Energy & Power

There are many different ways in which a rocket can be propelled, for instance by: air pressure, burning fuel or using water pressure as in the following experiment.

Elastic energy is the potential energy stored in a material when its shape is changed. This potential energy can be very useful when it is converted into other forms of energy, to do work, or have some fun with...

Many of the world's most powerful machines are driven by the power of water. In the days of our ancestors, falling water was used to drive water wheels to produce power for grinding grain. These days many natural forms...

Make a 'rotor-propelled' paddle boat that is driven by the elastic energy stored in a rubber band. In this science experiment we will learn how elastic energy is converted into kinetic energy. As the elastic energy in the rubber...

In ancient times, falling water was used to drive a type of turbine, called a 'water wheel' to produce power for grinding grain. The 'turbine' in this science experiment will be powered by water and gravity.

Two types of energy exist: kinetic energy is the energy of moving objects and potential energy is stored energy that has the ability to change into kinetic energy. Elastic energy contained in a rubber band is a type of...
