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

Learners build pan pipes out of drinking straws by cutting them to different lengths. Then, learners make music by blowing across the straws and playing some well-known songs.

In this optics activity, learners build an animation tool to make mini movies. When you spin a phenakistascope, the pictures move so quickly that your eyes and brain can't separate the images.

In this activity, learners build rockets and shoot them into the air by stomping on the plastic bottle launchers.

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

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 construct wands that play different notes depending on information from light sensors programmed via a PICO Cricket.

In this engineering activity, challenge learners to design a car using only 3 straws, 4 Lifesavers™, 1 piece of paper, 2 paper clips, tape, and scissors.

In this math activity, learners pretend there is a special store that lets you pay for toys by their weight in pennies.

In this exploratory activity, learners experiment, observe and determine how various toys change from one form of energy to another.

Have fun with additive mixing! Observe what happens when the three primary colors of light--red, green and blue--are mixed together, resulting in white light.

Create your own spinning top, and explore color, shapes and spinning. This activity contains instructions for making your spinning top, and tips on how to design and decorate it.

In this activity, learners construct and launch rockets using simple materials and their understanding of chemical reactions.

Learners act as engineers and design mini submarines that move in the water like real submarines.

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 explore conservation of energy by experimenting with a solar cell light device.

In this physics activity, learners use square blocks to explore how towers fall. Learners attach a piece of string to the side of a block and then construct a tall tower on top of this base block.

In this activity, learners build their own sound machines and explore the interplay of motion and sound.

In this activity, learners watch a figure "magically" float up through the air.

In this activity, learners create air cannons out of everyday materials. Learners use their air cannons to investigate air as a force and air pressure.
