Question

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

Answer 1

1. Scientific question: Can detergent affect flower growth?

2. IV: The soap used in the study

3. DV: Flower growth

Explanation:

A scientific question is a well-sustained question about a given phenomenon of the real world which can be answered by experimental and/or observational procedures. A good scientific question must be testable and lead to falsifiable hypotheses. The dependent variable is the variable that is being measured in the experiment, (i.e. it is being affected by the experimental procedure). On the other hand, the independent variable is the variable that isn't changed by the other variables that are being measured in the experiment.
