Move on to explain the concept of an experiment as it relates to the scientific method and explain the example of the experiment in "the paper towel theory." Demonstrate the experiment for the students.
Move on to explain the concept of a conclusion as it relates to the scientific method and explain the example of the conclusion in "the paper towel theory." Ask the students if the their hypothesis was supported by the experiment.
Goal: This lesson will teach students the purpose, application, and steps of the scientific method. Students will be able to apply the scientific method to everyday life situations to help them make decisions and predictions. Students will understand how scientists test hypotheses by using the scientific method. This lesson plan is intended for junior high students.
After reading the class notes on designing experiments, think about some example of pseudoscience or alternative science (astrology, palm-reading, accupuncture, intelligent design, echinacea, etc.) you've heard about, come up with a scientific hypothesis based on the idea and then design an experiment that could be done to test the hypothesis. Your experiment should have a clear question, a hypothesis, a prediction, and an experimental design that would test your prediction.
Move on to explain the concept of a hypothesis as it relates to the scientific method and explain the example of the hypothesis in "the paper towel theory." Ask the students which paper towel they think will absorb more water.
While it is the responsibility of the researchers to adhere to the scientific method, it is also possible to evaluate scientific findings and trace how the scientific method was used in experiments.
In this paper, the scientific method will be traced in an experiment involving mice and coffee, where the researchers were interested in the effect coffee consumption had upon mice that were genetically engineered to become diabetic....
The scientific method is employed when creating and executing an experiment. The purpose of the scientific method is to have a systematic way of testing ideas and reporting results in the process of scientific inquiry. A key component of the use of the scientific method is that it ensures that the experiment should be able to be replicated by anyone. If that is not possible, then the results are considered invalid.
The process of executing an experiment using the scientific method also ensures that data is recorded and able to be shared so that any bias on the part of the scientist performing the experiment can be reduced. Furthermore, the communication of the results allows for peers to review the work to ensure that the results are precise and accurate.
Move on to explain the concept of an observation as it relates to the scientific method and explain the example of the observations in "the paper towel theory." Pass the paper towels around to the students so they can observe the differences for themselves.
Teach the scientific method to your students through these ideas and science experiments! Check this out to learn more about how you can make the scientific method engaging!
CORRECTION: Perhaps because the Scientific Method presents a linear and rigid representation of the process of science, many people think that doing science involves closely following a series of steps, with no room for creativity and inspiration. In fact, many scientists recognize that creative thinking is one of the most important skills they have whether that creativity is used to come up with an alternative hypothesis, to devise a new way of testing an idea, or to look at old data in a new light. Creativity is critical to science!
Real scientists use a large varietyof methods (perhaps call them methods of science rather than "TheScientific Method.") Hypothesis / experiment / conclusion is one ofthese, and it's very important in experimental science such as physicsand chemistry, but it's certainly not the only method.
If "The Scientific Method"listed in a grade school textbook proves that Astronomy is not a science, then it's the textbook which is wrong, not Astronomy.
- Sir Peter MedawarThere are many parts of science that cannot easily be forced into the moldof "hypothesis-experiment-conclusion." Astronomy is not an experimentalscience, and Paleontologists don't perform Paleontology experiments...
