Science
|
Science is a process of using logic and prior knowledge to solve problems. Also, does not need to be a lab experiment.
|
|
|
Scientific Method
|
The process of doing science.
|
|
|
Observation
|
Something you detect in your enviroment with any of your senses.
|
|
|
Purpose
|
A question used to figures out something about your observation.
|
|
|
Hypothesis
|
A possible logical explanation to your question that is testable.
|
|
|
Experiment
|
Testing your hypothesis by testing and recording data, possibly in a data table.
|
|
|
Analysis and Conclusion
|
Evaluating and interpreting your data to decide whether or not your hypotheses was correct, graphs are often used.
|
|
|
Repeat
|
Repeating your experiment whether your hypothesis was correct or not. If your hypothesis is incorrect then when repeating you create a new hypothesis.
|
|
|
Theory
|
Used to explain a great amount of facts and observations which have been tested multiple times and have a good amount of evidence.
|
|
|
Quantitative Observations
|
Observation that involve taking measurements such as temperature, mass, size, or anything that has to do with numbers.
|
|
|
Qualitative Observations
|
Observations that describe the general appearance and properties such as color, feel, smell and texture.
|
|
|
Direct Observations
|
Observations that you make using sight.
|
|
|
Indirect Observations
|
Observations you make with any other sense besides sight.
|
|
|
Inferences
|
Something you assume to be true based on prior knowledge and/or observations.
|
|
|
Variables
|
At least two conditions in every experiment that can change during the the experiment.
|
|
|
Independent Variable
|
The variable that the researcher has direct control of.
|
|
|
Dependent Variable
|
The variable the researcher does not have control; changes because of the indirect variable.
|
|
|
Controlled Experiment
|
Experiment where everything is kept constant so that you can test the results one independent variable at a time.
|
|
|
Control Group
|
Variable is not changed during experiment, everything is set to normal. Used to that yo can test the results of one independent variable at a time.
|
|
|
Experimental Group
|
Independent Variable is changed, results are compared to control group results.
|
|
|
Metric System
|
System of measurement used all over the world by scientists based on the number 10.
|
|
|
Meter
|
Metric unit measuring length.
|
|
|
Liter
|
Metric unit measuring volume.
|
|
|
Gram
|
Metric unit measuring weight.
