Note from the author:

Independent Variables, Dependent Variables, Constants Practice

Independent Variable: The condition in the experiment that is changed on purpose
Dependent Variable: The condition in the experiment that results from that change
Constants: Conditions in experiments that are held constant (do not change)

A change in a dependent variable DEPENDS on change in an independent variable. For example, the amount of chairs in my classroom is DEPENDENT on the number of students in my class (independent). Having more students causes me to add more chairs. Having more chairs would not cause me to add more students.

Does heating a cup of water allow it to dissolve more sugar? Temperature of the water is measured in degrees Centigrade. Amount of sugar is measured in grams.

Does fertilizer make a plant grow bigger? Amount of fertilizer measured in grams, quantities of water measured in milliliters.

Does an electric motor turn faster if you increase the voltage? Voltage of the electricity used is measured in volts. Speed of rotation measured in revolutions per minute (RPMs)

How fast does a candle burn? Time measured in minutes. Height of candle measured in centimeters at regular intervals of time (for example, every five minutes)

A student wanted to test how the mass of a paper airplane affected the distance it would fly. Paper clips were added before each test flight. As each paper clip was added, the plane was tested to determine how far it would fly.

An experiment was performed to determine how the amount of coffee grounds could affect the taste of coffee. The same kind of coffee, the same percolator, the same amount and type of water, the same perking time, and the same electrical sources were used.

Four groups of similar-type rats are first massed and then fed identical diets except for the amount of vitamin A they receive. Each group gets a different amount of vitamin A. After 3 weeks on the diet, the rats’ masses are measured again to see if there has been a decrease.
