 * Explore || [[file:BIKE LAB Activity.docx]] || Students do activities with bikes and know that work is performed by applying force over distance. ||
 * Explain || [[file:SimpleMachines.ppt]] || PowerPoint of Simple machines. Simple machines have been used for thousands of year by humans. Students will learn to use these simple machines and be able to create a greater output force than the input force. The ratio of these forces is the mechanical advantage of the machine. ||
 * Elaborate || [[file:SM Elaborate.docx]] || Real life applications of simple machines. For compound machines, students should be able to list the simple machines that have been combined and where they are located, ||
 * Evaluate || [[file:SM Evaluate.docx]][[file:SM Engineering related Rubric.docx]] || Computer students' design of simple machines and presentations & a rubric. Students will use computers and find engineering applications of simple machines.Then, students will do a presentation of their work. ||
