Learners investigate weight by building a spring scale. They observe and record how it responds to objects with different masses.

In this math activity, learners pretend there is a special store that lets you pay for toys by their weight in pennies.

In this math activity, learners pretend there is a special store that lets you pay for toys by their height in pennies.

Learners examine collisions between two skateboards carrying different masses. They learn about conservation of momentum in collisions.

Learners build at least two different spinners (tops) to investigate how mass distribution, size, and shape affect the length of time the spinner spins.

In this activity, learners build a LEGO® structure while wearing mittens. This activity shows learners how difficult it is to build small things when your tools are too big.

In this activity, learners try to put together toy bricks—wearing oven mitts on their hands! This activity shows learners how difficult it is to build small things when your tools are too big.
