In this activity, learners act as the Earth and observe how different angles between the Sun, Earth, and Moon affect the phases of the moon we see each month.

In this activity, learners build a miniature wind tunnel to measure force. Learners construct the model out of Lexan plastic, a fan, and a precise digital scale.

This is a classic exercise for visualizing the scale of the Solar System.

In this activity, learners work in teams build and launch rubberband-powered foam rockets.

Learners work in groups to design and build a tower out of balsa wood. As a motivator, they can compete to build a tower with the highest strength-to-weight ratio.

In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about

In this activity, learners cut out and fold their own collapsible origami starshade, an invention that shields a telescope's camera lens from the light of a distant star so that NASA scientists can ex

In this activity, learners engineer a paper helicopter that spins to the ground when dropped.

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

In this activity, learners will explore how light can refract or break apart into different colors.

In this activity (pages 42-49), learners discover the methods and challenges of building nanoscale structures with macroscale equipment.

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

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

In this activity, learners make a model of a pollution spill that occurred at Bangs Lake in Mississippi and measure water quality parameters in their model.

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.

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

In this activity, learners explore how engineering has impacted the development of bridges over time, including innovative designs and the challenge of creating bridges that become landmarks for a cit

In this activity, learners make a 3-D model of magnetic fields by inserting a small, strong magnet into a sphere.
