In this activity, learners construct a projector out of cardboard to view their favorite images (such as storybook illustrations) on the wall.

In this activity (page 1 of the PDF under SciGirls Activity: Bogs), learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.

In this activity, learners will make cleaning up more fun with predictions and counting. Estimate how many things are on the floor (or table), then count as they are picked up.

In this experiment, pairs of learners explore how cold water affects circulation. The mammalian diving reflex (MDR) slows circulation when the body is exposed to cold water.

This is an activity (located on page 3 of the PDF under Butterfly Wings Activity) about how visible light is affected by tiny nanoscale structures, producing iridescence on butterfly wings, soap bubbl

In this math activity (Page 10 of the Play Ball! PDF), learners play a game of "football" and analyze the results of the game.

In this outdoor activity/field trip, learners conduct experiments to explore where dragonflies and damselflies perch or rest, and how the flies change behavior in reaction to other flies or fly decoys

In this quick activity (page 1 of PDF under SciGirls Activity: Kites), learners will witness firsthand the effects of Bernoulli’s Principle by capturing a ping pong ball in the stream of air created b

Use multiplication to help the aliens find out how much fuel they need to get their spacecrafts home.

In this activity, learners assemble large cubes to make nano-related images. Learners discover how different objects are related to nanoscience and nanotechnology.

In this activity, learners examine nanoscale structures of common things.

In this demonstration, learners attempt to get a large coin through a small hole, the size of a smaller coin.

This activity introduces learners to the structure and properties of carbon nanotubes.

This activity/demo introduces learners to aerogel, a glass nanofoam. Learners discover how aerogel is made and how well it insulates as well as learn about aerogel's other unique properties.

In this activity, learners sample a star field to estimate the number of stars in the universe.

In this math game (Page 15 of the Dining Out! PDF), learners figure discounts and/or profit increases for various food totals. Learners add decimals to $100.

This fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape.

From the Weather Watchers featured theme on the CYBERCHASE website. Learners will conduct experiments to discover how air temperature and humidity work together to make condensation, dew, and fog.

In this activity, learners explore probability with dice.

In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.
