List the 5 steps of the scientific method
(1) observation, (2) hypothesis, (3) test hypothesis, (4) state and interpret results, (5) form new hypothesis
These are the factors that remain identical in an experiment
Control
In an experiment testing food preference, you feed your dog the same time each day, using the same dishes and change the food. Which is the variable in this experiment?

What is the second step in the scientific method
Form a hypothesis
A scientist wants to see if the brightness of light has any effect on a moth being attracted to the light. The brightness of the light is controlled by the scientist. This would be the _________variable. How the moth reacts to the different light levels (distance to light source) would be the _________variable.
Independent, dependent
What is the third step of the scientific method
Test the hypothesis
This is the factor that changes in the experiment
Variable
What is the fourth step in the scientific method
analyze results
_________ is the variable being tested and measured in a scientific experiment.
dependent
What is the fifth step in the scientific method
form a new hypothesis.
________ is the variable that is changed or controlled in a scientific experiment
independent
If the _________variable is changed, then an effect is seen in the _________ variable.
independent, dependent
What is the first step of the scientific method?
observation
What are the two things a hypothesis must be
