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

In this activity, learners will construct a measuring device (snake "string") to improve their observation skills.

In this activity, learners are challenged to calculate their own weight on various planets using a scale and calculator. Older learners may be challenged to do so without using calculators.

In this activity, learners of all ages can become food scientists by experimenting with flour and water to make basic pasta.

In this activity, learners play a game similar to Hangman by guessing a secret phrase to understand how computer scientists measure the amount of "information" in a document.

In this activity, learners play a card game that explores different size scales--macro, micro and nano.

This simple activity uses paper and scissors to convey two key concepts to learners: the nanoscale is very small and working on the nanoscale requires special tools.

In this activity, learners hook up a hair to a lever system and create a hair hygrometer to measure changes in humidity.
