Light Waves This kid-friendly introduction to the physics of light covers the basics of solar energy, the electromagnetic spectrum, photon particles, light scattering, and reflection and refraction. Readers will follow along as two children and a cow in a lab coat learn how light works in realistic and imaginative scenarios.
Simple Machines: Wheels, Levers, and Pulleys Machines make work easier— helping break things apart, lift heavy objects, and change the power and direction of force applied to them. In this accessible picture book, celebrated nonfiction author David A. Adler outlines different types of simple machines—wedges, wheels, levers, pulleys, and more—and gives common examples of how we use them every day.
Magnets Push, Magnets Pull Trusted children's nonfiction author David A. Adler covers the basics of magnetism, including compasses, for aspiring scientists. Hands-on experiments are smartly woven into the narrative. Want to test out the strength of a magnet? All you need is a bowl of water and some paper clips!
Anna Raff's lively art illustrates scientific concepts clearly, with the added fun of two siblings and their dog exploring and learning together. Back matter includes a glossary that defines such terms as attraction, pole, electromagnetism, force, and more. Suggested activities on how to make your own magnet are also included.
Things That Float and Things That Don't It can be surprising which objects float and which don't. An apple floats, but a ball of aluminum foil does not. If that same ball of foil is shaped into a boat, it floats! Why? And how is it possible that a huge ship made of steel can float? Answering these questions about density and flotation is David A. Adler's clear, concise text, paired with Anna Raff's delightful illustrations. Activities that demonstrate the properties of flotation are included.

《光的故事》本书向孩子介绍涵盖了太阳能和光谱，以及光的散射、反射和折射的基础知识。读者将跟随两个孩子和一头穿着实验服的奶牛学习光线在现实和想象场景中的工作原理。
《简单机械不简单》本书介绍了不同类型的简单机械——楔子、坡面、杠杆、滑轮等等——并给出了我们每天如何使用它们的常见例子，要知道，机器使工作更容易。《磁铁推推，磁铁拉拉》本书介绍了磁性的基础知识，包括指南针和磁力、磁极、电磁学等术语，艺术清晰地展示了科学概念，让孩子同两个小孩和他们的狗一起探索和学习。
《沉下去，浮上来》本书用简洁明了的文字回答了这些关于密度和浮力的问题：哪些东西是可以浮动的，哪些不能？苹果可以漂浮，为什么铝箔球不能？如果把同样的箔球做成船的形状，它就会漂浮起来!
