In this activity (page 59 of the PDF), learners spin and observe false eyelashes in jars of water (prepared at least 1 day ahead of time) to investigate the effects of different types of motion on the

In this activity on page 15 of the PDF, discover how materials and physical forces behave differently at the nanoscale.

In this activity, learners make their own flip book that shows real solar flares erupting from the Sun in November 2000. Step-by-step instructions are included with photos.

In "Exploring the Solar System: Mars Rovers," participants learn about how scientists and engineers use robotic rovers and other vehicles to explore distant worlds, and experience some of the challeng

An outdoor scavenger hunt helps learners consider the theme of "What Is Life?" Learners explore what living organisms are, including how organisms meet basic needs of food, shelter and water to surviv

In this activity on page 15 of the PDF, learners measure the amount of bubbles that they make using a detergent.

Space Guess Quest is a fun game that encourages participants to identify the many types of objects in space, from human-made spacecraft to nebulas, galaxies, stars, and worlds.

In this activity, learners explore a surprising method for calculating the mathematical constant pi, known as Buffon's Needle.

In this activity, learners use food scraps from the kitchen to grow new vegetables.

In this physics activity (page 8 of the PDF), learners will make their very own working compass.

Using a vertical wind tube and using simple materials, individuals and groups attempt to design a "satellite" that floats for at least 5 seconds.

In this chemistry demonstration, learners observe a chemical reaction that produces a colorful effect.

In this activity, learners will explore the dynamics of air pressure by using a candle, a cup, and a dish of water.

Learners build simple catapults and use them to launch cotton balls.

In this activity, learners will build a design and build a place for pollinators to drink from.

In this activity, learners use a nail and magnet wire to build an electromagnet, which controls the movements of a paper dancer.

Just like birds, some dinosaurs had air-filled (pneumatic) bones, which made the dinosaurs' skeletons lighter.

This activity (on pages 38-43) has learners simulate the way scientists track and map the movement of otters in the wild using radio trackers.

Visitors mix water and sodium bicarbonate (baking soda) in a large flask. They then add citric acid to the mixture and stopper the flask. The resulting reaction creates carbon dioxide gas.

Visitors separate a mixture of pebbles, salt crystals, and wood shavings by adding water and pouring the mixture through a strainer.
