a series of steps followed to solve problems
Hypothesis
an explanation that is based on prior scientific or observations and that can be tested
Controlled experiment
an experiment that test only one factor at a time by using a comparison of a control group with a experimental group
Variable
a factor that changes in an experiment in order to test a hypothesis
Control group
the group in an experiment or study that does not receive treatment by the researchers and is then used as a benchmark to measure how the other tested subjects do.
Experimental group
a group that receives a treatment in an experiment. The “group” is made up of test subjects (people, animals, plants, cells etc.) and the “treatment” is the variable you are studying.
