Generating Research Ideas

Idea 1- Comparing stored energy
-Measure a value: Experimental research
-In future, if we were to ever run out of fossil fuels, to have an alternate source of energy, we know what source of energy is the most reliable and provides the most fuel to sustain human life.In this experiment, we compare the different types of bio fuels for example: peanuts,wooden piece and wheat of the same size and the item that gives the highest temperature to the water contain the most amount of stored energy.

Idea 2- Water speed affecting the amount of energy the water wheel produces
- Measure a value: Experimental research
-Before there were engines and electricity, people used water to generate power.Water wheels use the energy of water moving downhill - a clean, renewable and green energy resource. We may build an overshot water wheel and observe how much weight it can lift when the water flows over the wheel at different speeds. We will change the water speed by pouring the water from different heights.

Idea 3- Investigation of how the shape of the blades affects the electricity produced by a wind turbine
-Measure a function or relationship: Experimental research
-The technology needed to gather energy from the wind has been around for a long time. For example, during the middle ages, windmills were used in Iran to grind corn and draw water from wells. We will build a wind turbine and make 5 different shaped blades for it. Then, we will measure the voltage produced by each,the one that gives the highest reading is the most efficient and green product to use.

The Scientific Method

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.


The 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:
    • 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.

The 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!
