Students identify correct simple machine names and basic facts. Part A asks them to fix three sentences that misname machines — including a seesaw called a pulley and a ramp called a wedge. Part B has four fill-in-the-blank problems about how simple machines change work, the number of types, and the fulcrum. Part C presents three true-or-false statements about levers, inclined planes, and screws.
Correcting misidentifications at the easy level builds accurate vocabulary before students encounter all six machines.

Simple Machines
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
A seesaw is an example of a pulley.
Rewrite: A seesaw is an example of a lever.
2. Fix the sentence:
A ramp is a type of wedge that helps move heavy objects up.
Rewrite: A ramp is a type of inclined plane that helps move heavy objects up.
3. Fix the sentence:
A doorknob is an example of a screw.
Rewrite: A doorknob is an example of a wheel and axle.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. A simple machine makes work easier by changing the amount of force needed.
2. There are six types of simple machines.
3. A lever is a bar that turns on a fixed point called a fulcrum.
4. A pulley is a simple machine that uses a rope and a wheel to lift heavy loads.
Part C: True or False?
Read each statement. Circle True or False.
1. A lever helps lift heavy objects by using a fulcrum.
True False
2. An inclined plane makes it harder to move objects to a higher place.
True False
3. A screw is a type of inclined plane wrapped around a rod.
True False
