Textbook Question
Chapter 1, Problem 9ALQ
If all scientists use the scientific method to try to arrive at a better understanding of the world, why do so many debates arise among scientists?
Expert Solution & Answer

Students have asked these similar questions
What are several political, social, or personal considerations that might affect a scientist's evaluation of a theory?What are examples of how such external forces have influenced scientists in the past?What are methods by which such bias might be excluded from future scientific investigations?
Describe the scientific method, and indicate by example how it is used to answer questions about situations we encounter in our every day lives.
In the course of a conversation, you observe that three of your friends like horror movies. Horror movies happen to be your favorite type of movie as well. You also know
that all of these friends were born in the same week that you were, even in the same year.
An astrology-loving friend hypothesizes that people born in that week like horror movies more than other genres of movies. You decide to use the scientific method to test
this hypothesis.
Part A
What should you do next?
O Come up with a theory to explain why movie preference is related to birth week.
O Perform experiments to test your hypothesis.
O Propose several alternative hypotheses.
O Refine your hypothesis.

However, making observations, formulating hypotheses, and performing experiments are generally components of “doing science.” Read the following passage, and list any observations, hypotheses, and experiments.

They both notice that (lie raisin falls to the bottom of the glass. Soon, the raisin rises Lo the surface of the ginger ale, then sinks. Within a couple of minutes, it rises and sinks again. Joyce asks. “I won der why that happened?” Frank says. I don’t know, hut let’s see if it works in water.” Joyce fills a glass with water and drops the raisin into the glass. After a few minutes, Frank says, “No, it doesn’t go up and down in the water.” Joyce closely observes the raisins in the two glasses and states, “Look, there are hubbies on the raisins in the ginger ale but not on the raisins in the water.” Frank says, ‘it must be the bubbles that make the raisin rise.” Joyce asks, “OK, hut then why do they sink again?”arrow_forward
