Title: How to Make Something Simple...Hard
Description: Students will have completed a unit of forces and motion prior to the current unit of study on simple machines (lever, inclined plane, screw, wedge, pulley, wheel and axle). Students will review the functions and examples of simple machines and view example Rube Goldberg machines. Students will create a compound machine out of all six simple machines to complete a simple task of their choosing. The machine should meet the limitations given in the rubric and be able to be demonstrated at school. Students will complete a PowerPoint slide show about the history of Rube Goldberg machines and write an expository essay about their finished machine.

Title: What Floats Your Boat?
Description: In this Science NetLinks lesson, the second in a three-part series on ships, students use what they have learned about ship design (along with some additional information on the Web about how ships are built) to design and build a small model boat, using limited materials. They then develop a procedure to determine the load line for their boat while it is in '' calm'' waters. Finally, they test their boat in '' rough'' waters to determine whether the load line is a practical one.

How to Make Something Simple...Hard
Overview:
After studying the six simple machines, students work in collaborative groups to research and then create Rube Goldberg machines. These machines must complete a simple task by utilizing each and all of the six simple machines working together to complete this task. Students may use any materials they can find to create the machine.  Students will take digital pictures and/or video of their projects as they demonstrate them.
