Learn about... One change in a variable can change the experiment.

Introduction
When you are conducting an experiment, the outcome will always change if one of the variables change. The experiment will always have an answer but unless you conduct the exact same experiment then the answer is different.

A change in a variable
When there is a change in a variable, everything changes in the experiment.

For example in the equation E=MC2 the m stands for mass and the C stands for Speed of light. Say the mass is 15, you take 15 and multiple that by C2 to get the energy. Then the mass changes to 20 the Varible M has changed to 20 grams from 15 grams. Then you take 20 grams and multiple it by C2 to the energy for 20 grams of mass.
