In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

In this activity, learners use things from the kitchen as building materials to explore how shapes contribute to the strength of different structures.

Learners use simple materials to construct a model the Big Dipper. Learners hang the model from a doorway or ceiling and look up at it to see the constellation as seen from Earth.

In this activity, learners use colored candy to represent subatomic particles and make a model of an atom (Bohr model).

In this activity (page 4), learners work in groups to plan and build large structures using recyclable materials they have brought from home.

Learners make a mobile model of a carbon atom using clay, wire, and pipe cleaners.

In this engineering activity (page 2 of PDF), young learners investigate how a wide base can make a building more stable. Learners use blocks or boxes of different sizes to construct stable towers.

In this design challenge, learners will create their own roller coaster using household objects for the track and a marble or small ball as their cart.

Learners build a model of the planets in the solar system. In their model, the planets are spaced in their relative distance from the Sun.

In this activity, learners use design thinking to design and build their own bridge out of household materials including adhesives and/or connectors.

In this experiment, learners design and build a model room in a shoebox and furnish it with tiny furniture.

In this activity, learners explore the relative sizes and distances of objects in the solar system.
