What is the purpose of a controlled experiment?

• To change multiple variables at once

• To isolate the results to one variable

• To test the hypothesis without any controls

• To ensure all variables are dependent

Why are controlled experiments essential?

• They allow for multiple variables to be tested simultaneously

• They produce unreliable results

• They ensure results are due to the independent variable

• They do not require any controls

In the example of testing how fertilizer affects plant growth, what is the experimental group?

• The group without fertilizer

• The group with fertilizer

• The group with different types of plants

• The group with different amounts of water

What must be kept the same in a plant growth experiment to ensure it is fair?

• Type of plant, amount of water, type of soil, and temperature

• Type of plant, amount of sunlight, type of fertilizer, and temperature

• Type of plant, amount of water, type of fertilizer, and temperature

• Type of plant, amount of sunlight, type of soil, and temperature
