Science Fair Projects

An experiment is performed on plants to see how different liquids affect plant growth. Each plant in the experiment is given a different liquid; water, apple juice, or milk. Each plant has the same amount of soil, sunlight, and listens to the same music. In this investigation, what is the dependent variable?

• Type of plant

• Water, apple juice, milk

• Plant growth

• Color of the plant's leaves

In a scientific experiment, the outcome or response that is measured is known as the:

• Independent variable

• Dependent variable

• Controlled variable

• Confounding variable

The Purpose of a Science Project is

• The testable question for the project

• The "why" you decided to do the project

• How you are doing the project

• Research the project

The purpose of a control group in an experiment is to:

• Confirm the results

• Provide a standard of comparison

• Manipulate the independent variable

• Measure the dependent variable

A science fair project should be based on a(n) ______.

• demonstration

• experiment

What is a control group?

• The students who wait till the last minute to do their experiment

• They tell everyone what to do

• You have to give exact instructions

• A group that does not receive 'treatment' in an experiment (you can only have this with people experiments!)

Confounding variables are things that may happen that make your experiment unreliable. If we are molding strawberries in three locations, which of the following could be a confounding variable?

• Using all the same type of fruit

• Little brother touching the experiment when he comes home from baseball practice

• The same sized strawberries

• How much mold grows
