Part II: Applying Science
to Everyday Life
Recently, Earl attended a
picnic at his daughter’s school. The picnic was a potluck, and the food was
served outdoors. Contributions included hamburgers, hot dogs, baked beans,
potato chips, potato salad, coleslaw, apple pie, and vanilla ice cream. Within 24
hours of the picnic, several attendees developed symptoms of food poisoning. Of
the 50 people who attended the picnic, only 30 people became ill. Every person
at the picnic ate something, but not every person had an opportunity to sample
each item. Earl noticed that the potato salad he started to eat was warm. He
also noticed that his hamburger was somewhat pink in the middle and not fully
cooked. Earl wonders if eating the hamburgers or the potato salad could be
responsible for making some attendees ill. Earl has begun to apply the
scientific method to this common problem. Complete each of the following tasks
in 200 to 300 words.
1. How would the scientific method help Earl
create an experiment to determine which food sources made people sick?
2. Describe the steps of the scientific method
3. Describe the remaining steps Earl will use if
he decides to use the scientific method to determine what made the people sick.
