Physical Sci Chapter 1 Sci Method, Graphing

In order to be accepted, a scientific theory must be

•  widely tested and supported by extensive data
•  based on the results of a single experiment
•  controversial and cause debate
•  in line with all previous historical ideas

In an appropriately designed experiment, a scientist is able to test the effect of

•  a single variable
•  multiple variables
•  the hypothesis
•  scientific observations

A series of steps used by scientists to solve a problem or answer a question. 

• scientific method
• recipe
• data collection
• metric system

Which is NOT a step in the scientific method?

• Make observation
• Form a theory
• Collect data
• Form a hypothesis

What is the first step in the scientific method?

• Data

• Conclusion

• No Horse Play

• Observe a problem

A possible explanation to a problem that has not yet been tested. 

• data
• theory
• hypothesis
• fact

True or False: Your hypothesis can never be wrong.

• True
• False

This variable in an experiment is the one being changed by the scientist, or tested.

• dependent variable
• independent variable
• data
• control group

Dependent variable means

• the scientist controls what to test
• educated guess
• ask a question
• what is being measured to answer hyothesis

In a controlled experiment, how many variables can be worked with at a time? 

• one
• none
• two or more
• how ever many makes sense.
