Experiment
Teddy bear weighing and measuring
- ages 3–9
- 40 min
Maths activities: comparing, measuring, and weighing stuffed animals.
Steps
- Children line up their teddy bears from smallest to largest.
- They measure them with a tape measure or blocks and record the result in a table.
- They weigh the bears on a balance scale and determine which is the heaviest.
- Older children draw a bar chart of the bears' heights.
Tip: For preschoolers, concepts like bigger-smaller, heavier-lighter are enough.
Materials needed
- Balance scale for children (1 per group)
- Tape measure (1 per 2 children)
- Measuring blocks (e.g., 2 cm cubes) (1 set)
