In this activity, learners create night lights using a plastic cup, programmable PICO Cricket, tri-color LED, and sensor.

In this activity, learners use clear nail polish to create a beautiful iridescent pattern on black paper. Learners discover that a thin film creates iridescent, rainbow colors.

In this activity, learners explore sound by constructing tube zithers, stringed instruments from Southeast Asia and the South Pacific.

In this activity, learners transform everyday milk into small plastic figurines and jewelry. Use this activity to introduce learners to monomers and polymers.

In this activity, learners construct a model of DNA to better understand the structure of DNA and protein synthesis.

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

In this activity, learners build a musical drum using a cardboard tube, plastic wrap, and beads.

In this activity, learners explore how pens have been engineered and re-engineered over time. Learners work as a team to develop a working pen out of everyday items.

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 discover that nanoparticles of gold can appear red, orange or even blue. They learn that a material can act differently when it’s nanometer-sized.

In this activity, learners will explore the ways natural materials can produce sounds. Appropriate for any age, learners can make individual music or create a symphony with others.

In this activity, learners discover that it is difficult to trace a curve by using its reflection in a mirror. Use this activity to discuss how the brain works.

In this activity, learners design and build a Zoom-a-rang using everyday materials. Experiment with different materials and Zoom-a-rang designs to see how they fly.

In this activity, learners will build a model of a nebula using cotton balls and colored water. Astronomers photograph nebulas and add colors to provide information about the nebula's composition.

To understand how skaters turn in midair, try this little experiment! Individuals can do this activity alone, but it works better with a partner.

A design challenge that takes paper airplanes into an entirely different direction: a magnus glider uses cups and and rubber bands to create a glider that uses the same forces that a curveball (from b

In this activity, learners thread gumdrops together to make a model of a polymer.

In this activity, learners will write a secret message that only their friends will be able to read.

In this activity, learners will construct an air cannon as a model for the human ear.
