The Scientific Method is a way to ask and answer scientific questions by making observations and doing experiments.

The steps of the scientific method are to:

• Decide what you already care about
• Ask a question
• Do background research
• Construct a hypothesis
• Test your hypothesis by doing an experiment
• Analyze your data and draw a conclusion
• Communicate your results

It is important for your experiment to be a fair test. A “fair test” occurs when you change only one factor (variable) and keep all other conditions the same.

If your project involves creating or inventing something new, your project might better fit the steps of the Engineering Design Process.

The Engineering Design Process is the set of steps that a designer takes to go from identifying a problem or need, to creating and developing a solution that solves the problem or meets the need.

The steps of the Engineering Design Process are to:

• Define the problem
• Do background research
• Specify requirements
• Create alternative solutions
• Choose the best solution
• Do development work
• Build a prototype
• Test and redesign

During the Engineering Design Process, designers frequently jump back and forth between steps. Going back to earlier steps is common. This way of working is called “iteration,” and it is likely that your process will do the same!

Remember: While engineers create new things — such as products, websites, environments and experiences — scientists study how nature works. If your project involves making observations and doing experiments, your project might better fit the Scientific Method.

Category Selection
Many projects could easily fit into more than one category. It is the student’s decision to choose the category that most accurately describes their project but they will need help.
Ask the following questions to help in the selection of a category:
Who will be the most qualified to judge the project? What area of expertise is the most important for the judge to have? (For example: a medical background or an engineering background.)
What is the emphasis of the project? What characteristic of my project is the most innovative, unique or important? (For example: Is it the application in medicine or the engineering of the machine? Is it inserting the proper gene, or the method of computer mapping to demonstrate the results?)

Category Selection
Selecting a category at this level can be difficult for some. Many projects could easily fit into more than one category. It is students’ decision to choose the category that most accurately describes their projects, but at the elementary level they will definitely need help.
Ask the following questions to help in the selection of a category:
Who will be the most qualified to judge the project? What area of expertise is the most important for the judge to have? (For example: a medical background or an engineering background.)
What is the emphasis of the project?

You can ask the student what characteristic of their project is the most innovative, unique or important. (For example, is it the application in medicine … or the engineering of the machine? Is it inserting the proper gene, or the method of computer mapping to demonstrate the results?)
