In this activity, learners conduct a simulation exercise related to public key encryption and try to intercept a message sent between two learners.

In this interdisciplinary activity, learners create a Space Weather Action Center (SWAC) to monitor solar storms and develop real SWAC news reports.

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

In this activity, learners explore electronic communication, the Morse Code system, and advances all the way through text messaging. Learners build a simple circuit, send messages to one another.

Use this model to demonstrate the goal of NASA's Kepler Mission: to find extrasolar planets through the transit method.

In this activity on page 4 of the PDF, learners investigate the importance of washing their hands.

In this technology activity, learners explore digital imaging and pixels. Learners "transmit" an image to a partner by creating an image on grid paper.

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 explore the concept of how engineering solved the problem of human/computer interface.

This activity (page 2) draws upon a familiar, computer-based concept related to visual resolution: pixilation.

In this activity, learners explore computer programming and the impact of computers on society. Learners build and test a program to turn a light on and off using an Arduino board.

In this activity about human interface design issues, learners help the Oompa-Loompas of a great chocolate factory solve different problems.

This activity (on page 2 of the PDF under GEMS Activity) is a full inquiry investigation into technology design and testing.

This activity (on pages 38-43) has learners simulate the way scientists track and map the movement of otters in the wild using radio trackers.

In this activity, learners experience some of the challenges of "tele-operating" a robotic vehicle on another planet when they design and execute a series of commands to guide a human "rover" through

In this activity, learners create their own weather forecast map.

This activity aims to stimulate discussion on the question of whether computers can exhibit “intelligence,” or are ever likely to do so in the future.

This activity about cryptographic techniques illustrates how to accomplish a simple, but nevertheless seemingly impossible task—making a fair, random choice by flipping a coin between two people who d

This activity explores what it means for a computer to be intelligent and introduces the topic of what a computer program is and how everything computers do simply involves following instructions writ

Whether it's the genetic code, an ancient language, or patterns of light in a distant galaxy, scientists often have to play the role of decoder.
