Project Guidelines And Materials

3rd Quarter Physics Project: Simple Electric Motor (SEM) Guidelines: 1. GROUPING a. Students will work with a partner (dyad). b. Working alone is allowed. 2. MATERIALS a. Students will provide their own materials. b. A list of the materials needed for the SEM project will be provided. c. The materials for the SEM project should be complete and must have the correct specifications as indicated in the list of materials. They are also allowed add-ons. d. Groups with incorrect, incomplete or no materials will not be allowed to make the project; they will automatically get ZERO (no project make ups)! 3. PREPARATION a. The materials in the list must be purchased before the scheduled project making date. b. Students may practice ahead of time. They can refer to the how-to videos posted online and read the procedure in advance. c. A rubric scoring guide will also be given ahead of time to students so they may refer to it from time to time when they make their prototypes. 4. EXECUTION a. The schedule will be posted in the Physics Laboratory (Room 3002/3003) and through Maimar Rola; it will also be announced by the teacher b. The students must be present on the scheduled date they are to execute the project; in case of absence, students must present an excuse letter for consideration. His/her partner must be present and reason valid to be excused. c. There will be no other schedule for project making other than the date given to their class. d. Venue for the project execution is the Physics Laboratory or their classroom during their Science class period. e. It will be an on the spot project making and presentation. f. Students will be given 30 to 40 minutes to finish the project then their output will be evaluated right after. 5. EVALUATION a. A scoring rubric (given earlier to the students) will be used to assess the final project output. b. Students must submit the rubric to the teacher for the project evaluation right after they finish. c. Dyads without scoring rubric will not be assessed (since the rubric is in the list of materials) and hence get ZERO. d. The finished project should have the best quality and functionality.

3rd Quarter Physics Project: Simple Electric Motor (SEM) Here’s the list of the materials and tools you need to make the SEM project. Please put in mind that you are discouraged to spend too much; be resourceful in acquiring the materials, if there’s no purchase needed then do not buy anymore. Be creative in your presentation (the look and feel of the final output); you may put add-ons i.e. switch or etc… Practice and be sure you have a working prototype and most of all, have fun! ;)

Take note of the following variables*: •

• • •

• • •

diameter/thickness of the wire number of loops/windings (for the wire coil) shape of the coil (circular, oval or flat) size of the coil (big or small diameter) size, shape and number of the magnets diameter of the copper wire number (or voltage) of dry cells

You only need a very small sheet. When you buy, share with other groups. This is a part of the materials. Do not lose this otherwise you will not be graded or allowed to make the project. Present after the project execution for immediate assessment. If you want, you may include a switch for your motor.

Extra credit will be given for successful integration.

Be creative. You may also include other add-ons. Your creativity and imagination is the limit! You’ll also need: Scissors, long nosed pliers, battery holder/case, and wooded board (5”x10”) for the base.

*These are things you might want to experiment on to get a better working final output than your current prototype. Try playing with these variables by adjusting their values and see for yourself if you get better results! Enjoy! ;)
