Résumé du livre
Developed in partnership with NASA, Invisible Universe introduces students to some of the most awesome astronomical phenomena ever discovered. Students begin by studying the electromagnetic spectrum and come to understand how astronomers study the sky by detecting invisible light. After learning the types and properties of visible and invisible light, students are ready to investigate the massive and violent waves of radiation in space called gamma-ray bursts. Where do they come from-massive black holes, colliding galaxies, supernovas, nebulae &? As with all GEMS guides, Invisible Universe was extensively tested by teachers across the country. It comes with accessible background information for the teacher and clear, step-by-step directions.Alan Gould is author of the GEMS Teacher's Guide The Real Reasons for Seasons.
