In this design challenge activity, learners build a tower that’s at least 12 inches high with two or more parts that move (spin, sway, or flap) in the wind.

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

String Thing is an interactive online game in which learners change a virtual string's tension, length, and gauge to create different musical pitches.

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 design challenge activity, learners build a four-stringed instrument that can play a tune.

In this outdoor water activity, learners explore evaporation by painting with water and tracing puddles. Learners will discover that wet things become dry as the water evaporates.

Make your own "Dance Dance Revolution" dance pad! In this design challenge activity, learners work in teams to build a dance pad that lets you use your feet to sound a buzzer or flash a light.

In this activity, learners make some music by constructing a kazoo out of a simple plastic drinking straw. Use this activity to explore sound, vibrations, and music.

In this activity, learners play a trick on their own brain to see if the brain can learn to ignore distracting input. Colors and words are used to play the visual trick, known as a Stroop Test.

In this activity, learners construct drums out of everyday containers (like bowls or food containers) and shrink wrap. Learners use a hair dryer to affix and tighten the shrink wrap to the container.

In this engineering activity, young learners investigate multi-level buildings.

In this engineering activity (page 2 of PDF), young learners investigate how a wide base can make a building more stable. Learners use blocks or boxes of different sizes to construct stable towers.

In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.
