What is Living Environment? a. _____________________________________________________ _____________________________________________________ III. The Methods of Science? a. You arrive home late at night, walk up to your house door, unlock the door, and reach in to the light switch just inside the front door. The light does not come on! Now what? b. As a normal human being, you will go through a mental and physical process of hypothesis testing. The steps happen very rapidly in your mind and, prior to this, you may not have had names for the various steps. Nevertheless, I hope you will recognize what your brain is doing as you stand there in the darkness. You are already a scientist, as you will see, you just didn't know it! c. The technique used by scientists to solve problems is known as the ______________________________

The problem is a ________________________________ _______________________________________________ b. Propose a Hypothesis i. A hypothesis is _______________________________________ ________________________________________________ c. Test the Hypothesis i. The scientist must design _______________________________ ________________________________________________ _____ ii. The experiment, called a _________________________, should test only one __________________. iii. The factor to be tested is called _______________________. iv. Another experiment that is the same in every way but does not contain the variable is called the _______________________. d. Make Observations i. From the experiment, the scientist makes observations ________________________________________________ ___

From these observations, a __________________________ ________________________________________________ e. State a Conclusion i. The answer to the problem is called the conclusion. ii. To be valid or true, _______________________________ _____________________this is called __________________ iii. These facts result from observation and experimentation. f. Repeat the Experiment i. The experiment is repeated many times to check the conclusions. ii. When, after repeated testing, many scientists reach the same conclusion, the conclusion may be called a scientific law.
