The Engineering of Everyday Things: Structure and Function
---The Analysis of a Whole and its Parts.
Lesson Plan by Allen Berg

I am not incurious;
I like to look at things, care-fully
and understand how they work.
Observation and then description
are important tools of Science.

As you can see from the picture of the pen above,
Things have parts that make up the whole.
In this lesson, you will choose an object
and analyze its structure and function.

1. Name and define the object. (You can check a dictionary.)
The definition of an object is often its purpose.

2. Draw a picture of the object as a whole and as its separate parts.
2a. Take digital photographs of the object as a whole and of its various parts.
2b. Advanced students can use free 3-D software to produce computer-generated 3-Dimensional images. (Google’s “Sketch-Up” etc.)

3. Label each part.
Describe the material each part is made of.

4. Explain the function of each part and how it is related to the
whole object.

5. Look close-up and carefully at the object to find the name of the
country where it is made.

6. Evaluate the object:
a. Does it do the job it is supposed to do?
Rate its performance: poor__ ok__ good__ excellent__ etc.
b. What is the object’s durability?
How long does it last? Can you repair or replace the parts
or do you just throw it away?
c. What is its cost? Is this a “fair value”?
d. Would you recommend using this object? Why or why not?
e. Can you suggest improvements in its design?
List and explain your suggestions.
Provide a visual image(s) of your improved design.

7. Conclusion:
How does this object compare to similar objects, for use?
[Example of an “improved design”: the addition of a soft rubbery fingers grip… Photograph of the “improved” pen]

8. Share your Analysis with other students, family, and friends…
Be proud that you are a Beginning Engineer…
