Science
|
A process that uses logic, critical thinking, and observations to solve problems. (Does not have to be lab experiment.)
|
|
|
Scientific Method
|
A process of doing Science.
|
|
|
Observation
|
Something you notice about you surroundings using any of your senses.
|
|
|
Purpose
|
A question you ask about the observations you made.
|
|
|
Hypothesis
|
A possible answer to a scientific question based on logic, observation, prior knowledge, and evidence that is testable.
|
|
|
Experiment
|
The testing of a hypothesis by collecting and researching data. A data table is often used.
|
|
|
Analysis & Conclusion
|
Evaluating and interpreting your data to determine whether or not your hypothesis is correct. A graph is often used in order to analyze the data.
|
|
|
Repeat
|
If your data does not support you data to hypothesis, create a new one and try again. Even if the data supports you hypothesis, do everything again in order to be sure you get the same results each time.
|
|
|
Theory
|
Something used to explain a wide set of observations and facts that is supported by a lot of evidence and has been tested multiple times by multiple people.
|
|
|
Quantitative Observations
|
Observations that are made using measurements and a numerical opint of view.
|
|
|
Qualitative Observations
|
Process in which your senses are used to make observations.
|
|
|
Direct Observations
|
When you use only your sight to make observations about something.
|
|
|
Indirect Observations
|
Observations made using senses other than you sight.
|
|
|
Inferences
|
Something you believe to be true based only upon observation and prior knowledge.
|
|
|
Variables
|
Things that could change during an experiment. There is always at least two variables in an experiment.
|
|
|
Independent Variable
|
The variable that you control and change in an experiment.
|
|
|
Dependent Variable
|
This is the variable that you have no control and changes as a result of the independent variable(s).
|
|
|
Controlled Experiment
|
An experiment done to test the effects of one single independent variable at a time while the researcher tries to keep all the other independent variables constant.
|
|
|
Control Group
|
When the independent variable is not changed in order to provide a comparison and conditions are set to normal.
|
|
|
Experimental Group
|
When the independent variable is changed. It is ten compared to the control group.
|
|
|
The Metric System
|
The universal system of measurements used by scientists all over the world. It is based on the number ten.
|
|
|
Meter
|
A basic unit of length.
|
|
|
Liter
|
A basic unit of volume.
