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
