Students identify simple machines in everyday tools and settings. Part A corrects three sentences about scissors, an axe, and a flagpole, each assigned to the wrong machine type. Part B has four fill-in-the-blank questions about inclined planes, wheel-and-axle components, and what a wedge does. Part C has three true-or-false statements about wheels and friction, wedge shape, and pulley direction.

Connecting machines to real tools makes the six types memorable and relevant to daily life.
