Just how simple are simple machines?
Our resource makes these machines simple to teach and easy to learn. Understand that work is when a thing moves in the direction that a force is acting on it. Conduct an experiment with first-class levers to study distance and force. Explain how a wheel and axle can be used as a lever. Identify the three different kinds of pulleys. Find the resistance force when walking up an inclined plane. Figure out the direction of the effort force when using a wedge to split a log. Explain how a screw is a kind of inclined plane. Visit a hardware store to find as many simple and complex machines as possible. Aligned to the Next Generation State Standards and written to Bloom's Taxonomy and STEAM initiatives, additional hands-on experiments, crossword, word search, comprehension quiz and answer key are also included.
