This set pushes third graders to connect simple machines with the specific jobs they do best. Fill-in-the-blank problems cover skateboard ramps as inclined planes, paint-can-opener levers, corkscrews, grooved pulley wheels, hatchet wedges, and the idea of mechanical advantage. A matching section lines up axe blades, bottle caps, roller-skate wheels, and tow-truck cables with the right machine.
Finishing this work helps you reason about why engineers pick one machine over another when they design real tools.
Style:
Simple Machines
Part A: Fill in the Blank
Write the missing word or number on each line.
1. A skateboard ramp lets riders gain height by riding up an inclined plane.
2. A paint-can opener pries the lid off by working as a lever.
3. A corkscrew twists into a cork because it is shaped like a screw.
4. A pulley is a grooved wheel with a rope that changes the direction of force.
5. The sharp blade of a hatchet pushes wood apart because it is a wedge.
6. A pencil sharpener turns a blade around a axle to shave wood.
7. Mechanical advantage describes how much a machine multiplies your force.
8. An escalator is a moving inclined plane that carries people between floors.
9. A teeter-totter balances when equal weight sits on each side of the fulcrum.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
Axe blade
→ Wedge
Pulley
Bottle cap
→ Screw
Wheel and axle
Roller skate wheel
→ Wheel and axle
