In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

In this activity, learners create 3D geometric shapes using straws and pipe cleaners.

In this activity, learners will create their very own constellation.

In this activity, learners create volcanoes like those they have examined on Earth and Mars through images taken by spacecraft.

This experiment is designed to illustrate how fluids, including water, have the ability to flow.

In this activity, learners make film canister rocket ships. A fin pattern is glued onto the outside of the canister, and fuel (water and half an antacid tablet) is mixed inside the canister.

This activity was designed for blind learners, but all types of learners can have a tactile opportunity to construct a karyotype, an organized model of an organism’s chromosomes, conveying the chromos

In this activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.

In this activity, learners build their own construction cranes using tongue depressors and pushpins.

In this activity, learners use molecular model kits to construct familiar molecules like lactose, caffeine, and Aspirin.

In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.

Using simple, inexpensive items, learners build and test submarine models.

In this activity, learners investigate the concepts of relative size and distance by creating a basic model of the solar system.

In this small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems.

In this activity, learners work in teams to construct human lung models from small plastic beverage bottles and balloons.

In this activity, learners will explore engineering concepts to construct a blanket fort using materials sourced from home.

No glue is needed for learners of any age to become marshmallow architects or engineers.

In this activity, learners simulate a multistage rocket launch using party balloons, fishing line, straws, and a plastic cup.

In this activity, learners plan and create a 24-foot long, two-dimensional model of our solar system, and compare and contrast the differences between planets and the sun.

In this activity, learners will explore how maps can provide information about a place and help us find our way from one location to another.
