In this activity, children use common craft materials and ultraviolet (UV)-sensitive beads to construct a person (or dog or imaginary creature). They use sunscreen, foil, paper, and more to test materials that might protect UV Kid from being exposed... (View More) to too much UV radiation. Includes background for facilitators. This activity is part of the "Explore!" series of activities designed to engage children in space and planetary science in libraries and informal learning environments. (View Less)

Students are tasked with virtually designing a spacecraft to withstand the harsh environment of the Van Allen Radiation belts- the location of many communication, GPS and weather satellites. The details of the challenge, along with videos on... (View More) radiation, a materials list (including descriptions, densities, costs, and testing), and subsystems information are included.

Become a crime scene investigator! Learners model Dawn Mission scientists, engineers, and technologists and how they use instrumentation to detect distant worlds. After a briefing to build context, students explore interactions between different... (View More) frequencies/wavelengths of the electromagnetic spectrum and matter as they investigate the different ways scientists gather and understand remote sensing data, using Dawn instruments as examples. This module is organized around a learning cycle, engaging students through several experiences to activate students' prior knowledge and assess conceptual understanding, informing next steps.
