Straws and pipe cleaners are terrific materials for building models of pyramids and cubes.

Learners add calcium chloride to a baking soda solution and observe an increase in temperature along with the production of a gas and a white precipitate. These are all signs of a chemical reaction.

In this experience, learners use the internet to research physical details about Chihuly's Fireworks of Glass "Tower" and "Ceiling" and consider the decisions Chihuly had to make as he was planning th

Build a hydrometer (measures the density of a liquid) using a pipet or eyedropper.

In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

Put math of measurement into lining up — and make waiting in line fun. Choose a size characteristic that learners can physically compare, such as foot length or hair length.

In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.

In this activity (located on page 2 of the PDF under GPS: Temperate Rain Forest Activity), learners will identify a group of deciduous trees to study.

In this activity, learners create a map of a hidden surface using a "sounding stick" -- a technique similar to how underwater maps were once made.

In this activity, learners will decide together on a question about how far, long or high the group could reach together.

This activity (on page 2 of the PDF under SciGirls Activity: Soccer Ball Kick) is a full inquiry investigation into transfer of motion.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

This activity (located on page 3 of the PDF under GPS: Balloon Fiesta Activity) is a full inquiry investigation into Bernoulli’s principle and airplane wings.

In this activity, learners will train to improve lung, heart, and other muscle endurance as they walk a progressive, measured distance.

In this chemistry activity, learners will test the pH of various foods and household substances using cabbage.

In this activity, learners use geometry in observing the shapes and angles soap bubbles create when they join together.

In this weather activity (page 1 of the PDF), learners will construct their very own anemometer to measure wind speed.

In this math activity, learners will create a scale diagram of their backyard or other outdoor area on graph paper.

In this activity, learners will build thier own balance scale. Learners will explore weight and comparison through this activity.
