Learners design and build a device that can pass above a surface and detect magnetic fields. This resource includes a challenge video, leader notes, and handouts. Two supplemental videos are included: 1) Measuring Magnetic Fields and 2) NASA flight... (View More)

Students will test various materials to determine if any can shield their "magnetometer" (compass) from an external magnetic field using their own experimental design. If no suitable material is available, they will devise another method to protect... (View More)

In this activity students investigate cloud opacity, including transparent, translucent, and opaque cloud characteristics. The activity is a companion resource to an episode of the PBS series, SciGirls. The episode, titled "SkyGirls," featured NASA... (View More)

The lithograph features illustrations, statistics and science goals of the James Webb Space Telescope. The accompanying classroom activity prompts students to use the images and text to generate questions about the telescope. Students then research... (View More)
