Cross bedding and ancient currents

Today's new ELI is the last in our current series of sedimentary structures. It is 'Cross bedding and ancient currents; using cross-bedding to find the directions of ancient currents' Cross-bedding is a common feature of sedimentary rocks. The formation of cross-bedding can be seen in modern depositional environments and then related to similar structures in sedimentary rocks – an example of using the present to help us to understand the past. Cross-bedding can be used as part of prospecting in the minerals or hydrocarbon industries.

Identifying minerals in the dark!

Have you tried 'Identifying minerals – use your sense(s)! Minerals in the dark: identifying minerals when the lights fail'  In this activity, pupils use their senses other than sight to enable them to identify a range of different minerals.
Lots more ideas on our website.

Cross-bedding and way-up structures

Today's new ELI is another in our series about sedimentary structures. This one 'Cross-bedding' uses cross bedding to determine the way-up of a bed of sedimentary rock. It gives an introduction to the types of evidence which can be obtained from cross-bedding in sediments and in sedimentary rocks.

Other activities to show sedimentary structures can be found in the link to Teaching strategies on our website.

Interactive hydrothermal mineralisation

Interactive hydrothermal mineralisation; 'the rock with the hole' hydrothermal mineralisation demo. This ELI+ activity demonstrates how hydrothermal minerals form. It could be used as a simple illustration of the processes with minimal pupil involvement. But it can also be used as an interactive demonstration, to engage pupils in the thinking behind a scientific enquiry.

There are many more mineral teaching ideas on our website under Teaching strategies.
