内容简介

Elementary school students who find science mystifying, daunting, and hard to understand will change their minds when they open this book. The authors have transformed fundamental scientific principles into an exciting adventure where they discover how plant and animal life interact within the Earthas ecosystem, how energy is converted into heat and motion, how matter exists in solid, liquid, and gaseous states, how light is reflected and refracted, how magnetism and electricity are related, how the Earth revolves around the Sun, how the Moon revolves around the Earth, how different kinds of rock were formed, and how the Earthas surface has been formed and shaped over a period of many billions of years. The student-friendly text is complemented with instructive line art.
