A controlled experiment the process scientists use to answer a question or go about solving a scientific problem containing a control, variable, and constants to compare the results to.
The above picture shows you what a control is, exhibits a gradual change in the dependent variable, illustrates the results of this modification, displays how long the experiment has been taking place, and is a great way to display data.
Note: Green dots are germinated plants and brown aren't germinated
*An Example of the Entire Controlled Experiment Can Be Found Here:
1. What was the control group?
2. Why is this the control?
3. How can this experiment be bettered?
4. Why do you think the results were what they were?
5. Was your hypothesis correct? Why or why not?
Steps in the Controlled Experiment
Ask a Question
Form a Hypothesis
Create a Lab Procedure (Observe Safety Procedures and Include Control/Variable)
Conduct the Lab
Compare to Hypothesis
Draw a Conclusion
- The constant(s) or factor(s) that remain the same and don't change throughout the experiment. These are not manipulated as to extract the effect of the dependent variable properly and ensure accurate results
This is the factor that the conductor of the experiment will change and manipulate throughout the experiment to determine its affect on the subject and to better understand its role in the experimental situation
The part of the experiment that is left how it would be naturally, lacking the dependent variable. This group is a standard that each of the subjects can be compared to to understand the dependent variable's affect on them
The thought or expected outcome of an experiment. It is important to make a hypothesis to compare to the results so the conductor of the experiment can better interpret what the results mean and their significance in the experiment. If a hypothesis is proven wrong, it is important for the scientist to form a new hypothesis and redo the experiment to ensure accurate results
The necessary objects or subjects used in the experiment
The outline or plan of what you will do and what the experiment will consist of
The final result or outcome of the experiment (includes any data collected)
Why Do We Follow the Controlled Experiment?
Keeps procedure organized
Simplifies the gathering of results
Ensures safety in lab
Makes results more reliable and accurate
Provides specific and necessary results
Uses one variable at a time
