In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.

This activity (on page 3 of the PDF under GPS: Baseball Activity) is a full inquiry investigation into how "bounciness" relates to the distance a ball will fly when hit off a batting tee.

In this activity, learners simulate taking HIV antiretroviral drugs by using Tic Tac mints and Kool-Aid packets.

In this activity, learners explore the economics of coal mining as you they use fake money to purchase mining tools, attempt to carefully mine their cookies, sell their chocolate chip ore, and try to

In this activity learners observe mold growth on different types of bread by measuring and recording the growth rate.

This activity (on page 2 of the PDF under SciGirls Activity: Pet Handedness) is a full inquiry investigation into whether pets show a preference for the left or right paw, or “handedness” like people.

In this activity related to nanotechnology, learners observe some of the effects that result from creating a thin layer of material several nanometers thick.

This is an activity about the adaptations that allow the Aye-aye to survive in its habitat. Learners will explore how the Aye-aye collects food and how this is influenced by their specialized finger.

In this activity, learners try pouring water out of a regular cup and a miniature cup. It’s harder than it sounds! Learners discover that different forces dominate at different size scales.

In this activity, learners construct drums out of everyday containers (like bowls or food containers) and shrink wrap. Learners use a hair dryer to affix and tighten the shrink wrap to the container.

Before there were clocks, people used shadows to tell time. In this outdoor activity, learners will discover how to tell time using only a compass, a pencil, a handy printout, and a sunny day.

In this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.

In this health activity, learners explore breathing, lungs and asthma. Learners test their lung capacity by blowing air into balloons.

In this activity, learners explore how parachutes are used to slow down moving objects. Learners work in teams of "engineers" to design and build their own parachutes out of everyday items.

This is a quick activity (on page 2 of the PDF under Stained Glass Activity) about the "Tyndall effect," the scattering of visible light when it hits very small dispersed particles.

In this activity, learners use Starburst® candy to sort, classify, compare, and graph. Learners grab a handful of one-inch candy squares, sort them by color, graph the candy, and discuss the results.

In this activity, learners design and build a NASA rover using raw pasta and candy with a limited imaginary budget.

Learners explore magnetism and motion as they build a simple marble run. Learners test different arrangements of plastic and cardboard tubes, bottles, and cups on a magnetic board.

In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.

In this activity learners will plant grass seed and track the growth of the grass over time.
