Inventions andthe Scientific Process
A Classroom Lesson from The MathScience Innovation Center
Inventions and the Scientific Process Where do ideas come from?
How do you know if an idea is good (or not)?
How do scientists develop and test their ideas?
Why Learn About Inventions? It’s fun!
It relates science to YOUR daily life.
They’re unique; we remember the strange and different…
… so we can tie methods of inquiry and science to the study of inventions!
Some Inventors and their Inventions… Note how each happened
Think about the characteristics of each inventor
Think how the scientific method relates to the process of invention
Benjamin Franklin 1706-1790 The “Franklin”
The Glass Harmonica
Did he “invent” electricity?
Friedrich Kekule’ 1858 Wanted to be an
architect, not a chemist!
Kekule’ StructuresInstead of H2O,
H – O -- H
Galileo 1564 - 1642 17 years old
Saw swinging lamp in church
Thomas Edison 1876 Simply worked all
the time (Genius is 1 % inspiration and 99 % perspiration)
By accident – and keen observation --invented phonograph!
Albert Einstein 1905 Used pencil,
paper, & his mind – NO LABS!
Knew by “feeling”
General Theory of Relativity
Elijah McCoy 1872 Mechanical
Engineer and Train “Oilman”
Invented the automatic lubricator for engines
“The Real McCoy”
Alexander Graham Bell 1876
Interested in “Visible Speech” & the deaf
Knew little about electricity – so he invented telephone
Founded the National Geographic Society
Art Fry 1974 3M Scientist… … & choir
member Developed the
Chester Carlson 1938 Invented
electrostatic photocopying method
IBM, RCA, GE, and other companies turned him down
Jack Kilby 1959 Worked for Texas
The Integrated Circuit

How do Inventions Happen? Close observation Sheer dumb luck – timing Motivation -- $ ? Search for an answer to a problem Creative approaches and strategies By asking, “what if?” and Brainstorming Using “models”… followed by a period of testing or scientific
Traits of Inventors Unique – different individuals
Risk-takers – follow their instincts
Ask questions -- & pay attention to answers
Inspired – passion about subject
Task commitment – persistence
Which of these traits do you have?
Inventions:are PRODUCTS we create which are… Unusual
Appropriate for a job
Transformed from something else
Condensed (refined after testing)
Pathways to Inventions First, find a PROBLEM that you want to
Develop your IDEA.
Then, TEST your idea.
And finally, you will EVALUATE your results.
Finding Your ProblemMake a “bug list” of things that
What “bugs” you? What can you improve? Messy room? Pencils that break? Heavy school backpacks? Little brothers or sisters?You can come up with an idea from your bug
Developing Invention IdeasUse Synectics (analogies)
Compare your idea to another thing, or even to yourself!
How is ______ like a ______ ?
How am I like a ______?
More Ways to Develop IdeasCombine
What is exactlyopposite to myidea that I couldsomehow combinewith it?
And More Invention Ideas!Use the SCAMPER Method:For my idea, what can I …. Substitute Combine Adapt Modify – Magnify – “Minify” Put to other Uses Reverse or Rearrange … to make it WORK!

Put Your Idea to THE TEST!Once you have an idea, then put
your idea to the TEST to see if it works!
In other words, design a test to see if your hypothesis for your invention is supported (or not)!
The Process of Invention and Science An idea (or problem) = hypothesis
Develop a “bug” list = observe/describe
Build/design = testing
“Back to the drawing board” = rethink hypothesis and try a new variable
Establish criteria to evaluate = analysis of results
Will the public buy it? = conclusion
More Invention Strategies Change your perspective Work problems backwards Break your own rules for past success Develop new reading habits Be a “risk-taker” Combine opposites Listen! Listen! Listen!
Once begun is half-done!
“If I have a thousand ideas a year, and only one turns out to be good, I’m
