you holding one heavy and one light object in each hand.
In order for children to not to think that bigger items are always heavier, weigh some small, heavier items and some large, lighter ones. (eg a can of beans and a blow up ball) Explain the size doesn’t always mean the heaviest/lightest.
Challenge: Upload a photo of you holding a small heavy object and a light big object.
Model using marbles, pennies etc to show how much something weighs. A feather may only be one penny, but a wooden block could be 5 pennies. The bigger the number of the pennies the more it weighs.
Challenge: Can you record the results? How many pennies did they weigh? Can you order some objects from heaviest to lightest?
- Can you cut and sort the items into heavy or light?
- Can you order the items from heaviest to lightest?
