"Simple Machines! introduces kids to the concept of mechanical advantage and harnesses kid-power by inviting them to build machines of their own design. This book also opens eyes and minds to the diversity of machines in their lives, and sparks the imagination with challenge, humor, and achievable projects"--Publisher.

"Clearly explained engineering concepts and fun, simple projects give kids ages 7-9 the chance to put their STEAM knowledge to the test! Teach kids to think like an engineer! The engaging projects in this book will encourage kids to investigate using items from around the house. Build a robot arm out of rulers; learn about jet propulsion with balloons; crush toilet-paper rolls to explore materials; and much more. Read about how engineers use STEAM...

How scientists find out how things work: First a scientist pulls together all the observations about something. Next, he or she thinks up a question that the observations don't explain. Then a hypothesis, that which someone believes to be the correct answer to the question is formed. It must be a statement that can be tested. Next, an experiment is made to test the hypothesis in which everything that happens is written down. Finally the scientist...

"Heatproof, transparent, and durable, the mason jar is a science lab just waiting to be discovered. Unlock its potential with 40 dynamic experiments for budding scientists ages 8 and up. Using just a jar and a few ordinary household items, children learn to create miniature clouds, tiny tornadoes, small stalactites, and, of course, great goo and super slime! With a little ingenuity, the jar can be converted into a lava lamp, a water prism, a balloon...

Presents over two dozen science activities demonstrating such scientific properties as forces and motion, chemical reactions, shapes and structures, and light and sound.
