THE INCREDIBLE WAY TO GENERATE ELECTRICITY USING THE POWER OF NATURE!!
Power the digital clock using potatoes.
Help children to understand electrical principals.
Explore alternative energy in a fun way.
High voltage inspirational fun.
Suitable for children aged four and over.
Children will engage with the science without it being a school like or hard work, helping them to fully understand the importance of protecting the environment around them and alternative sources of energy. No batteries are required for this working clock. Be a scientist and discover how to power this digital clock using potatoes. Be amazed as you experiment with other substances to power the clock.
How it works:
The metal strips and potato make a simple battery that creates electricity to operate the clock. Each potato works as a device called an electrochemical cell. It converts the chemical energy stored in the metal strips into electrical energy. Two potatoes are needed to make electricity strong enough to run the clock.
A cell works because of the chemical properties of the metals inside (in this case the copper and zinc). The different properties cause tiny particles charged with electricity (called ions) to move between the two strips of metal. This flow is an electric current. The potato contains the particles that allow the current to flow, but it stops the metals touching. Electric current also flows along the wires between the zinc and copper strips and the clock. This current makes the clockwork.
You may experiment with different liquids like salt water, fruit juices. Or fruit like lemon, orange, tomato, etc.
Taking care that the metal plates do not touch each other.
