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.

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

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 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.

Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

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

In this activity, learners string a line across the room and build cable cars that can move from on end to the other.

Use this model to demonstrate the goal of NASA's Kepler Mission: to find extrasolar planets through the transit method.

In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.

In this Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat

In this activity, learners build cars using syringes and water-powered hydraulics. Learners construct the car frame out of cardboard and set up a hydraulic system to raise and lower the car.

In this activity, learners build a paper model of the spacecraft and photometer (telescope) used during NASA's Kepler Mission.

Learners explore the field of civil engineering by making a bridge using spaghetti as their primary building material.

In this Bob the Builder(TM)-themed activity, learners explore what it means to work together as a team.

In this activity, learners will engineer a water irrigation system. Learners will create a ditch irrigation system -- or an acequia-- to move water with the help of gravity.

This activity introduces learners to the structure and properties of carbon nanotubes.

In this activity, learners consider how a simple machine, a lever, turns a small push or pull (a small force) into a larger--or stronger--push or pull (a larger force).
