The ELI today continues our theme of geological (deep) time with 'But how old is it? Investigating radioactive dating of rocks and minerals'.
This activity investigates how radioactive (radiometric) or absolute dating of rocks and minerals works.

Continuing our theme of geological time, the ELI today is 'The origin of the Earth – at arm’s length: the age of the Earth - with a good stretch of imagination.'
This activity teaches the great length of geological time in a fun way. It could be used to reinforce other methods of helping pupils to understand the concept of “deep time”, e.g. during a quick-fire revision session.

For the next few weeks, we will be considering geological time. The ELI today is 'The toilet roll of time; make a geological timeline to take home'.
This activity has been devised to address the common lack of knowledge about geological time. Research has shown that many people have no idea of the great length of geological time nor of the order of the key events during the geological history of the Earth.
