In this activity, learners will pretend to be archaeologist using this chilling experience.

In this activity (on the left side of page 5, continued on the right side of page 4 of the PDF), learners make models of colorful butterflies.

This hands-on activity shows you how to make a shaker -- a small instrument with a big sound! Fill it with beads or even pennies for a cool sound.

In this activity, learners will investigate how craters are made and the different factors that contribute to size left from the impact.

In this activity, learners will imagine the challenges and opportunities of asteroid mining.

Los jugadores toman turnos para añadir figuras de tres cuadrados a la cuadrícula. Intenten encajar sus figuras en la cuadrícula de modo que bloquee al otro jugador.

In this activity, learners explore ray optics. Learners discover that they can use a magnifying glass to create an upside-down image.

In this activity, learners make self-assembled polymer spheres.

In this activity, learners describe an object they can’t see. After someone picks outs a few mystery objects and places them in a pillowcase, learners will investigate using only their hands.

In this experiment, learners use JOY liquid detergent and glycerin to make the largest bubble they can that lasts 15 seconds.

In this challenge, learners have to figure out in what order to combine five solutions to change the color from clear, to yellow, to blue, and back to clear.

In this activity, learners investigate the properties of plastic bags. Learners find out what happens when they slowly push a pencil through a plastic bag filled with water.

In this activity, early learners simulate fossil prints in play dough or clay.

In this activity, early learners combine pre-cut recognizable shapes and their own abstract ideas to make representational pictures (e.g. houses, trees, shoes).

This is part 1 of the three-part "Crayon Rock Cycle" activity. In this activity, learners explore how sedimentary rocks form.

In this activity, learners use their estimation skills to match the unmarked containers to their amounts.

In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.

In this activity, learners will create unique rockets. Each rocket will be powered by air as the learner will blow into a straw and watch their rocket fly.

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 consider how a simple machine, a lever, turns a small push or pull (a small force) into a larger--or stronger--push or pull (a larger force).
