Identifying rocks when you're out and about

 If you are out for a walk and see some rocks, do you wonder what they are? Here are some questions to ask yourself, 'Questions for any rock face 4: rock group (sedimentary or igneous): what questions about the type of rock might be asked at any rock exposure?'

This field activity helps people to ask questions to help distinguish between sedimentary and igneous rocks. There are many Earthlearningideas about asking questions when looking at rocks. They can be found in 'Fieldwork' in our Investigating the Earth category.
   

Flood through the window

Following the devastating effects of the floods in Texas, our ELI today is 'Flood through the window - what would you see, how would you feel? Pupils picture for themselves what a major flood through the window might look like.'


This activity encourages pupils to really think about flooding and what it would be like to be caught in a sudden flash flood. The ELI gives a series of questions to help pupils realise the effects and their possible consequences.

Related activities can be found in our Natural Hazards category.

   

Relative dating of rocks

Our new ELI today is '‘Photo dating’; using photos to simulate the relative dating of the rock record.'

This activity has been devised to demonstrate the principles behind relative dating using zone fossils by substituting photographs, taken over a period of time within the experience of the students.

Related activities can be found in our Geological Time category.

   

Geological time

We continue our series investigating geological time with '‘Looking so far into the Abyss of Time’; how to visualise the immensity of geological time...with a rope!'.


This ELI is an exercise to demonstrate the extent of geological time-scales and the need for meaningful geological reference points, obtained from fossils and other geological events, recorded in the rock record.

Go to 'Visualising deep time' in our Geological Time category for other related activities.

   

How do we know the actual age of rocks?

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.

Related activities can be found in our Geological Time category - Visualising deep time.
