### Today's Activities

Go to The Inventors Tools Box . Review the different kinds of machines. Continue to the Gadget Anatomy web page and complete the activity there.

1) In small groups, examine your machine in detail. Take turns operating the machine while the others watch to see how each part moves.

2) Discuss answers to the following questions:

What is the function of this machine? How many moving parts does it have? How are the moving parts connected to each other? What does each moving part do in the machine? Which parts are elements of machines?

3) Place the machine at rest so that everyone in the group can see it and distribute paper, pencils and erasers. Begin sketching diagrams of your machine. Draw the machine from your own point of view first. Later you can trade places and draw it from different points of view to show all working parts.

When the diagrams are completed, add arrows and written notes to indicate directions of motion for each part, label the elements of machines involved, and explain connections.

Choose a Design Challenge and brainstorm about how you might create a machine to accomplish the task.

Go to the virtual labs from the University of Utah. These are very good. Complete a lab with a partner

Hands-on: Create gears, belt drive and/or cam shaft

Design a Rube Goldberg machine! Continue with Design Challenge
