Science is for ALL students. Whether students have learning problems or physical challenges, they should be able to experience hands-on science with their fellow classmates. This activity will introduce you to the concept of variables.
Scientists test their ideas by conducting experiments.
Every time scientists do experiments, they must look for variables. A variable is any factor in an experiment that affects the results. An independent variable is the part of the experiment that the scientist can control. For example, you may want to see if plant food makes a plant grow faster. You would then take 2 plants of the same size and give one plant food.
