Scientific Method 
Steps scientists use to answer questions and solve problems.

Ask question/ state problem, make observations, form hypothesis, test hypothesis, collect and analyze data, draw conclusions, and repeat/ communicate 
Name all the steps in order for the scientific method.

Science 
Understanding the world around you/ systematized knowledge derived from observation, study, and experimentation.

Observation 
Use of senses to gather information.

Hypothesis 
Testable explanation or answer to a question/ educated guess.

Prediction 
Logical statement about what will happen if hypothesis is correct.

Controlled experiment 
Experiment that tests only ONE variable at a time.

Variable 
Factor being tested/ difference found between control and experiment groups.

Method of testing predictions by examining associations between two or more events. 
What is the correlation method in experimenting?

Control Group 
Set up in an experiment that does NOT contain the variable.

curiousity, skeptical, openness, intelectual, honesty, imagination, creativity 
What are three traits scientists should have?

Experimental group 
Set up in an experiment that contains the variable.

Statistics 
Branch of math that collects and classifies data in the form of numbers.

Data 
Information that is gathered during an experiment often in numeric form.

Average/mean 
Number obtained by adding together all data for one characteristic and dividing by number of individuals.

Distribution 
Relative arrangement of members of statistical population/ least to most "things."

Model 
Representation of an object on system too small/ large to be observed normally.

Probability 
Chance that something will happen (odds).

physical, graphical, conceptual, mathematical
