Learners build a model of a pollution control device--a cyclone. A cyclone works by whirling the polluted air in a circle and accumulating particles on the edges of the container.

This lesson will helps learners answer the question: How does the bombardment of micrometeoroids make regolith on the moon?

In "Exploring the Solar System: Mars Rovers," participants learn about how scientists and engineers use robotic rovers and other vehicles to explore distant worlds, and experience some of the challeng

This activity (located on page 3 of the PDF) is a full inquiry investigation into mapping the underground “plumbing” of geysers.

This activity (on page 2 of the PDF under SciGirls Activity: Doghouse Design) is a full inquiry investigation into absorption and reflection of radiant energy.

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

Based of the The Tech Challenge 2015, learners will engage in two mini-design challenges related to seismic engineering.

In this hands-on activity, learners use the steps of the design process to create a hook to rescue a "space capsule" from the water.

This quiz lets you estimate your annual radiation exposure.

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 (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

In this online game, learners attempt to send a rocket ship to various targets. Learners can adjust the angle and thrust of the rocket before it is launched.

In this online Flash game, learners take to the skies in a hot air balloon and are challenged to beat other balloonists' times to the finish line without crashing.

In this activity, learners build a simple solar oven out of household materials to melt chocolate and marshmallow between graham crackers--known as s'mores.

In this technology activity, learners explore digital imaging and pixels. Learners "transmit" an image to a partner by creating an image on grid paper.

In this activity about archaeology, learners will explore different Egyptian hieroglyphs and recognize their meanings and uses.

Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.

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 explore rocketry and the principals of space flight.

In this activity, learners construct hail-proof houses using recycled materials to discuss storm readiness and safety.
