Create a painting by blowing air out of a straw. Push liquid acrylic paint around on some watercolor paper by aiming short bursts of air onto the paint puddle.

In this activity, learners practice counting objects found on patterned wrapping paper or fabric.

In this activity (3rd activity on the page), learners taste test different foods and categorize them as sweet, bitter, sour, or salty. Learners compare their results with the group.

In this activity, learners investigate the relative growth of lengths, areas, and volumes as cylinders are scaled up.

In this activity, learners calculate their water usage (in cups and galloons) during an average shower. Learners also chart and analyze water usage during showers in their households.

In this activity, learners create an optical illusion by spinning two attached cups. A round ball seems to magically appear when the cups spin.

In this quick activity, learners take a balance challenge to measure their average balance time. As they collect data, they investigate how practice and repetition improve their balance time.

In this activity, learners construct and launch rockets using simple materials and their understanding of chemical reactions.

In this math activity, learners earn "money" by completing simple tasks. Learners complete as many "jobs" as possible in a set amount of time.

This activity (located on page 8 of the PDF) introduces learners to the concept of Non-point Source Pollution--what happens when rain washes garbage and other pollutants into rivers and lakes.

This activity (located on page 3 of the PDF) is a full inquiry investigation into bird behaviors.

Learners act as engineers and design mini submarines that move in the water like real submarines.

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

In this activity, learners complete simple exercises to investigate the relationship between force, area and pressure and their effects on materials.

In this activity, learners will write a secret message that only their friends will be able to read.

“Exploring the Universe: Imagining Life” is a hands-on activity in which visitors imagine and draw an extreme environment beyond Earth, then invent a living thing that could thrive in it.

In this activity, learners investigate balance and symmetry by designing a symmetrical butterfly, using a paper cutout.

If you have 3-foot dowels and rubber bands, you can can started on this fun and open design challenge. You can make structures big and small: make it so you can fit your parent into it!

In this activity, learners explore how the pendulum has been a reliable way to keep time for centuries.

In this full inquiry activity (located on page 3 of the PDF under GPS: Kinetic Sculpture Challenge Activity), groups of learners will make predictions about which feature of a pendulum (mass, length,
