... about Electricity

 The projects below are samples from previous years.  They are presented as ideas and are not required.  Notice these are all projects from one topic: electricity.


Guidelines:

            The primary objective in this project is for students to demonstrate understanding of principles of electricity by building a small device that uses electricity to perform its function [requirement in this EXAMPLE - not Science Knights requirements].

      In this project:

1.            Grading will be based on:

a.   Student following timeline of project including submitting proposed construction to teacher (5%)

b.   Student selected challenging project based on ratings below (10%)

c.   Function of construction (40%) Construction must be original and not salvaged.

d.   Original diagram of construction (5%)

e.   Understanding of how project works (20%)

f.   Presentation (20%) Students may elect to not do the presentation but their maximum possible grade will be 80%. Demonstration and presentation will illustrate the principles that cause their construction to “work.”

2.            Project must be selected by the end of class on January 19, 2005. and selection must be submitted in writing to teacher on that day at the beginning of the class period.

3.            Construction and diagram are due on Tuesday, February 22, 2005.

 

Suggested Construction Options:

Some of the projects listed below have web sites with building information.  For the ones without a website you will need to research your construction independently.

Build a model house  (Challenge level = 5)

…with 3 rooms.  Each room should have a single lamp/bulb
											and all rooms must be wired to the same 1.5 dry cell. All lamps must be
											in parallel to each other.  Two of
											the lights should be operated by single switches in their respective
											rooms.  [A switch in a room should
											operate only the light in the room in which the switch is found.]  The third light should be operated by a
											2-way (sometimes called a 3-way) switch. All switches must have only two
											positions and may be built or purchased.
