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.

In this lesson on cosmic rays, students will explain two examples of a cosmic ray detector. Includes information about student preconceptions and a demonstration that requires a geiger counter and optional access to a small radioactive source that... (View More) emits energetic helium nuclei (alpha particles), e.g., the mineral the mineral autunite, which contains uranium. This is activity two of four from The Cosmic Ray Telescope for the Effects of Radiation (CRaTER). (View Less)
