|
|
Define:
Theory |
A hypothesis that has been tested with a signifacant amount of data

|
|
When someone tells you that "science has proven", what should you say?
|
Science hasn't proven anything.
|

No, it does not.

|
To destroy a scientific law, you need only one counter-example.

|
|
What was the observation that Halley made to form a hypothesis?
|
The observation was that the objects similar to the one he was studying had been seen before by other scientists at regular intervals in history.
|
|
|
What was the hypothesis?
|
The hypothesis was that the object he was studying was the same thing that the other scientists had seen before.
|
|
|
What was the experiment that confirmed the hypothesis?
|
The experiment was to confirm the presence of the comet again in 1758.
|
|
|
Regular appearances of Halley's comet have been found in history as far back as 2,000 years ago. Is the existence of Halley's comet a theory or a scientific law?
|
The exsisence of Halley's comet is now a scientific law.
|
|
|
Put the following steps of the scientific method into their proper order:
A)Form a hypothesis B)Theory is now a law C)Make observations D)Hypothesis is now a theory E)Perform experiments to confirm the hypothesis F)Perform many experimentsover several years |
C)Make observations
A)Form a hypothesis E)Perform experiments to confirm the hypothesis D)Hypothesis is now a theory F)Perform many experiments over several years B)Theory is now a law |
|
|
If a hypothesis does not agree with the experiment which was designed to confirm it, what two choices do you have?
|
You can either discard the hypothesis or modify it to become consistent with the experiment.
|
|
|
If a theory does not agree with the experinment that was designed to to test it, what two chioces do you have?
|
You can either discard the theory or modify it to become consistent with the observations.
|
|
|
In the text, I told oyu about Lowell's belief that there were canals on Mars. Name the observations which led to his hypothesis and experiments that were used to confirm the hypothesis.
|
The observation that led to Lowell's hypothesis was the fact that there were faint lines on the surface of Mars. The experiments used to confirm the hypothesis were Lowell's detailed studies of Mars' surface.
|
|
|
Why was the discovery of high-temperature superconductors so startling to scientists?
|
A generally-accepted scientific law said that it was impossible to have high-temperature superconductors.
|
|
|
What are the three limitations of science?
|
A)It cannot prove anything
B)It is not 100% reliable C)I must conform to the scientific method. |
|
|
Can science be used to study events that will never, ever happen?
|
Yes, it can.
|
|
|
Can science be used to study religious ideas?
|
Yes, it can.
|
|
|
What were the observations I used in the last section of the module to form a hypothesis about the Bible?
|
Many people draw strength, hope, and encouragement from the Bible.
|
|
|
What was my hypothesis?
|
I hypothesized that the Bible is the Word of God.
|
|
|
What were the experiments I designed to confirm the hypothesis?
|
I searched the Bible for knowledge of future events.
|
|
|
Did I prove my hypothesis?
|
Of course not! Science cannot prove anything.
