Scenario: A horticulturist (plant scientist) complains to the city that a nearby residence is ruining his flowers
because of the detergent being used to wash their cars. The soap ruins into a stream that goes near his flower beds.
As an inquiring scientist, you want to find out whether soap can affect flower growth.
1. (pts) What is the scientific question that is being asked by the horticulturist (plant scientist) in the background
Information?
2. (6pts) Therefore what is the Independent Variable (IV) that you're going to test?
3. (6pts) The Dependent Variable (DV) is what is affected by the Independent Variable. What is the Dependent Variable
In this experiment?
4. (12pts) Based on the scientific question (or problem), develop a hypothesis (prediction) that you are going to test by
performing the experiment.
IV
then
DV
11
because
• Perform the experiment by setting up your Control group and Experimental group. You have a choice in selecting items
but remember all factors must be kept the same in each group except for the one thing you are testing. You are

6. (10 pts) A) Why did your Control Group NOT have detergent added to it? B) Explain the purpose of a Control Group in
an experiment
7. (10 pts) After performing the experiment, measure the height of each plant using the ruler provided. You can move it.
Place the bottom of the ruler at the base of the plant and measure its height. Record the data you collected and
the factors included in each group below.
