Lesson Title: Lab on SIMPLE MACHINES: LESSON 5 OF 7 |
||
|
This lesson involves having the student, working in small groups, complete a hands-on lab demonstrating knowledge of the simple machines inclined plane, pulley, wheel and axle, and the lever. The student will also be shown compound machines or pictures of compound machines to identify simple machines that these machines include. |
||
|
INSTRUCTIONAL GOALS |
The student will be able to complete laboratory tests involving the inclined plane, pulley, wheel and axle, and the lever. The student will be able to calculate the mechanical advantage of each of the machines. (showing the increase of output force of the machine compared to the input force exerted by the student in conducting the test) The student will identify simple machines found in compound machines (shown as actual machines or in pictures) |
|
|
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 |
Completion of a lab form which will include force readings obtained during the lab activity, and areas for calculating the mechanical advantage of the machine (percentage of increase in force obtained by the machine). The form will also include a section for identification of simple machines as part of simple compound machines shown. |

|
LESSON ORGANIZATION |
Opening the
Lesson: |
The instructor will demonstrate the proper methods of setting up and conducting each of the tests the students will complete, and review the procedure for calculating mechanical advantage. The instructor will also demonstrate what to look for in identifying simple machines found in a compound machine. |
|
Developing the
Lesson: |
The students will be allowed 35 minutes for completion of the lab, with constant monitoring by the instructor. |
|
|
Closing the
Lesson: |
The instructor will review the the completed tests and give approximate results obtained at that time. The instructor will review the simple machines the students should be able to identify in the compound machines. |
