Literature Review (Beverly Heng)

Research Question
How does the material of the flexible skirt affect the performance of a hoverboard?

Literature Review

According to O.G READMORE (2007), a flexible skirt of a overboard acts like an airbag to help trap air under the board and increase efficiency. The “real” hoverboard’s skirt is made of a plastic sheet (Tech-FAQ, 2012).

Engineering Method

  • The engineering design process is a series of steps that engineers follow to come up with a solution to a problem. Many times the solution involves designing a product (like a machine or computer code) that meets certain criteria and/or accomplishes a certain task.
  • The steps of the engineering design process are to:
    • Define the Problem
    • Do Background Research
    • Specify Requirements
    • Brainstorm Solutions
    • Choose the Best Solution
    • Do Development Work
    • Build a Prototype
    • Test and Redesign
  • Engineers do not always follow the engineering design process steps in order, one after another. It is very common to design something, test it, find a problem, and then go back to an earlier step to make a modification or change to your design. This way of working is called iteration, and it is likely that your process will do the same!

Scientific Method

  • 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:

  1. Ask a Question
  2. Do Background Research
  3. Construct a Hypothesis
  4. Test Your Hypothesis by Doing an Experiment
  5. Analyze Your Data and Draw a Conclusion
  6. 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.

            What is Science?

            Science is the concerted human effort to understand, or to understand better, the history of the natural world and how the natural world works, with observable physical evidence as the basis of that understanding. It is done through observation of natural phenomena, and/or through experimentation that tries to simulate natural processes under controlled conditions.
