This is to use with a unit on forces. After teaching the students about Rube Goldberg and his machines, students will get into groups to create their own machines. This is a packet which will guide students in creating their machines. Here is an excerpt from the directions:
We are looking for the team who can best show us how simple machines work. Here are some rules to let you know what we’re looking for.
• Work in teams of 3-4 people
• Design a Rube Goldberg device to complete a task.
• Use at least 3 simple machines: lever, inclined plane, wedge, screw, pulley, wheel and axle, gears
• Input (start the motion) can be one movement (push, drop, crank, pull, etc)
After you’ve built your device we need you to present it to our panel of judges. For your presentation you will need to discuss the following points:
• Introduce the team and the role each person played
• Discuss what types of simple machines the team used to complete the task
• Indicate why the team chose those machines
• If you could start again, what would you do differently
Students will use the worksheets in the packet to create their machine. These packets will be collected and count towards their final grade. After they feel they are ready, students will be given a very large piece of poster paper on which they will draw their machine to present to the "judges."
Worksheets include: brainstorming page, simple machines page (chart of which machines will be used), directions for the scientific drawing, presentation (questions and directions for each speaker in the group to ensure all participants participate), and a list of ideas of machines to create.
This is a great assignments. Every year my students love this project!
