Grow your own yogurt, understand how humidity affects our hair, and use candy to learn about hunting. Science has never been more fun! In each of the 10 biology-focused projects in this book, a Background section explains the science topic at work, materials are listed, and clear step-by-step instructions are given. An Observations section helps young scientists understand their results. Several projects include science fair ideas and expanded versions of the experiment to engage readers further. A discussion of the scientific method and helpful glossary conclude the book.
