Introduction
This book is a collection of science experiments designed to show you that science is more than a list of
facts—science is fun! The 201 experiments in the book take science out of the laboratory and put it into
your daily life.
Science is a way of solving problems and discovering why things happen the way they do. How does a
battery work? Why is Venus so hot? How can a frog build a nest in a tree? You'll find the answers to
these and many other questions by doing the experiments in this book.
The experiments cover five different fields of science:
• Astronomy The study of the planet we live on—Earth—and all our neighbors in space.
• Biology The study of the way living organisms behave and interact.
• Chemistry The study of the way materials are put together and their behavior under different
conditions.
• Earth Science The study of the unique habitat that all known living creatures share—the Earth.
• Physics The study of energy and matter and the relationship between them.
The Experiments
Scientists identify a problem, or an event, and seek solutions, or explanations, through research and
experimentation. A goal of this book is to guide you through the steps necessary to successfully
complete a science experiment and to teach you the best method of solving problems and discovering
answers.
1. Purpose: The basic goals for the experiment.
2. Materials: A list of necessary supplies.
3. Procedure: Step-by-step instructions on how to perform the experiment.
4. Results: An explanation stating exactly what is expected to happen. This is an immediate learning
tool. If the expected results are achieved, the experimenter has an immediate positive reinforcement. An
error is also quickly recognized, and the need to start over or make corrections is readily apparent.
5. Why? An explanation of why the results were achieved is described in terms that are understandable
to the reader who may not be familiar with scientific terms. When a new term is introduced and
explained, it appears in bold type; these terms can also be found in the Glossary.
You will be rewarded with successful experiments if you read an experiment carefully, follow each step
in order, and do not substitute materials.
