In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.

This activity (on page 2) explores how sensing is part of robotics. Learners try tying their shoes with different constraints.

Learners explore magnetism and motion as they build a simple marble run. Learners test different arrangements of plastic and cardboard tubes, bottles, and cups on a magnetic board.

In this activity, learners build small animated toys that move.

In this activity, learners build a figure that moves and "comes to life" when they pull its string.

In this hands-on activity, learners use an assortment of (mainly household) items to complete Rube Goldberg-type challenges.

In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

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

Learners follow the template to build and fly a paper helicopter.

In this activity, learners will build ramps and test how the laws of physics apply do different objects. Learners will explore physics and cause and effect through this activity.

In this fun and, at times, hilarious force and motion activity, learners will use household objects to build a crazy contraption and see how far they can get a tennis ball to move.

In this activity, learners make mobiles to explore the concepts of balance, counterbalance, weight, and counterweight.

In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.
