Students apply simple machine knowledge to real-world examples. Part A has nine fill-in-the-blank problems about a seesaw as a lever, a flagpole pulley, and an axe as a wedge. Part B is a matching activity pairing four machines — wheel and axle, screw, inclined plane, and lever — to their everyday applications.

Grounding each machine in a real example reinforces identification and prepares students for the harder reasoning questions ahead.

★ Part A: Fill in the Blank
Write the missing word or number on each line.
1) A seesaw at the playground is an example of a lever.
2) A pulley helps you raise a flag to the top of a pole.
3) An axe blade pushes wood apart because it is a wedge.
4) A jar lid works like a screw because it has spiral grooves.
5) A doorknob turns around an axle to open the door.
6) Sliding a heavy box up a ramp uses an inclined plane.
7) A crowbar helps pry open a lid by acting as a lever.
8) Simple machines do not reduce the total work, but they reduce the force needed.
9) A nail is a type of wedge that holds pieces of wood together.
★ Part B: Matching
Match each item on the left to the correct answer on the right.
