Learners will build a lung model to understand how their lungs and diaphragm work to make them breathe.

In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

Learners explore the Bernoulli effect by building an airfoil (airplane wing) and making it fly.

Learners work in groups to construct bridges using stale marshmallows and toothpicks.

In this activity, learners build one or more edible coral polyps and place them together to form a colony.

Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

In this activity (page 2 of PDF under GPS: Alligator Habitat Activity), learners will study the adaptations different fish species have developed to survive in their habitats.

By tossing, collecting, and sorting beanbags, learners understand how the IBEX spacecraft uses its sensors to detect and map the locations of particle types in the interstellar boundary.

In this engineering activity, young learners investigate multi-level buildings.

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 activity, learners design and build a simple wind vane —one of the oldest kinds of weather tools— and use it to show wind direction.

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