In this multi-part activity learners examine non-point water pollution.

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 design challenge, learners will engineer a structure and see if it can survive an earthquake they create.

In this design challenge, learners will practice empathy and design thinking skills by creating an invention of the future.

In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.

In this activity, learners explore the concept of how aerospace engineering has impacted sports, specifically exploring the design of golf balls.

In this online interactive simulation, learners will add different salts to water and then watch the salts dissolve and achieve a dynamic equilibrium with solid precipitate.

In this online activity, learners find out whether they are smart enough to survive as a plant.

This activity introduces the idea of "divide and conquer" using a fictitious but serious problem--a pair of dirty socks has accidentally been wrapped in one of the presents that Santa is about to deli

In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

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 listen to songs and decode hidden messages based on the same principle as a modem. As a final challenge, learners decode the binary messages in a music video.

This online simulation game explores the different consequences of water levels on the Columbia River in the Pacific Northwest.

This is an online game about the complexities of farming. Learners will "draw" cards and make decisions about how to take care of their farm.

In this activity, learners will engineer a roof using simple materials to protect a construction paper person from a rainstorm.

In this online interactive simulation, learners will test the pH of liquids like coffee, spit, and soap to determine whether each is acidic, basic, or neutral.
