ou are going to build your own Rube Goldberg machine. You will start with the plan you made last time but you must add at least two other kinds of simple machines. You may use more but there needs to be at least three in your design. The purpose of the machine can be whatever you like. After you make your plan, create a design. A prototype is optional. Next build the machine. Once you have built the final machine, test it to see if you need to make adjustments or improvements. Write all your observations, steps, and test results in 2 pargraphs
For my Rube Goldberg machine, I decided to start with a pulley system to lift a small ball to the top of a ramp. Once the ball reaches the top, it will roll down the ramp and hit a domino, setting off a chain reaction that triggers a lever to release a toy car down a ramp. The car will then push a button that turns on a fan, which blows a pinwheel attached to a spinning wheel. As the pinwheel spins, it triggers a switch that turns on a light bulb. The final goal of the machine is to turn on the light bulb.
After designing and building the machine, I tested it out to see if it worked as intended. I found that the pulley system worked well to lift the ball to the top of the ramp and the chain reaction of dominoes and levers successfully released the toy car down the ramp. However, I noticed that the car was not hitting the button with enough force to turn on the fan. I decided to add a small ramp at the end of the initial ramp to give the car more momentum. After making this adjustment, the machine worked perfectly with the car pushing the button, turning on the fan, spinning the pinwheel, and ultimately turning on the light bulb. Overall, I was happy with the result and found the process of building and testing the Rube Goldberg machine to be a fun and rewarding experience.
