Simple Machines WebQuest for Mr. Braun’s 7th grade Technology Students Lagrange Middle School

Introduction For the mechanical gears unit you will need to know the simple machines This webquest will give you an introduction to simple machines Your task will be to identify all of the simple machines and then find real world examples for each.

Task This is a group assignment. Find one partner and work in groups of two. You will identify all of the simple machines You will create a PowerPoint explaining the function of each simple machine You will bring in an example of each machine for class Create one mechanism

Procedure Find a partner Identify all six simple machines using the internet then: Create a PowerPoint with the following slides Title Table of contents One slide per machine Reference slide Each machine slide must have: Machine name Description of machines function Picture of the machine Find one real world example of each machine Present your real world examples to the class Use two or more machines to make a mechanism

Correctly identify all simple machines Evaluation Grade out of 100 points Correctly identify all simple machines 15 points PowerPoint 50 points Each machine slide with be worth an equal portion of the 50 points. You will lose points for having no picture, no description of the machine, or a poor or inaccurate description. Mechanism 15 Points Presentation 20 You will receive an equal amount of points for each item you are suppose to bring it. Any item not included will result in lost points

Conclusion Now that you have research and presented real world examples of simple machines we are going to begin our mechanical gear unit. This unit will include many of the machines you have research and also show why it was important for you to make a mechanism. Each of the mechanical gears will create one mechanism, your task will be to make one mechanism using all of the simple machines.

Page for Teachers This project is meant for three-five 40 minute class periods. Two-three for research and PowerPoint creation. Two-three for presentation depending on hour large your classes are. This lesson can stand on its own, you do not have to have a mechanical gears unit after. You could use it as an introduction to a Rube Goldberg assignment or other problem solving activity.
