2
Q
- What does it take to destroy a scientific law?
A
Only one counter example
3
Q
- (Read story on page 57, first.) After searching other scientists’ works, Halley noted that similar objects that followed a similar path were observed in 1531 and 1607. What part of the scientific method does this represent?
A
Observation
4
Q
- (Read story on page 57, first.) Halley decided that those objects were, in fact, the same thing he was studying, and that is passed by the earth roughly every 76 years. What part of the scientific method does this represent?
A
hypothesis
5
Q
- (Read story on page 57, first.) Halley predicted that the object would be seen again in 1758. On Christmas in 1758, the object was indeed seen again. What part of the scientific method does this represent?
A
Experiment and data collection
6
Q
- (Read story on page 57, first.) It is now called Halley’s comet, and it comes into view of the earth every 76 years. Is the existence of Halley’s comet a theory or a scientific law or a theory?
A
Scientific law
7
Q
- Put the following steps of the scientific method into their proper order:
- a. Form a hypothesis
- b. After generations of data confirm the theory, it becomes a scientific law
- c. Make observations
- d. Analyze data to see if confirm hypothesis or doesn’t confirm hypothesis
- e. Perform experiments to collect more data
- f. After significant amount of data has been collected, the hypothesis becomes a theory
