Bell Work: 8/25/15
Students want to determine which type of plant will best survive in a hot, dry environment. They place four different types of plants in identical pots, and put all of the plants by the same large window. They give each plant the same amount of water every day.
Which of these is the independent variable for the students’ experiment?
A) amount of waterB) health of plantC) type of plantD) amount of sunlight
You must write the question, answer, and JUSTIFY!

Standards and Essential Questions:
SPI 0807.Inq1 (Variables and Controls)Design a simple experimental procedure with an
identified control and appropriate variables. SPI0807.Inq.3
Interpret and translate data into a table, graph, or diagram.
Essential Questions: Can I use procedures to identify controls and
variables? Can I translate data into tables, graphs, or diagrams?

Independent Variables
In an experiment……you should only test for ONE key thing at a time
When you repeat the experiment……only change this ONE key thing
This ONE thing is called…
AN Independent VariableAlso known as the manipulated variable

SPI 0807.Inq1(Variables and Controls)
What is an independent variable?The one thing YOU change each time you duplicate an experiment
Here is our simple memory trick to help you with this.
Independent variable begins with the letter “I” So, remember the letter “I” Imagine yourself doing the experiment and ask yourself
“What ONE thing will I change when repeating the experiment?”
That one thing will be
The Independent VariableAlso known as the manipulated variable

Dependent VariablesWhat is a dependent variable?Other factors that change because of the independent variable. These are the things that YOU DO NOT CHANGE…they change on their own while you are making observations. In other words, “anything that changes on its own” while the experimenter is observing it will be a ….
