“Climb aboard a roller coaster and hang on! It jerks and rattles to the top of a slope. It hovers a second before plunging into a stomach-thrilling drop. The turns sling riders from side to side. A jolting stop forces everyone backward. The ride is over.”
The physical science branch is the part of science I found most difficult in school. When I wrote this book, I had to look up so much in order to understand it before I could put it at a level for the readers to understand. My work paid off! This book required the least of any editing of the books I’ve written for this series. And I’ve come to have an interest in this subject more and more as new information comes to light about forces in atoms, space, and beyond.
Forces and Motion at Work defines, explains, and shows the nature of the effects of forces in our daily lives. Without seeing forces, examples have to show their actions and how they work. The laws of motion are described and explained, and changes in those forces are explored to show readers what they are and do. Energy of all kinds is discussed and supported by charts and captions in the book. Harnessing energy and how people use it is explained, and ways people use machines completes the book’s text.
Detailed captions add additional information to the abundant photographs. Bright charts provided more facts to keep the reader moving from one concept to the next. Several hands-on activities invite readers to try out their newly learned knowledge. Try out this book and find out first hand how fascinating forces can actually be!
Forces and motion ideas make terrific science fair projects. Sports fans will enjoy using this knowledge, too. My sons played baseball and one of them pitched. They knew more about it than I originally did as a science teacher!
Use the scientific method to write up the experiment on page 6 before reading it aloud. Then perform the activity on page 6 and record your results.
Here’s a form to write up the experiment.
