In this activity, learners are asked to examine the differences between two materials in a pair.

In this activity, learners explore how wind tunnels provide feedback to engineers about the performance and durability of products such as planes, cars, and buildings.

This activity uses Jell-O(R) to introduce learners to microfluidics, the flow of fluids through microscopic channels.

Bones are stiff, which helps us lift heavy things and walk around, but they are also somewhat flexible, which lets them bend slightly.

In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

In the wild, small crustaceans known as brine shrimp live in marine habitats such as saltwater lakes.

In this activity, learners explore how engineers have met the challenge of keeping foods, liquids, and other items cool.

Your heart pumps blood throughout your body in one direction, around in a loop. In this activity, learners will make a model of one type of heart chamber called a ventricle.

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

In this outdoor activity, learners go "can fishing" and discover the kinds of aquatic organisms that live in and on submerged cans.

In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.

In this outdoor activity, learners make their own organic-rich soil. Depending on where this activity is done, learners will probably discover that their local soil is low in organic matter.
