Use Scientific Thinking Tkill of Problem Solving

Use your scientific thinking skills
instead of jumping to the obvious conclusion.
1. Identify the problem. Kids are sick and
you want to find out what caused the
problem.
2. Collect information/investigate. So
you found out that the hot-dog eaters got sick
and the brown baggers didn’t. Keep going.
Ask questions that will take you scientifically
to a conclusion before you leap to one. Did
some students who ate hot dogs not end
up vomiting? Did they all have mustard or
ketchup or relish? Did something else come
with the hot dogs, like chips or pickles?
Were all the sickies from the same lunch
period?
Expand your research to the kitchen. Did
the same cafeteria server handle hamburgers
and hot dogs? Did only one server handle
the dogs? Did anybody in the kitchen get
sick? Are there any toxic substances near
the hot-dog-preparation area? Check out the
hot-dog oven. What about pans and serving
platters? Did anybody examine those hot
dog buns? Are there uncooked hot dogs lying
around? Never shortcut the informationgathering
step in a scientific investigation.
3. Form your hypothesis. Maybe, after all
your investigations, you still blame the hot
dogs. In your opinion, the hot dogs are

responsible for student sickness that
afternoon. That’s your theory, your
hypothesis.
4. Draw your conclusions. You can’t do that
until you test your hypothesis, right? If
you’re brave, you might run your own
experiment and eat one of the suspect hot
dogs. Or you can ask your science teacher to
run a substance analysis on a hot dog. The
fourth step is the time to test your theory
and confirm your hypothesis or adjust your
conclusion.
You decide that you’re not brave, so you
don’t eat the hot dog. Your teacher examines
the food, but it comes up clean. It’s time to
consider a new hypothesis. Since only one
person prepared the hot dogs, and he didn’t
touch the hamburgers, you shift your
suspicions to him. To test your new theory,
you spy on him. Sure enough, you see him
cough without covering his mouth. The
man confesses that he just got over the flu.
Case solved.
