What’s it about?

The air that surrounds us is a gas. Gasses and liquids are both considered to be ‘fluids’, meaning that they flow and can change their shape easily. Air contains small particles called ‘atoms’ that can move around freely to change shape and fit a certain space. We cannot see the air, but we can feel the wind on our bodies and see it blowing through trees. In this science experiment, let’s build a ‘rotor’ to observe how the wind affect it:

Topics covered

Rotor, Fluid, Kinetic energy, Leonardo da Vinci

How does it work?

Unfortunately, this section is only available in the e-book version of the project.

This science experiment works because the rotor use kinetic energy of the air to turn or do ‘work’. Kinetic energy is the energy of moving objects. The kinetic energy of the moving air turns the blades of your rotor.
