• Factors that are kept the same

• Information collected from the experiment

What are constants?

• The factor that is measured in an experiment

• A testable answer to a scientific question

• A variable that is changed in the experiment

• Factors that are kept the same

• Information collected from the experiment

What is the control group?

• The factor that is measured in an experiment

• A testable answer to a scientific question

• A variable that is changed in the experiment

• The group the independent variable is compared against

• Information collected from the experiment

What is the test group?

• The factor that is measured in an experiment

• A group that experiences the independent variable

• A variable that is changed in the experiment

• The group the independent variable is compared against

• Information collected from the experiment

An experimenter conducted an experiment to determine what amount of baking powder makes a type of cake rise the highest. The experimenter tested the cake with no baking powder, 1/2 teaspoon, 1 teaspoon, and 2 teaspoons of baking powder. They used the same pan, stove, mixer, ingredients, recipe, and instructions. The experimenter then measured how tall the cakes were in inches after baking.

• Amount of baking powder

• Dependent Variable(s)

• Pan, Stove, Mixer, Ingredients

• Controlled Variables/ Constants

• No baking powder

• Control group

• How tall the cake is (inches)

• Independent Variables

What is wrong with this experiment:

An experimenter conducted an experiment to determine if putting fertilizer on their indoor plants make them bloom. The experimenter put plant A, an African Violet, on a window sill and was not given fertilizer for 6 months. Plant B, a philodendron, was placed on the kitchen table and was given fertilizer for 6 months. Both plants had the same pots and water amounts. The experimenter recorded how many flowers bloomed during that time. Using the data, the experimenter concluded that the African Violets had more flowers, so fertilizer does not make indoor plants bloom.

(Select all correct answers)

• Different amounts of fertilizer

• Different locations

• Different numbers of flowers

• Different Types of flowers
