Explores the principals of sound, light, and radiation waves, explaining how they travel and carry energy from one place to another.

This book discusses sound waves, light waves, and the full range of the electromagnetic spectrum, from radio waves to gamma waves.

Light and sound are two of the most important things in the universe. Without them everything would be dark and silent. Plants and animals would die. What scientists have found out about light and sound helps us live and work, but there is more to learn. For more information on light and sound, read Pioneers of Light & Sound, another book in the Mission: Science series.

An illustrated introduction to light and sound that covers acoustics, reflection, refraction, rainbows, and other related topics, and includes a quiz, a glossary, and a list of resources.

Science, engineering, and technology permeate nearly every facet of modern life and hold the key to solving many of humanity's most pressing current and future challenges. The United States' position in the global economy is declining, in part because U.S. workers lack fundamental knowledge in these fields. To address the critical issues of U.S. competitiveness and to better prepare the workforce, A Framework for K-12 Science Education proposes a new approach to K-12 science education that will capture students' interest and provide them with the necessary foundational knowledge in the field. A Framework for K-12 Science Education outlines a broad set of expectations for students in science and engineering in grades K-12. These expectations will inform the development of new standards for K-12 science education and, subsequently, revisions to curriculum, instruction, assessment, and professional development for educators. This book identifies three dimensions that convey the core ideas and practices around which science and engineering education in these grades should be built. These three dimensions are: crosscutting concepts that unify the study of science through their common application across science and engineering; scientific and engineering practices; and disciplinary core ideas in the physical sciences, life sciences, and earth and space sciences and for engineering, technology, and the applications of science. The overarching goal is for all high school graduates to have sufficient knowledge of science and engineering to engage in public discussions on science-related issues, be careful consumers of scientific and technical information, and enter the careers of their choice. A Framework for K-12 Science Education is the first step in a process that can inform state-level decisions and achieve a research-grounded basis for improving science instruction and learning across the country. The book will guide standards developers, teachers, curriculum designers, assessment developers, state and district science administrators, and educators who teach science in informal environments.

Chronicles the lives and work of various individuals who have created such important things as telescopes, microscopes, cameras, lasers, and MP3 players.
