Hands-on experiments introduce natural and manmade structures such as a bird's nest and skyscraper and such structural elements as arches, domes, trusses, and beams
Ideal for science fairs and curriculum projects, each title in this series contains ten science experiments each followed by a two-page spread explaining the scientific principle covered in the previous experiment.
Explains the properties of air through experiments which feature such topics as what air is, how much force wind has, what shape is best for flying, and how sound travels.
Explains the need for standard units of measure and suggests simple experiments that demonstrate the use of these units in measuring distance, volume, and weight.
With clear text and easy-to-find supplies, these experiments invite readers to explore the scientific principles of sound, which include finding out what kinds of matter conduct sound, locating the sources of sound, and matching vibrations.
A step-by-step guide for creating a variety of projects suitable for entry in a science fair with suggestions for choosing a subject, performing the experiment, and polishing the presentation.
Packed with activities, these books put scientific ideas into practice in a fun way. Each experiment is accompanied by clear, photographic step-by-step instructions. Graphics indicate difficulty level and time required to carry
How quickly does your hair grow? How long does it take to react to a command? Can you measure time with water? There are so many things to measure in the world around you. The concepts introduced in this book will help you perform exciting and fun experiments. Some will even give you ideas for your science fair. Using simple materials, you can do everything a scientist does: conduct experiments, keep records, and draw conclusions from what you have learned. You will then be ready to discover the world of time!
