What are the kinds of Science?
|
Pure Science, and Applied Science
|
|
|
-Science carried out to answer a question or gain knowledge
-Examples: biology, chemistry, physics, and geology |
PURE SCIENCE
|
|
|
-Science that takes the knowledge learned in pure science and uses it to solve real world problems.
-Examples: Environmental Science and medicine (doctor) |
APPLIED SCIENCE
|
|
|
Common steps that biologists and other scientists use to gather information and answer questions
|
SCIENTIFIC METHOD
|
|
|
What are the steps in the scientific method?
|
1.)Observing
2.)Problem 3.)Hypothesis 4.)Experiment-Analyze data 5.)Conclusion |
|
|
-A close look at a situation (including its causes and effects.)
-Must use all senses, not only sight. |
Observing
|
|
|
-Coming up with an explanation for the observations that is testable
-A hypothesis is not a random guess, but an educated one. It is what the scientist expects to happen. |
Hypothesizing
|
|
|
-Perform a procedure that tests a hypothesis under controlled conditions
-Controlled Experiment -An experiment with two groups: the control group and the experimental group |
Experimenting
|
|
|
the group in which all the conditions are kept the same
|
Control Group
|
|
|
The test group in which all the conditions are kept the same, except for the single condition that is being tested.
|
Experimental Group
|
|
|
The conditions that can affect an experiment
|
Variables
|
|
|
The condition in the experiment that is changed, it affects the experiment outcome.
|
Independent Variable
|
|
|
A second condition that is not changed, but the scientist observes and measures this condition to see if it has changed after changing the independent variable.
|
Dependent Variable
|
|
|
-Information obtained from experiments
-Can be numerical (distance) or verbal (activites) |
Data
|
|
|
-Making statements about the hypothesis based upon the experimentation
-Defines whether the hypothesis is true or not |
Conclusion
|
|
|
-Report the results in scietific journals
-Other scientist can now try to verify the results by repeating the experiment |
After the Conclusion
|
|
|
What is one kind of research?
|
Descriptive Research
|
|
|
-Research that results in observational data such as written descriptions
-Example:How a particular wild animal reacts to events in its environment |
