Performance Task:
|
|
|
There are six simple machines: lever, wedge, screw,
inclined plane, pulley, and wheel and axle. Throughout history, man has
made products and other more advanced machines which combine two or more of
these simple machines. Your task is to design and build a product that uses
as many of these six simple machines as possible, and that has application
to the real world. State the use of the machine and identify the materials
that you need to build your product.
Obtain these materials and then build
the product. In your science journal, write a brief report about how you
performed the task. Describe your final product, discussing its design,
use, and problems encountered. Explain how you overcame these problems. You
will give a demonstration of your completed device to the class.
Note to
teacher: This activity could also be done using a group of 3-5 students.
