                                                                 Course Purpose

 

The purpose of this course:

 

1.                   Is to introduce the 8th grade students to mechanical drawing through the use of orthographic sketching and CADD.

 

2.                  Is to give the students an introduction to aerospace technology through the construction and subsequent launching of a compressed air and water, pop bottle rocket.

 

3.                  Is to introduce the students to electrical theory and principles.

 

4.         Is to introduce the students to internal/external engine theory and cover the basic 4-stroke cycle and 2-stroke cycle engine nomenclature, and how the parts of an engine interact with each other.

 

                                                               Course Objectives

 

To help the student:

 

1.                   Develop skills and methods that will allow each to produce simple orthographic drawing that follow standard drawing procedures and guidelines. 

 

2.                  Visualize objects and the draw them in an orthographic projection format.

 

3.                  Assign the proper dimension to the proper place on a drawing according to standard drawing procedures. 

 

4.                  Gain the necessary computer skills to navigate throughout our architectural CADD and mechanical CADD programs.


 

5.                  Develop and extend a practical knowledge of Newton’s third law of motion.

 

6.                  Develop and extend a practical use of algebra and geometry.

 

7.                  Gain a working knowledge of compressed air systems.

 

8.                  Develop and extend a working knowledge of aerodynamics.

 

9.                  Understand sound scientific methods for changing variables in an experiment.

 

10.              Develop and understand why precision is important in fitting the parts of a  project of this type together.

 

11.               Write a formal report using the APA format assigned to technical scientific writings.

 

12.              Gain an understanding of basic electrical principles. (ie. theories of magnetism, law of attraction and repulsion of charges, static and current electricity, AC and DC current)

 

13.              Gain a working knowledge of the three basic parts of electricity, (Voltage-Current-Resistance) and how they interact with each other.

 

14.              Understand electromagnetism and how it is used in our everyday life.

 

15.              Read and interpret simple electrical schematic drawings.

 

16.              Be able to do Ohm’s Law calculations for series and parallel circuits.

 

17.              Mathematically calculate the power usage of appliances and then calculate the cost to operate these appliance for specific amounts of time. 

 

18.              To be able to step-up and strep-down transformer calculations.
