Sure! Here’s a description of a Rube Goldberg machine consisting of 10 steps, utilizing the 6 simple machines: lever, wheel and axle, pulley, inclined plane, wedge, and screw. ### Step 1: Lever A small ball rolls off a table and lands on a lever. The lever is a simple machine that pivots at one end. When the ball hits the lever, it tips down on one side, launching a toy car on the other side off the table. ### Step 2: Wheel and Axle The toy car rolls down a ramp (an inclined plane) and hits a large wheel attached to an axle. The wheel rotates, and the motion is transferred to a connected gear system. ### Step 3: Pulley The gears turn a pulley system hanging above. As the gears rotate, they pull a string attached to a bucket that is filled with small weights. The bucket starts to rise. ### Step 4: Inclined Plane As the bucket rises, it reaches a point where it tips over, spilling the weights down an inclined plane. The weights roll down and hit another lever. ### Step 5: Wedge The lever that was activated by the weights is positioned at an angle, acting as a wedge. It pushes a small wooden block off a shelf, which falls onto a springboard. ### Step 6: Springboard The wooden block lands on the springboard, which is another lever. The force of the block compresses the spring and then releases it, launching a small ball into the air. ### Step 7: Wheel and Axle (again) The ball rolls onto a circular track made of a wheel and axle system. As it rolls around the track, it gains Ver mais
