In this activity, learners build mini catapults using paint paddles and a spoon. Use this activity to introduce learners to forces and projectile motion.

This lesson guide includes six simple and quick activities to help learners better understand Bernoulli's Principle.

In this activity, learners explore moving air and the physics of lift and drag by constructing homemade wind tunnels.

In this two-part lesson, learners discover how large bodies of water can serve as a heat source or sink at different times and how proximity to water moderates climate along the coast.

In this activity, learners separate the components of Gatorade using a home-made affinity column.

In this activity, learners explore how civil engineers solved the challenge of moving water via irrigation.

In this lab (Activity #1 on page), learners explore how we see color.

Cool off in the heat with this project! Learners use simple materials to build a fan that runs on a motor.

In this activity, two groups of learners create two separate landform models out of clay (mountains and valleys).

In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.

In this technology activity, learners build simple circuits, design soft circuits using conductive thread, and then sew switch-activated circuits.

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.

In this activity, learners explore how engineers work in a team to solve problems.

In this activity, learners explore how rescue devices are designed to aid professionals during emergency situations.

In this activity, learners explore how engineering has impacted the manufacturing of canoes over time, including the development of new, durable, and lighter materials.

In this activity, learners explore the concept of how engineering solved the problem of human/computer interface.

In this activity, learners construct a device that allows them to look over ledges or around corners.

In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

In this activity, learners explore how hot and cold water move. Learners observe that temperature and density affect how liquids rise and fall.

In this activity, learners explore sound by constructing an instrument using some metal pipes, rubber bands, and a baseboard.
