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 math lesson, learners determine and compare the rate of descent of various learner-constructed parachutes. Learners construct parachutes that will have maximum hang times.

Learners will construct a model of a heart valve using a film canister, a piece of masking tape, and a piece of paper.

In this two-part activity about the connection between the lupine plant and butterflies, learners first read "Miss Rumphius," a storybook about lupine by Barbara Cooney.

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

In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.

In this math lesson, learners design an experiment to model a leaky faucet and determine the amount of water wasted due to the leak.

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 string a line across the room and build cable cars that can move from on end to the other.

Using simple materials, learners will construct the end effector (grasping device) of a robotic arm and use the device to capture and pick up an object.

In this activity, learners watch a video to learn about a couple who built a home out of shipping containers in Brooklyn, New York.

In this activity, learners make and test fly paper helicopters. Learners use templates to create paper helicopters and then take take turns flying them in the air.

In this activity, learners work in teams to build and test paper airplanes. Learners try to fly their airplanes directly on the runway and earn points for accuracy.

In this activity, learners build styrofoam boats powered by twisted rubber bands.

In this quick activity about pollutants and groundwater (page 2 of PDF under Water Clean-up Activity), learners build a model well with a toilet paper tube.

In this math activity related to volume, learners use problem solving skills to calculate and build a model house for Minus the dog.

In this activity, learners build bridges out of newspaper and tape to explore how structures are designed to bear loads.

In this activity, learners build a mini dancing robot. This engineering activity introduces learners to electricity, circuits, switches, conductivity, and motors.

In this activity, learners explore how engineers have improved roofing designs and materials in order to protect the contents of buildings.
