Answer 1

Rube Goldberg Machine Plan:

Purpose: The purpose of our Rube Goldberg machine is to pop a balloon.

Materials:
- Marble
- Ramp
- Pulley
- Lever
- Wheel and Axle

Steps:

1. The marble is released down a ramp and into a cup attached to a pulley.
2. When the cup reaches a certain weight, it pulls down on the pulley, releasing a lever.
3. The lever then pushes a wheel and axle, causing it to turn.
4. The turning wheel and axle then releases a ball down a tube onto the balloon, popping it.

Design:

- The ramp is built at a 45-degree angle to allow the marble to gain enough momentum to reach the cup.
- The pulley is attached to a sturdy frame with a cup at the end to catch the marble.
- The lever is positioned above the wheel and axle, allowing it to easily push it and start the chain reaction.
- The wheel and axle are placed strategically so that when it turns, the ball is released onto the balloon.

Prototype:

A prototype is optional, but it can be built using cardboard, string, and other easily accessible materials to test the functionality of the machine on a smaller scale.

Final Build and Testing:

Once the final machine is constructed, test it to ensure all the components work together smoothly. Make any necessary adjustments or improvements to ensure the success of the machine in popping the balloon.

Observations and Results:

During testing, we noticed that the lever needed to be adjusted slightly to push the wheel and axle with enough force to release the ball onto the balloon. After making this adjustment, the machine worked perfectly and successfully popped the balloon. It was a fun and satisfying project to see all the simple machines working together to achieve the desired outcome.
