Challenges of Astronomy in a unique collection of thirty astronomy experiments ranging from ancient astronomy to cosmology. Each of the experiments contains one or more challenges for the reader. The progression is from the Earth outward through the solar system to the stellar and galactic realm. Topics include the shape of the sky, Stonehenge as a stoneage abacus, determination of the size of the Earth, the distance of the Moon and planets, Kepler's laws, planetary mass and density, the temperatures and atmospheres of planets, the speed of light, the distances of stars, the nature of the quiet and active Sun, photometry and spectroscopy, stars clusters and variable stars, fundamental properties of stars, and Olber's paradox.
Challenges of Astronomy is a translation and extensive revision of a German-language resource book for secondary school teachers of science. Physical science teachers will find this edition too a rich resource of experiments to their own milieus, but it is suitable for many other English-language readers too, from northern and southern hemisphere locations. The beginning experiments are suitable for bright high school and non-science major university students while the later experiments which offer increasingly difficult challenges are more suitable for sciences majors. Amateurs with a variety of skills will find this hands-on book entertaining, informative, and useful.

How can you help children with moderate to severe autism become more effective communicators? Discover the Visual Immersion System (VIS), a practical, research-based intervention framework that taps into the strong visual processing skills many children on the spectrum have. You'll learn how to use readily available resources - from photos and symbols to apps and software - to create a customised system of visual supports that boost seven key communicative functions. For each of the functions, you'll get comprehensive how-to guidance on choosing tools and materials, conducting systematics instruction, collecting data, and assessing how well interventions are working. A must for SLPs, interventionists, and educators, the innovative VIS approach will ensure better communication and higher quality of life for children with autism. Why The VIS Works Uses visual supports, an approach that's proven successful for children with autism Strengthens communication skills needed for learning and meaningful human interaction Builds on evidence-based assessment and intervention procedures developed over decades at Boston Children's Hospital Incorporates a wide range of low-tech and higher-tech options Flexible - can be used in home, school, or community settings provides clear, easy-to-use instructions on conducting interventions Includes guidance on generalising new communication skills
