Discover the wind's direction using bubbles, a map and a keen eye. Learners blow bubbles and note their general direction on a map, taking readings from different points around a building.

In this astronomy activity (page 3 of the PDF), learners will examine the effects of gravity on a person’s pulse and explore how gravity can differ from planet to planet.

In this activity, learners build a sled kite that models a type of airfoil called a parawing.

In this lesson that includes hands-on activities and demonstrations, learners discover that it is the tilt of the Earth's axis (not its proximity to the sun) that causes the seasons.

Did you know that a Slinky makes a handy model of earthquake waves?

In this activity, learners make a scale model of the Solar System and learn the real definition of "space." Learners use the online calculator to create an appropriate scale to use as a basis for thei

In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.

In this group activity, learners use some common objects and work together to simulate the Coriolis effect. During the challenge, learners make predictions and test different scenarios.

In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.

In this kinesthetic activity, learners will play a game with a ball to demonstrate the Coriolis force, which partly explains why hurricanes in the Northern Hemisphere rotate counterclockwise.

In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.

In this activity, learners interpret three trackways and use measurements and a formula to infer the relative speed of dinosaurs.

In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.

In this activity, learners model erosion using a clear shoebox and sand or soil.

In this engineering/design activity, learners make a kite, fly it, and then work to improve the design. Learners explore how their kite design variations affect flight.

In this kinesthetic activity that demonstrates pressure, learners act as air molecules in a "container" as defined by a rope.

In this hands-on and feet-on excursion, learners take a science walk to visualize the planet's immense size and numerous structures, without the usual scale and ratio dimensions found in most textbook

A group of learners models the Sun shining on the Earth. By rotating the Earth, they demonstrate how the Sun only shines on a portion of the Earth at a time.

In this three-part activity, learners use paper to explore Bernoulli's Principle — fast-moving air has lower pressure than non-moving air.

In this three part activity, learners explore and experiment with shadows to learn about the Sun's relative motion in the sky.
