6. Dependent vs. Independent Variables
Scientist use an experiment to search for cause
and effect relationships in nature. In other
words, they design an experiment so that
changes to one item cause something else to
change in a predictable way.
These changing qualities are called variables. A
variable is any factor, trait or condition that can
exist in differing amounts or types. An
experiment usually has three kinds of variables:
independent, dependent and controlled.
The scientist focuses their observations on the
dependent variables to see how it responds to
the change made to the independent variable.
The change of the dependent variable is caused

7. Dependent vs. Independent Variables
Experiments also have controlled variables.
Controlled variables are factors that a scientist
want to remain constant (the same), and they
must observe them as carefully as the
dependent variables. Controlled variable are
used to compare the dependent variable’s
changes in experiment’s relationship and keep
the tests fair.
Underline the independent
variable and
circle the dependent variable in
each.

8. Dependent vs. Independent Variables
1.The price of gas determines
how much I will purchase.
2. If I do not want to gain
weight, the amount of
exercise I need to do is a
result of how much I eat.

9. Hypothesis
Based on what you know about the
experiment…..
In your Cornell Notes:
If we test four different types
of corn under similar
conditions and change only
the infestation level, then we
should be able to determine
and give evidence for which
corn type will provide the
highest yield and withstand

• There are 8 different data collection tests.
• Continue until all Data is Collected.

11. TODAY’S TASK LIST
1) Work with a partner from your table OR
individually.
2) Pick up your Assigned Computer.
3)You will be held responsible for its well-
being.
4) Ask Clarifying Questions as needed.
5)Begin experiments & collection of data
6) Our Goal is complete 8 tests by the end
of Friday’s class.

12. HOMEWORK
1)We will be working in class on the
Virtual Lab tomorrow and next week.
2)You will have homework over the
weekend if you do not finish
collecting data on 8 experiments.
3)This lab is not due until Wednesday
of next week.
