                                                           The Scientific Method
      Did you ever wonder why the water level in a glass doesn't change when the ice in the glass melts (融化)?
To find out why, you can use the scientific method. Used by scientists in various situations, the scientific
method is also a clear and logical way to solve many real-world problems, as the procedure below indicates.
Steps in the Scientific
Method		Examples
State the problem or
question.		"Why doesn't the water level in a glass rise when ice melts?"
Collect information about the problem,
using your own
observations and
research. 		You already know that ice is frozen water. From your research,
you learn that water and ice are made of water molecules (分子).
Form a hypothesis,
or a best
guess based on the
information. 		"The molecules in water appear to be closer together than they are
in ice."
Test the hypothesis by doing an experiment.Fill four glasses with ice. Then pour water over the ice and fill
each glass to the rim. As the ice melts, you observe that the water
does not spill over the top of the glasses. Each time you repeat the experiment, you get the same results.
Draw a conclusion
based on your
results. 		Molecules are closer together in water than they are in ice.
1. Which of the following is another good title for this passage?
A. Research and Conclusion
B. Observation and Experiment
C. Follow the Steps to Find Out Why
D. Mix Water with Ice and Get the Result
2. A hypothesis is _______.
A. a guess about the cause of something
B. the first step in the scientific method
C. a conclusion about water molecules
D. an experiment on ice and water
3. This passage suggests that _______.
A. repeated experiments lead to the right result
B. research should be done in various situations
C. your hypothesis can prove your experiment results
D. a logical method is needed when solving problems
4. The chart in the passage is useful because it _______.
A. shows a diagram of how ice melts
B. shows steps and examples
C. compares water with ice
D. explains cause and effect
