In this hands-on activity, learners build their own kaleidoscopes and explore how light can reflect of off surfaces such as mirrors, to produce beautiful patterns.

Learners explore the Bernoulli effect by building an airfoil (airplane wing) and making it fly.

In this activity, learners will turn an ordinary tray of sand into a desk-top garden for meditation.

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

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

In this activity, learners are challenged to create a parachute using easily sourced materials in order to transport a LEGO figure safely to the ground.

In this activity, learners make a Benham Top to explore visual illusions and optics.

In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

In this activity and/or field trip, learners investigate the water currents that aquatic animals create when they breathe, feed, and propel themselves through water.

In this bilingual (English/Spanish) activity, learners create family trees by tracing the hands of their family members.

In this dynamic activity, learners build a catapult that launches projectiles, such as marshmallows.

In this activity, learners use maps to locate the Northwest Coastal region.

In this activity, learners will observe birds in their backyard or local park. They will attempt to find common Ohio birds and will look for bird behaviors just like an ornithologist.

In this group activity, learners make multi-sided polygons with string.

In this optics activity, learners explore why the sky is blue and the sunset is red, using a simple setup comprising a transparent plastic box, water, and powdered milk.
