In this activity, learners work with an adult to build a rocket and launcher out of a plastic 2-liter bottle, flexible plastic hose, plastic tubing, toilet paper tube, and duct tape.

In this two part activity, learners become draft detectives by constructing their own draft catchers to detect drafts around windows or doors.

In this activity, learners construct a simple game to test their hand-eye coordination and steadiness of hand.

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

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

Visitors mix urea with water in one flask and mix calcium chloride with water in another flask. They observe that the urea flask gets cold and the calcium chloride flask gets hot.

This is an activity about motion, power, air and Newton’s Third Law of Motion, which states that for every action there is an equal and opposite reaction.

In this activity, learners build an old-fashioned paddle boat out of simple materials.

Learners will build and experiment with their own windmills made from simple household materials.

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 physics activity (page 10 of the PDF), learners will explore how energy from moving water can be used.

In this activity, learners construct a traditional handicraft toy that illustrates a motion commonly associated with violins and earthquakes.

In this physics activity (page 8-9 of the PDF), learners will explore wind energy. They will build their own windmill and see how energy from wind can be converted into a useable form.

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 activity, learners build a mini crank machine to make a bird "fly." This engineering activity introduces learners to automata, rotational motion, cranks and cams.

In this activity, learners build styrofoam boats powered by twisted rubber bands.

In this activity, learners build a racecar using only a rubber band, spool, straw, and paper clip! This racer is a classic toy that zips across a flat surface.

Learn about friction and kinetic energy with this cool spinning toy.

In this physics activity, challenge learners to make a rubber band-powered spool racer. Demonstrate principles of motion as well as potential and kinetic energy.

In this activity, learners build a mini dancing robot. This engineering activity introduces learners to electricity, circuits, switches, conductivity, and motors.
