I Used to Know That: Science: Fascinating Truths About How Animals Evolve, Plants Grow, Molecules Bond, and Stars Explode (Blackboard Books)

I Used to Know That: Science covers the many facets of the modern scientific world including the general principles of physics, chemistry, and biology and explains how they affect our everyday lives.Do you know why we are able to see light and hear sound? What is the Earth made of? How does the body produce energy? And, most important, does any of this matter? In I Used to Know That: Science, Marianne Taylor will answer those questions and more and will tell you why the answers are vital to us and to the scientists working on the cutting edge of scientific research. In this book, you will learn about: Physics-Energy and Electricity: How electricity is generated; how heat moves from one place to another; the relationship between electricity and magnetismForces: The four fundamental forces; the origins of the universe; the composition and behavior of planets, stars and galaxies; the basic laws of mechanical physicsWaves, Radiation and Space: How waves behave and how they affect us; the electromagnetic spectrum; radioactivityChemistry-The Periodic Table: How to read the table; how atoms work; chemical bonds and reactionsFuels, Air and Pollution: Chemicals, both helpful and dangerous, in the air; crude oil and its useful chemicals; live cycle assessmentsMetals: The Earth’s structure; metals and alloys; construction materialsOrganic Chemistry: Natural polymers and their usefulness; nutrition; which chemicals are harmfulBiology-Human (and Other) Bodies: The body’s systems-circulatory, skeletal, muscular, nervous, digestive, reproductive, respiratory and sensoryCell Biology: The structure of a cell; how photosynthesis works; what hormones doEvolution and Environment Ecology: The origins of life; how the eukaryotic cell evolved; mutation and natural selection; population, predation and extinctionGenetics: what chromosomes are; how you inherit genetic traits; reproduction and cloning I Used to Know That: Science is a necessary read for anyone who wants to understand the modern scientific world and how the general principles of physics, chemistry, and biology affect our everyday lives.
