What is the first step for any scientific investigation?

Observation

What is the difference between a hypothesis and a theory?

Hypothesis: a proposed explanation Theory: an organized collection of data, observations, hypothesis and information

Measurements made during an experiment are called…

Data

What is a controlled experiment?

Experiment where only ONE variable is changed

Explain the difference between a control group and an experimental group

Experimental group: everything is the same as the control group EXCEPT for one variable

What is an independent variable?

The variable deliberately changed by the researcher

The variable that changes in response to the independent variable.

What is… the dependent variable?

Give the independent variable for the following: Children who drink two glasses of soda a day will be on average two inches shorter than those who do not drink soda.
