1) What is a scientific discovery (whether discussed in this course or not) that would not have
been possible without one of the important scientific discoveries discussed in this course?
2) What is one way that the study of physics can help explain phenomena in a seemingly
unrelated field, like biology?
3) Aside from becoming a physicist, what is one career path that could be helped by a strong
understanding of physics?
4) What is an example of a scientific topic that requires knowledge of at least two different
branches of physics?
5) How has an advancement in physics impacted your day‐to‐day life?
6) How would you differentiate between a theory and a hypothesis, when reading a scientific
text?
7) When you are reading the results of scientific experiments, what are some features that you
would expect to see in the design of a high‐quality experiment?
8) What is one way that complete and accurate laboratory reports help prevent bias and fraud
from influencing scientific findings?
9) How does improving measurement accuracy help provide more valid scientific results? How
does improving measurement precision help provide more valid scientific results?

10) Gerard is measuring the speed of a remote‐controlled airplane. He measures that the
airplane travels 110 m in 5.4 seconds, giving a speed of 20 m/s. What will Gerard need to
change, if he wants to get a more precise value for speed?
