The Creative Process 1. Formulating a
Hypothesis (plural is hypotheses ... do you hate
Greek?) 2. Discuss the Challenge coming up.

• But first ... you had a task from Tuesday
• Formulate one question for the Test 1
• (with answers) and write it down.
• Take 'em up, and discuss.

Speaking scientifically What's a Law? What's a
Theory? What's a Hypothesis?

Speaking scientifically What's a Law? ---- a
rule summarizing a bunch What's a Theory? of
observations. What's a Hypothesis?

Speaking scientifically What's a Law? What's a
Theory? a proposed explanation What's
a Hypothesis? - of some phenomenon
A hypothesis must be testable. Therefore it must
be specific. Here's our guidance

Some Terminology Independent Variable what you
can wiggle Dependent Variable what happens then?
Independent variable a knob on the mysterious
box Dependent variable How loud a noise it
makes.

Formalized Hypothesis If skin cancer is related
to ultraviolet light, then people with high
exposure to UV light will have a higher frequency
of skin cancer.

So to TEST the hypothesis, use it to MAKE
some predictions. If predictions prove
true, hypothesis is strengthened.

Examples of Bad Hypotheses

• Chocolate may cause pimples.
• Salt in soil may affect plant growth.
• Bacterial growth may be affected by temperature.
• Stoplight cameras can save lives.
• Temperature may cause leaves to change color.
• Why bad? Not clearly formulated.

18
Hypothesis A practice question

• If better grades are related to career
  advancement, then people in high positions will
  have had a high GPA.
• Identify the
• Independent variable
• Dependent Variable
• Prediction

19
Formalize these Hypotheses

• Chocolate may cause pimples. A B C D
• Salt in soil may affect plant growth. E G H J
• Bacterial growth may be affected by temperature.
  KLMN
• Stoplight cameras can save lives. PQRS
• Temperature may cause leaves to change color. VYZ
• Your group will now FORMALIZE these.
• if xxx is related to yyy, then
• (prediction when xxx increases, yyy happens)

Discuss the Hypotheses

• Chocolate may cause pimples. A B C D
• Salt in soil may affect plant growth. E G H J
• Bacterial growth may be affected by temperature.
  KLMN
• Stoplight cameras can save lives. PQRS
• Temperature may cause leaves to change color. VYZ

Make and Test Hypotheses

• And now, here we go!!!
• 0. the name of the game is
• Petals Around the Rose
• The name of the game is important.
• The answer is always 0 or an even integer.
• Once you figure the answer (get it right 4 times)
• do NOT tell anyone else, or
• you will turn into a turtle.
• 4. If anyone asks for details "The name of
  the..."

22
Hypothesis Testing
What's the independent variable?
("input") What's the dependent variable
("output") What is the relationship between
them? -- KEEPA YOU MOUF SHUT --- -- ltltonly
announce the prediction!gtgt -- When ready, say "WE
WANT TO BE TESTED" First FIVE groups to get 4
predictions right receive extra credit. If
wrong, no re-try.

Next Week's Challenge
I throw out a problem. Your group uses ANY
TECHNIQUES we have discussed, for 12 minutes.
record your results! I CHOOSE 3 groups to
present their solutions (3 mins
each.) ltltdrawing from my hat
re-entrant!!!gtgt The audience fills their ballots.
You will award the QUALITY OF IDEAS and the
BEST USE OF TECHNIQUES and the MOST
CREATIVE/Cool Presentations We plan to do this
THREE times in 75 minutes.

Tools for Challenge

• Techniques we've discussed so far
• verbal brainstorming
• written brainstorming
• sorting ideas, eliminating cliche's. Go for
  wierd and funny!
• the opposites game
• the acronym game Find suggestive phrases keyed
  to random letter strings
• requirements analysis the w questions
• restating the problem
• identifying sub-problems
• free writing
• One Word technique
• mind mapping and anything else you found in CC

How to prepare?

• Have a rehearsal!
• Do this at least twice (use about an hour )
• pick a problem (have everyone bring problems to
  meeting)
• decide which methods to apply (you can "split
  up" if needed)
• apply during a timed 12-minute interval,
  including report planning.
• practice presenting the results in 3 minutes,
  CLEARLY.
• If you do that twice, your group will be a
  smooth and efficient
• Ninja team ... (not..?). It may take more than
  this amount of time.
• BUT we'll do this two more times during the
  semester!

How to study for test?

• 1) Work hard on the Challenge activity.
• Exercise all the techniques until you understand
  them.
• 2) Review the material on Metaphor and Humor
• 3) Look through these Powerpoints, scavenging
  anything that
• is interesting.
• 4) Get a good night's sleep.
• 25 multiple choice questions. You can do it!
