Science
|
A process that uses logic, observations and prior knowledge to solve problems
|
|
|
Scientific Method
|
A process of doing Science
|
|
|
Observations
|
Something you notice about your surroundings using any senses
|
|
|
Purpose
|
A question you ask about observations you made
|
|
|
Hypothesis
|
A possible answer to the question that must be testable based on logic, observations, and prior knowledge; explains hypothesis
|
|
|
Experiment
|
Testing of you hypothesis by using data
|
|
|
Analysis & Conclusion
|
Evaluating data to see if hypothesis is correct, often using graphs
|
|
|
Repeat
|
Repeat your experiment even if data supports hypothesis to make sure you get the same answer each time
|
|
|
Theory
|
Used to explain observations and facts with large amounts of evidence; tested mult. times by mult. people
|
|
|
Quantitative Observations
|
Involve taking measurements, such as temp, mass, size, distance, velocity, ect. Any numerical observation
|
|
|
Qualitative Observations
|
Involve describing properties that may be used to identify it, such as color, smell, fell, texture, etc.
|
|
|
Direct Observations
|
Things you observe by seeing/watching
|
|
|
Indirect Observations
|
Things detected with your senses
|
|
|
Inference
|

|
|
|
Variable
|
Conditions you change during experiments
|
|
|
Dependent Variable
|
Variable that changes as result of independent variable, variable you don't have control
|
|
|
Controlled Experiment
|
An experiment that tests effects of one independent variable at a time
|
|
|
Control Group
|
Independent variable isn't changed to provide a comparison, conditions set to "normal"
|
|
|
Experimental Group
|
Independent variable is changed & results compared to control group
|
|
|
Metric System
|
The universal measurement used by scientists. Used all over the world, based off the number 10
|
|
|
Meter
|
Length, usually measured by metric stick or metric ruler
|
|
|
Liter
|
Volume, measured by graduated cylinder or beaker
|
|
|
Gram
|
Mass, usually measured by a scale or balance
|
|
|
Independent Variable
|
Variable you change, you have direct control
