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

In this activity, learners design miniature cars. Learners can create a telephone car, soccer car, merry-go-round car, or any other theme car they can imagine.

In this activity, learners create painting machines that can paint moving forwards and backwards.

In this engineering design challenge, learners animate a facial expression and make a machine (zoetrope) that plays the animation back.

In this activity, learners explore sound by constructing an instrument toy that buzzes when you swing it.

In this activity, learners build a cuica or chirping bird using straw, string, and a bottle cap. Use this activity to explore the interplay of motion and sound.

Design and create an optical illusion toy that makes two pictures appear to become one. This is called a thaumatrope and will allow the learner to investigate the phenomenon of persistence of vision.

In this activity, learners make an optical illusion toy from the 1800s to explore persistence of vision.

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

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 hands-on activity, children create their own kites that can fly indoors. Learners are exposed to basic concepts of gravity and air resistance.

In this activity, learners explore sound by constructing a simple piano out of wood and craft sticks.

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

In this activity, learners build a musical drum using a cardboard tube, plastic wrap, and beads.

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

In this activity, learners will become an engineer by designing and engineering a miniature parachute.

Learners assemble a hot-air balloon from tissue paper. The heated air (from a heat gun) inside the balloon is less dense than the surrounding air and causes the balloon to float.

In this activity, learners build a seesaw powered by magnets.

In this activity, learners investigate the reflective properties of light and mirrors as they make a kaleidoscope.

In this activity, learners build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).
