Alchemy is an idea based on superstition and philosophical global traditions spanning hundreds of years. Alchemists made medicines and pharmaceuticals from the earth’s materials and purified objects through philosophy, magic, and spirituality. Chemistry is based on the material principles of mixed bodies, and spans all natural or physical sciences in its practices. This book on alchemy and chemistry shows the scientific method at work and proves and disproves the subjects at hand. It explores a branch of modern science or a major scientific milestone, comparing and contrasting it with an older idea that has been proved wrong or fails to meet the strict and studied standards of science.

We say that the sun "rises" in the morning and "sets" at night, but is it really moving? Readers will learn about the long, sometimes dangerous struggle to discover whether the sun revolves around Earth, or Earth around the sun, and find out what scientists now know about our planet''s place in the universe.

Ethology is the scientific study of animal behavior. It was widely thought that animal play, mostly in mammals, was part of Darwinian natural selection and somehow fit into survival of the fittest. However, animal researchers believe that animals play out of pure joy, rather than aiding in their survival. This jovial book about animal play, tells the secrets of, and the science behind, clever baboons that know which cars to break into for snacks, mighty elephants that grieve, tricky octopuses that squirt water, and beetles that read messages through their feet. This book includes explanative text by award-winning author Rebecca Stefoff and an extensive bibliography. Key scientific terms and phrases are explained and includes procedures for scientific observation.

In this jovial book, award-winning author Rebecca Stefoff tells us not just that animals are intelligent, but explains how researchers have discovered how smart they are. Readers will learn the languages of chimps and the mental maps of birds as well as the disputes that have arisen over the years about the very idea of animal intelligence.

Can animals feel empathy or have a consciousness? Through the extensive work from ethologists like Charles Darwin and Jane Goodall, it is widely thought that some animals do feel empathy. Research is ongoing, however, dogs, birds, elephants, rodents, and dolphins are thought to all have a moral compass. In what ways do these animal species show empathy or feeling? Through explanative based text by award-winning author Rebecca Stefoff, your readers will be challenged to notice animal behavior in a myriad of ways. Key scientific terms and phrases are explained and step-by-step guidance for scientific observation procedures are included.

In the nineteenth century, over half a million men, women and children traveled west on the Oregon Trail. Stretching two thousand miles from Independence Missouri, to the Pacific Northwest, the Oregon Trail was the longest overland route used in the westward expansion. Crossing mountains and deserts, fighting disease, short of both food and water, pioneers endured many hardships to follow the trail west with their hopes and dreams of seeking fortunes in the unsettled west. Author Rebecca Stefoff traces the roots of the Oregon and California Trails back to the seventeenth century, telling the stories of those who left the security and comfort of their homes, to endure months of hard travel in the hope of a new life.
