In this robotics activity, learners find ways to express emotions and feelings using only body movements, not facial expressions.

In this activity (posted on March 12, 2011), learners follow the steps to construct a spectroscope, a tool used to analyze light and color.

In this lesson plan, learners examine some of the of greenhouse gas emissions sources in their community.

In this activity, learners model directed evolution by making paper fly. Learners construct and fly paper airplanes.

In this activity (page 10), learners explore how molecules self-assemble according to forces of attraction and repulsion.

In this data activity, learners analyze data from coral reef snapshots taken by scientists at the Virginia Institute of Marine Science.

In this activity, learners construct a device that allows them to look over ledges or around corners.

In this design challenge activity, learners build a four-stringed instrument that can play a tune.

In this activity (page 12), learners explore how molecules self-assemble and how molecules must fit together, like a lock and key, in order to identify each other and initiate a new function as a comb

Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!

Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.

In this activity on page 5 of the PDF, learners compare water with artificial urine to see how urinalysis works. Learners use urinalysis test strips to test for glucose and protein in the fake urine.

In this activity, learners extract DNA from a strawberry and discover that DNA is in the food they eat.

In this activity (page 89 of the PDF), learners compare and contrast pitch and roll motions by using a Magic Carpet maze similar to one that was used for Neurolab investigations about microgravity.

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 explore how molecules must fit together, like a lock and key, in order to identify each other and initiate a new function as a combined unit.

Learners tour their school or home looking for sources of indoor air pollutants (IAPs).

Learners create a tool to measure how well they grip a wet object when their fingers are smooth versus wrinkly. Are smooth or wrinkly fingers better at holding on to the object?

In this activity about the circulatory system and space travel (on page 38 of the PDF), learners use water balloons to simulate the effects of gravity and microgravity on fluid distribution in the bod

Learners design and create musical instruments from common objects; their challenge is to create an instrument that can make three different tones.
