INTRODUCTION TO SCIENCE
Definition of Science
noun
the intellectual and practical activity encompassing the systematic study of the structure and behavior of the physical and natural worldthrough observation and experiment : the world of science and technology.• a particular area of this : veterinary science | the agricultural sciences.• a systematically organized body of knowledge on a particularsubject : the science of criminology.• archaic knowledge of any kind.
VARIABLES
Variables - the factors that effect the outcome of the experiment.
Independent variable - the variable we deliberately change to see what effect it has on the results.
Dependent variable - the variable that is measured to see the effect the changes in the independent variable. (Results)
Controlled variables - the other factors that need to be kept constant so that they do not effect the results. Measuring devices are never controlled variables.
HYPOTHESIS
Hypothesis - prediction of the outcome on an experiment.
A hypothesis should always state the relationship between the independent variable and dependent variable.
Never include the explanation of the hypothesis in the hypothesis itself.
BUNSEN BURNERS
Steps for lighting a bunsen burner:
1. Rotate the collar to close the air hole.
2. Light the match.
3. Turn the gas on.
4. Light the burner from the side.
The yellow flame is used as a safety flame between heating. It's cooler and more easily seen. To create a hotter flame, rotate the collar to open the air hole, this is called a blue flame. The hottest part of this flame is above the blue cone. Decreasing the gas flow creates a smaller flame. Use a blue flame to light something.
