In this two-part activity, learners map a navigation plan to get from Earth to Mars and back. In activity one, learners represent the orbital paths of Earth through dance and dramatic movement.

In this activity, learners will turn an ordinary tray of sand into a desk-top garden for meditation.

In this activity, learners will perform various investigations to understand the vestibular-ocular reflex and learn about the importance of visual cues in maintaining balance.

Through this nutrition activity (page 5 of the PDF), learners will understand—and probably be surprised by—how big serving sizes of various foods should be.

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

In this activity (on page 12 of the PDF), learners make a sundial (shadow clock) appropriate for their geographic location in the northern hemisphere and use it to tell time.

In this activity related to microbes, learners use water drops and hand lenses to begin the exploration of magnification. This activity also introduces learners to the microscope.

In this experiment, learners discover how an airfoil creates lift. Learners use simple materials to build an airfoil and test it at different angles to investigate Bernoulli's principle.

In this activity, learners explore how spring scales work and how they are used for non-exact weight measurement.

Exponga estos pósteres en el salón o déjelos donde los chicos los puedan explorar. Los chicos buscan las respuestas en libros de consulta, explorando el salón, y usando su creatividad.

In this activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.

In this activity related to microbes, learners create scale models of microorganisms and compare relative sizes of common bacteria, viruses, fungi and protozoa using metric measures: meters, centimete

In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.

In this activity, learners find Xi'an, the archaeological area in China where the Terra Cotta Army was discovered, on a map or globe and look more closely at the relationship of the warrior site to ot

The goal of this activity is to design the fastest sailboat or one that carries the most treasure.

In this activity, learners explore how engineers incorporate biometric technologies into products as well as the challenges of engineers who must weigh privacy, security and other issues when designin

In this activity learners will measure and manipulate flubber using different tools. Learners will explore volume and make observations about texture and shapes.

In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.

This activity (on page 2 of the PDF under SciGirls Activity: Earthquakes) is a full inquiry investigation into aerial imagery.
