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

In this technology activity, learners explore digital imaging and pixels. Learners "transmit" an image to a partner by creating an image on grid paper.

In this quick and easy activity and/or demonstration, learners illustrate the effect of the weight of air over our heads.

This activity (located on page 3 of the PDF under GPS: Temperate Rain Forest Activity) is a full inquiry investigation into tree growth rates.

This lesson plan provides learners with two activities to explore the connections between events in their lives and the seasons of the year.

Use this Moon Map Guide to help learners identify features on the Moon, while looking through a telescope.

In this chemistry activity (page 3 of the PDF), learners will learn about crystals by growing their very own.

In this demonstration about force and motion, learners will explore the forces that affect a pendulum A simple model pendulum comprised of a ball and string demonstrates how pendulums work as well as

In this interactive activity, learners analyze seashells to explore phylogeny and evolution. Learners identify similar and dissimilar seashells to create a phylogenetic tree.

In this activity, learners are challenged to calculate their own weight on various planets using a scale and calculator. Older learners may be challenged to do so without using calculators.

In this activity, learners explore rocketry and the principals of space flight.

In this activity, learners construct hail-proof houses using recycled materials to discuss storm readiness and safety.

In this activity, learners explore moving air and the physics of lift and drag by constructing homemade wind tunnels.

In this two-part lesson, learners discover how large bodies of water can serve as a heat source or sink at different times and how proximity to water moderates climate along the coast.

In this two-part activity, learners explore the Earth and Sun's positions in relation to the constellations of the ecliptic with a small model.

In this archaeology-related activity, learners build their own time capsule and choose a storage location and a date to reopen it.

Coins are everyday objects which tell a lot about the people who use them.

In this activity, learners will use a compact disc to build an air puck that can glide across a smooth tabletop. The puck glides with almost no friction on a cushion of air escaping from a balloon.

This activity encourages visitors to build an electroscope—a simplified version of one of the tools scientists use to study the invisible forces on Earth and in space.

“Exploring the Solar System: Pocket Solar System” is a hands-on activity in which visitors make a scale model of the distances between objects in our solar system.
