1. For this science fair project, the independent variable is the size of the propeller blades. The dependent variable is the speed at which the boxes move as a result of the thrust that is generated by the propeller. This is measured by recording how long it takes for the shoe box to travel 2 meters. The constants (control variables) are the power of the motor, the angle of the blades, the size of the box and the distance covered by the box. 2. Using a hacksaw, slots at 20 degrees are cut into the sides of 3 wooden ..... |
