The experimental group. com's team of professional scientists, science teachers, and educational consultants has put together a fantastic collection of free life science fair projects, life science experiments, and biology science fair projects for kids. — Benjamin Toff, Washington Fusion power is a theoretical form of power generation in which energy will be generated by using nuclear fusion reactions to produce heat for electricity generation. Scientific experiments typically involve a number of variables: Independent variable; Dependent variable; Controlled variable; An independent variable is one that is changed by the scientist in order to facilitate an action or reaction within the given experiment. The harder and more intriguing the initial question is, the better the resulting investigation and experiment will be. Every kid is for rainbows, explosions, or rainbow explosions. An independent variable (also called a factor) is an explanatory variable manipulated by the experimenter. Is your test a ‘fair test’? Is your test a ‘fair test’? Sometimes experiments don’t always give the same results when repeated. Francesco Redi was able to disprove the theory that maggots could be spontaneously generated from meat using a controlled experiment.

The control in the experiment is the group of items that is "normal" basically what the experiment is compared against. to exercise restraint or direction over; dominate; command: The car is difficult to control at high speeds. They get us away from objects that might hurt us, before they hurt us. The independent variable is what the scientist manipulates in the experiment. Coming up with a creative idea and then figuring out how to turn that idea into an experiment or demonstration can be tricky. The scientific method is an integral part of science classes. In other words, it is a possible independent variable that the scientist has no interest in investigating. Both plants need to be planted in the same size pot, using the same type of soil and the same amount of soil. While test subjects and theories constantly change, all science experiments must be executed in a similar manner, with control measures In this type of experiment everything needs to stay the same except one variable. Controlled variables must be carefully monitored and kept equal in your experiments - otherwise they could mess up your experiment by making your results false or unreliable.
