In this activity about the solar system, learners use various light sources to examine ice with different components to understand how NASA studies planets and moons from space.

In this game, learners match descriptions of marine debris (shoes, batteries, paper towels, etc.) to images of these items.

The Drawing Board consists of a marking pen that remains stationary and a platform that swings beneath the pen, acting as a pendulum.

In this activity, learners take on the role of a carbon atom and record which reservoirs in the carbon cycle they visit.

In this activity (Page 22 of PDF), learners investigate the evolution of wheat by washing different types of dough with water and comparing the results.

In this activity, learners are introduced to challenges of maintaining temperatures while living in space.

In this activity, a group of learners work collaboratively to design and construct a paper model showing the evolution of an environment through multiple stages, from prehistory through the modern cit

This simulation of laparoscopic surgery enables learners to practice and to learn this modern surgical technique.

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 geology and engineering activity (page 7 of the PDF), learners build an earthquake simulator, then use it to test various building designs, exploring different materials, shapes, and design op

In this interactive board game, learners "hire" different types of scientists to help canine character Ruff Ruffman solve unusual problems.

In this outdoor activity, learners use a mapping technique to become oriented to the major features of an outdoor site.

Learners work in groups to build model cars from paper parts. First, each learner builds cars individually and the group times themselves.

In this math lesson, learners identify the relationship between the number of sides in a regular polygon and the number of struts needed to make each polygon rigid.

In this activity, learners explore color, light and shadow by creating their own puppets to hold in front of a light source.

This paper describes a working-model demonstration of Ernest Rutherford's 1911 experiment about the nature of atoms.

Working in small groups, learners receive a written scenario regarding a bacterium with a certain goal it must carry out.

In this outdoor activity, learners search for the warmest and coolest, windiest and calmest, wettest and driest, and brightest and darkest spots in an area.
