Just how simple are simple machines? 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. 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. Aligned to the STEAM initiatives and Next Generation Science Standards, each concept is paired with hands-on activities and experiments.
