15 Vocabulary Words Included
Here are the 15 words hidden inside this puzzle, along with their thematic definitions for classroom discussions:
LEVER
A rigid bar resting on a pivot used to move a heavy load with one end when pressure is applied to the other.
PULLEY
A grooved wheel with a rope looped around it used to lift heavy objects by changing force direction.
WHEEL
A circular frame capable of rotating on an axle to drastically reduce friction when moving loads.
AXLE
A central rod or shaft on which a wheel or group of wheels revolves.
INCLINE
A sloping ramp or flat surface tilted at an angle to help lift loads with less applied force.
WEDGE
A piece of wood or metal with one thick end and one sharp edge used to split or secure objects.
SCREW
An inclined plane wrapped spirally around a central cylinder used as a fastener.
FULCRUM
The fixed pivot point around which a lever pivots and balances.
FORCE
A push or pull exerted on an object that can cause it to change speed, direction, or shape.
MOTION
The continuous physical movement and change in position of an object over time.
WORK
The transfer of energy that occurs when an applied force moves an object across a distance.
ENERGY
The fundamental capacity of a physical system to perform mechanical work.
FRICTION
The resisting force that opposes the sliding motion of two surfaces in contact.
EFFORT
The input force applied to a simple machine to overcome resistance and move a load.
LOAD
The physical weight, resistance, or mass that a machine is designed to move.
3 Fun Ways to Use This Printable in the Classroom
Make the most of this worksheet with these creative lesson and activity ideas:
- Classroom Tool Hunt: After completing the puzzle, have students walk around the classroom and spot real-life simple machines (doorstop = wedge, scissors = levers, pencil sharpener = wheel and axle).
- Mechanical Advantage Sketching: Have students draw a labeled diagram of a seesaw showing the FULCRUM, EFFORT, and LOAD.
- Engineering Journal Entry: Ask students to select two simple machines and explain how they combine to make a complex machine like a bicycle.
