Hypotheses for Windmill Science Experiments for Kids

Linear Correlation Between Wind Speed and Electricity Generation

  • One potential hypothesis for a science experiment on wind speed is the idea that there is a linear correlation between the wind speed and the electricity generated by the windmill. When the wind blows very slowly, the windmill moves slowly and creates a small amount of electricity. When the wind blows quickly, the windmill moves quickly and creates a correspondingly larger amount of electricity. Test this hypothesis by setting up a anemometer (a wind speed meter) and checking the wind speed. Then check the amount of energy generated by the windmill. Compare the two on a line graph to see if the relationship is a linear one.

    Determine whether there is an exact linear correlation between wind speed and electricity generation.

Wind Direction and Electricity Generation

  • Another hypothesis to test is the idea that a windmill that is stationary will have an optimal wind direction. When wind blows in a specific direction, the windmill blades will move more quickly and the windmill will generate more power. When the wind blows from a direction that is less than optimal, the windmill will generate less power even though the overall wind speed might be the same. Test this hypothesis by determining what might be the optimal wind direction. Set up an anemometer in several locations. Place a weather vane near the windmill to determine wind direction. Track the wind speed and direction on a graph with the electricity generation to see if there is any correlation.

    Determine whether the relative wind speed impacts the electricity generation.

Rain and Electricity from the Windmill

  • In this hypothesis, test the idea that the weather can affect the amount of electricity generation. Test to see whether more electricity is generated on a sunny day than on a rainy, but equally-windy day. To test this hypothesis, set up an anemometer and a station to collect rainfall. Also track the amount of electricity generated. Track the rainfall, wind speed, and electrical generation on a graph to see if they are connected.

    Determine whether rainfall is a factor in electricity generation.

Gusting Wind and Electricity Generation

  • In this hypothesis, test the idea that consistent and sustained wind is better for electricity generation than gusting wind. To test this hypothesis, use a digital anemometer with a memory and place it outdoors near the blades of the windmill. Over a series of days, track the wind speed and duration of that speed. Determine what you deem to be a sustained wind and a gusting wind. Track the electricity generated and determine whether gusting wind or sustained wind is better for electricity generation.
