The hypothesis is that a trapezoid shaped blade at 75 degrees with the largest surface area will generate the greatest amount of electricity.

You will build a windmill, attach a motor to it, and measure the electricity produced with an amp meter. You will also cut out blades in different shapes and sizes and attach them to the windmill.

You will need a windmill, an amp meter, a fan, a tape measure, an electrical motor, and 24 blades in different shapes and sizes.

The results showed that the trapezoid blades with an area of 98cm2 at 75 degrees produced the most electricity. Even though the trapezoid shape was the most efficient, the other blade angles and surface areas may be better shapes for a windmill.

This science project is interesting because it helps us understand how different blade designs can affect the amount of electricity produced by a windmill.

Consider testing different blade angles and surface areas to see if they produce more electricity than the trapezoid shape. Also, consider testing different wind speeds to see how it affects the electricity produced.
