In this lesson, learners will understand the concepts behind endangered and extinct animals and develop their own conservation plan to save three endangered species.

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.

In this activity, learners will explore trends in shark populations using shark landing data from the National Marine Fisheries Service.

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

In this outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.

In this activity, learners use microarray technology to determine which genes are turned on and off at various points in the differentiation of pluripotent stem cells on their way to becoming pancreat

In this outdoor activity, learners work in pairs using their senses—especially touch—to learn more about individual trees.

In this activity, learners explore the concept of density-driven currents (thermohaline circulation) and how these currents are affected by climate change.

In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.

MarsBound! is an engineering simulation activity in which learners use realistic techniques to plan a mission to Mars.

This activity about cryptographic techniques illustrates a situation where information is shared, and yet none of it is revealed.

The Butterflies in Space Teacher's Guide uses "life in space" to encourage learners to conduct their own open-ended scientific investigations.

In this activity, learners explore the factors that tend to resist changes in pH of the ocean and why the ocean is becoming more acidic.

This game introduces learners to the scale of the greenhouse gas problem, plus technologies that already exist to dramatically reduce our carbon emissions and prevent climate change.

In this activity, learners explore how engineers incorporate biometric technologies into products as well as the challenges of engineers who must weigh privacy, security and other issues when designin

In this environmental science and data analysis activity, learners work in groups to track a Dead Zone (decreased dissolved oxygen content of a body of water) using water quality data from the Nutrien

April showers bring May flowers, but what do coastal storms bring?

In this activity, learners investigate the food, water, and space needs of common livestock animals.

In this activity, learners construct a coastal landmass from sand and add features such as tidal creeks and barrier islands.
