PART – 1 ASTRONOMY
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.
4. Observe. If your results are not the same as described in the experiment, carefully read the
instructions, and start over from the first step.
5.Measurements
Measuring quantities described in this book are intended to be those commonly used in every kitchen. When
specific amounts are given, you need to use a measuring instrument closest to the described amount. The
quantities listed are not critical, and a variation of very small amounts more or less will not alter the results.
