Exploring Energy

Build your own Energy Transformer

Here are some starter ideas for mainly easy to build projects that help you explore the different types of energy and how you can use it. It will help you understand how the science of energy transformation is behind all of the greatest and coolest inventions !

The famous and never-ever broken Law of Conservation of Energy says that:

"Energy can never be created or destroyed, it can only be transformed from one kind into another. "

Once you have an idea of how energy transformation works you can use your imagination to be really innovative and come up with a super new invention you and your friends have never even dreamed of before!

Energy transformations done by the experiment

Sun light (Solar)

Radiant energy

  • Radiant -> heat
  • Radiant -> electric -> chemical energy
  • Radiant -> heat -> gravitational

Hydro

(water at height)

Gravitational potential energy

Gravitational > kinetic -> rotational kinetic

Wind

(moving air)

Kinetic energy

Kinetic -> rotational kinetic

Elastic/spring

Elastic Potential energy

Elastic -> kinetic

Compressed air

(pressure)

Elastic Potential energy

Elastic -> kinetic -> gravitational

Fuel

Chemical potential energy

  • Chemical -> heat -> pressure -> kinetic energy
  • Chemical -> heat -> kinetic energy -> gravitational

Battery

Chemical potential energy

Chemical -> electric energy

Electricity

Electric energy

  • Electric ->kinetic energy
  • Kinetic -> electric energy

Gravity

Gravitational potential energy

Kinetic -> gravitational -> kinetic

Biomass

Chemical potential energy

Chemical -> heat energy

Heat

Heat energy

Heat -> electric -> kinetic energy

 

  • Remember that some of these activities can be dangerous, esepcially those involving fuels, heat, and fast moving objects- so be careful and follow safe practices !
  • Keep in mind that it is the time-honoured New Zealand way to invent and build stuff using materials at hand- the number eight wire approach aka "kiwi ingenuity". Its also very green to recycle and reuse old stuff that would otherwise go to the dump.
