TENNESSEE LESSON PLAN BUILDER
Lesson Title: Incline plane, screw, and wedge: LESSON 3 OF 7
This lesson uses a 15 minute video to introduce the simple machines inclined plane, screw, and wedge.
This lesson discusses the last three simple machines, the inclined plane, the screw, and the wedge, including examples of each, and discussing the resistance forces each overcomes.
INSTRUCTIONAL GOALS
The student will be able to name the last three of six simple machines. (the inclined plane, the screw, and the wedge)
The student will be able to list one example of each simple machine.
The student will learn what resistance force or forces each simple machine will overcome, and how to calculate mechanical advantage for each machine.
Standard Number: 1.0 Force and Motion.
SPI identify simple machines, given illustrations of machines in action.
SPI recognize the simple machines found in a compound machine, given an illustration of a machine in
action.
FORMATIVE ASSESSMENT
Verbal and written responses by students.
Questions on this material will be included in unit exam.
LESSON ORGANIZATION
Opening the Lesson:
_5_ minutes
The instructor will review the first three simple machines discussed in lesson 2.
Developing the Lesson:
_35_ minutes
The students may view a 15 minute video titled “ Work, Energy, and the Simple Machine: Inclined Plane, Wedge, Screw” available on United Streaming.
Using the textbook, study guide, and PowerPoint slides, the instructor will discuss the last three simple machines, the inclined plane, the screw, and the wedge, showing examples of each, and discussing the advantage in overcoming resistance forces such as gravity and friction, including the calculation of mechanical advantage for each machine..
Closing the Lesson:
_5_ minutes
The instructor will briefly review the machines just discussed, and discuss the upcoming lesson on mechanical advantage.
