Friendly Physical Science Textbook

Friendly Physical Science TextbookHow do pulleys make it easier to lift heavy objects? Why does a ramp make it easier to go to a higher level? How does the spring in a pogo stick allow you to jump and jump and jump again? Friendly Physical Science answers these questions (and many more) using straight forward narration and more than 300 colorful diagrams and photos. Abstract ideas are made concrete through hands-on design engineering and lab activities. Topics covered in Friendly Physical Science include: An introduction to the metric and English systems of measurement Calculation of surface area and volume of regularly and irregularly-shaped objects mass density buoyancy Forms of energy Time, speed, velocity and acceleration Newton's laws of motion Work and simple machines Classes of levers The wheel and axle pulleys The inclined plane, wedge and screw pressure magnetism Electricity and electromagnetism light sound Heat energy An introduction to chemistry Age Level = 12 and up Boo
