Gail and Howard liked to travel. Every holiday they went to a different place.They were always careful when they left the house. They locked the doors and windows. Then Gail took the extra keys and left them with her mother.
Gail and Howard spent two weeks camping in the mountains. They had a great time, but when they came home, all they wanted to do was to sleep. They both looked for the keys everywhere, but no luck. The keys were not anywhere. They went to their mother’s house, but she wasn’t home.
Howard had to climb up to open a window, but he forgot that the window was locked, too. He climbed back down, broke the window with a stick and climbed into the house. He went to open the front door for Gail, only to find the police.
A frightened neighbor heard the noise and thought there was a robbery; so she called the police. Howard was almost caught by the police but luckily their neighbors proved that he lived in that house. Finally, Gail and Howard brought their luggage in, climbed into bed, and fell asleep right away.

What makes a person a scientist? Does he have ways or tools of learning that are different from those of others? The answer is “no”. It is not the tools a scientist uses but how he uses these tools that makes him a scientist. You will probably agree that knowing how to use a power is important to a carpenter. You will probably agree, too, that knowing how to investigate, how to discover information, is important to everyone. The scientist, however, goes one step further, he must be sure that he has a reasonable answer to his questions and that his answer can be confirmed by other persons. He also works to fit the answers he gets to many questions into a large set of ideas about how the world works.
The scientist’s knowledge must be exact. There is no room for half right or right just half the time. He must be as nearly right as the conditions permit. What works under one set of conditions at one time must work under the same conditions. If the conditions are different, any changes the scientist observes in a demonstration must be explained by the changes in the conditions. This is one reason that investigations are important in science. Albert Einstein, who developed the Theory of Relativity, arrived at this theory through mathematics. The accuracy of his mathematics was later tested through investigations, and Einstein’s ideas were shown to be correct. A scientist uses many tools for measurements. Then the measurements are used to make mathematical calculations that may test his investigations.
