BIG Idea: What?
· The independent variable is what the
scientist changes on
purpose. They are in control of some aspect of that variable.
· The dependent variable depends the
independent variable – the scientist does not control it, s/he just measures/observes it.
How do I identify
them?
1)
Underline
nouns -
those are usually your variables.
2)
Look for
what the scientist changes - that’s the independent variable.
3)
Look for
what the scientist measures - that’s
PROBABLY your dependent variable.
CHECK YO’ SELF!
“Is the dependent variable affected by
what the scientist changes?”
THERE’S A PART 2?
How do I come up
with a dependent variable?
1)
Decide
what the scientist is changing (independent variable)
3)
Make
sure that it’s something the scientist can measure.

variable for the scientist.
1) Hayley is doing
an experiment to find the healthiest soda brand.
Independent Variable:
_____________________________________
What could be her dependent variable?
