PART – 5 PHYSICS
Introduction
This is a collection of science experiments designed to show you that science is more than
a list of facts science is fun! The 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. Why does the Moon stay in orbit? How do you tell the age
of a fish? Why are there holes in bread? 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:
o Astronomy The study of the planet we live on-Earth-and all our neighbors in space.
o Biology The study of the way living organisms behave and interact.
o Chemistry The study of the way materials are put together and their behavior under
different conditions.
o Earth Science The study of the unique habitat that all known living creatures share-the
Earth.
o 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. You will be
rewarded with successful experiments if you read an experiment carefully, follow each
step in order, and do not substitute materials.
General Instructions
1.
Read first. Read each experiment completely before starting.
2. Collect needed supplies. You will experience less frustration and more fun if all the
necessary materials for the experiments are ready for instant use. You lose your train of
thought when you have to stop and search for supplies.
3. Experiment. Follow each step very carefully, never skip steps, and do not add your
own. Safety is of the utmost importance, and by reading the experiment before starting,
then following the instructions exactly, you can feel confident that no unexpected results
will occur.
