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.
