Delia Arciniega wrote about a simple machines scavenger hunt, identifying examples of six simple machines - wedge, wheel and axle, lever, inclined plane, screw, and pulley. Bikes, office chairs, hammers, ramps, screws, and pulleys were provided as examples that make tasks easier by redirecting or multiplying applied force. The document discusses how each machine simplifies common motions like lifting, cutting, and moving objects vertically or horizontally.
