In this lesson, learners cut paper into very small pieces to explore the small size of quarks, the smallest thing we know of on Earth.

Using information from the My Place in Space lithograph, learners write and/or draw a postcard to friends and family as if they had gone beyond the interstellar boundary of our Solar System, into the

In this activity (located on page 2 of PDF), learners sing together a song that gives details about the dinosaur species Suchomimus (pronounced “Sook-o-mime-us”).

In this activity, learners build their own rockets from paper, coffee stirrers, and tape. Learners discover that when anything flies, air pressure is always involved.

This activity about density provides instructions for making a miniature "lava lite" with just salt, oil, water, and food coloring.

Learners construct a bracelet containing two strands of beads, which represents a double strand of DNA that codes for a gene. They match beads to the bases in a section of a chimp's DNA code.

Sound changes pitch relative to how you or the source of the sound is moving. Use this simple activity developed by the Exploratorium to experience the Doppler Effect yourself!

In this art/science/math activity, young learners are introduced to the concept of symmetry in nature.

Learners roll their fingerpads in ink pads, and then press their fingerprints onto balloons. Learners inflate the balloons to produce enlarged versions of their fingerprints.

In this activity, learners observe the hydrologic cycle in action as water evaporates and condenses to form rain right before their eyes.

In this activity, learners observe the moon each night for a month and draw their observations in a Moon Watch Log.

In this activity, learners cutout a set of shape finder templates to explore shapes in the world around them.

In this online version of the classic paper and pencil game, learners practice looking ahead to anticipate an opponent's move.

In this activity, learners imagine what the world might look like if we could build an elevator to space!

In this science and language arts activity, learners study fish anatomy and make their very own 3D paper fish.

"Exploring the Solar System: Craters" is an active, hands-on activity that demonstrates how craters form, and what they can teach us about the history and composition of planets and moons.

In this activity, learners explore the size and scale of dinosaurs. Learners listen to "The Littlest Dinosaurs" by Bernard Most to learn about the different sizes of dinosaurs.

Learners will construct a model of a heart valve using a film canister, a piece of masking tape, and a piece of paper.

In this activity, learners investigate the properties of plastic bags. Learners find out what happens when they slowly push a pencil through a plastic bag filled with water.

Conduct a simple experiment to explore how temperature changes can make things expand or contract.
