Learners construct and use a "real" 3D coordinate system out of balsa wood and foam core. They will then be able to locate coordinates in space.

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

In this activity, learners will explore coding by arranging words and phrases to create an order of operations in this low tech version of computer programming.

In this design challenge activity, learners build a machine out of cardboard that runs smoothly and dependably. Learners must be precise to make sure their component works properly.

In this project, students explore how levers work, by making a puppet with moving limbs.

In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.

In an investigation called "Shape It!" learners craft tiny boats out of clay, set them afloat on water and then add weight loads to them, in order to explore: how objects stay afloat in water; what th

In this hands-on activity, learners use the steps of the design process to create a hook to rescue a "space capsule" from the water.

What's a more compelling problem to solve than being stranded on a deserted island?

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

Learners design their own experiment to investigate how pollution diffuses through ground material.

Design a vessel that tests the limits of wind power given a set of off the shelf and recycled materials.

Learners design different shaped bandages for different purposes. First, they draw their designs on paper.

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

Make a model city happier with LEDs, circuits, motors, and batteries! Groups can think, discuss, design, and build what would make a community happy. Kids can work as part of a team or on their own.

In this activity, learners design a therapeutic agent to image and/or cure various diseases in the respiratory system.

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

The goal of this Star Wars activity is to design and build a balancing device to help an Ewok escape the Imperial Forces by sliding down a tightrope to safety.

Learners will build and experiment with their own windmills made from simple household materials.

In this activity, learners test and compare the physical properties of thermoplastic polymers. Learners compare different plastics based on their color, degree of transparency, texture, and density.
