In this activity, learners will experiment with the physics of flight by making a gliding contraption with strange looking wings. The activity explores flight with connections to the natural world.

In this physics activity, challenge learners to lift a book with just air using a plastic bag and a straw. This activity demonstrates compressed air and forces.

Take the two-straw challenge and discover how pressure affects vacuums! In this activity, learners experiment with drinking through one and two straws, comparing the amount of liquid they can drink.

In this chemistry activity, learners witness an exothermic reaction, while making their very own, completely usable sidewalk chalk. This is also an excellent activity for exploring color mixing.

In this activity, learners explore density, convection, stratification, and, by inference, the melting of icebergs. Learners make hypotheses, test their hypotheses, and explain their observations.

In this activity, learners with explore the gases present in air. They will then build their own wind cannons and challenge family and friends to a friendly competition.

During this hands-on activity, learners are briefly exposed to moviemaking and animation, when they create their own thaumatropes.

This is an activity about circular motion. Learners will explore the laws of motion and force by observing circular motion.

In this yummy chemistry activity which requires adult supervision, learners use sugar and water to explore how crystals form.

“Exploring the Universe: Orbiting Objects” is a hands-on activity that invites visitors to experiment with different sized and weighted balls on a stretchy fabric gravity well.

This is an activity about Newton's First Law of Motion - a body in motion tends to stay in motion, or a body at rest tends to stay at rest unless acted upon by an outside force.

In this quick activity (page 1 of the PDF under SciGirls Activity: Music and Sound), learners will construct an oboe-like instrument from a plastic drinking straw by cutting the end to split it into t

In this activity, learners will explore the physics of air by making a snake kite.

In this hands-on activity (on page 2 of the PDF), learners experiment with lemon juice and paper to create a message that can only be revealed using chemistry.

Using household materials, learners can make white gooey globs from clear solutions. Alum, dissolved in water, reacts with the hydroxide in ammonia to create aluminum hydroxide.

Learners compare the properties and solubilities of Styrofoam (TM), ecofoam packing peanuts, and popcorn. First, the solubility of each substance is tested in water.

This is an activity about reaction times. Just how quickly must an NHL goalie respond to save a shot, and how does your reaction time compare?

In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.

In this math activity, learners pretend there is a special store that lets you pay for toys by their weight in pennies.

Create an instrument that you don't play--you just listen to it through tubes of various lengths.
