Harnessing the power of the Sun

The third in our 'net zero' Earthlearningidea series is 'Harnessing the power of the Sun; could solar farms be used in your area?'

Government ‘net-zero’ targets will affect many areas across the world. This Earthlearningidea explores what the impacts of building solar farms might be in your local area. 

Other mitigation and adaptation measures are discussed in other Earthlearningideas which can be accessed here.

Earth's spin and Earth's orbit

'A screaming roller coaster; how fast am I travelling (due to Earth’s spin and Earth’s orbit)?'


This activity gives a good introduction to the speed of the spinning and orbiting Earth. Other activities related to day and night and the seasons can be found on our website in the Earth in Space category.

Blue Hydrogen – the fuel of the future?

The next in our 'net zero' series is 'Blue Hydrogen – the fuel of the future? Could “blue” hydrogen be produced and used here?'

This activity gives an assessment of the potential of the North West of England region for the manufacture and use of hydrogen from natural gas. Making a clean fuel like hydrogen from a carbon-based fuel may seem counter-intuitive, but it is feasible if the waste carbon gases can be captured and stored safely below ground.

Relative dating - dating the Earth before radioactive dating

'Dating the Earth – before the discovery of radioactivity; Charles Lyell and Mount Etna, 1828'.


The activity provides an opportunity to use simple mathematics in solving a long-standing geological problem. Students should be made aware that the figures are extremely approximate, and that the activity is designed to show the principle behind Lyell’s approach, rather than providing an accurate value.

Other activities related to finding out the age of the Earth can be found in the Geological Time category on our website.
