This activity uses photographs of metamorphic rocks used for ornamental purposes. This activity follows ‘Building Stones 1’ and is intended for pupils to deepen their understanding of metamorphic rocks. A table showing how the series of Earthlearningidea building stone activities link together is given on the final page.

This activity investigates the factors which affect the angle of slope at which materials fail and slip. It could be used in a lesson on slope failure itself, or as an application of the physics of friction.
This ELI develops an earlier teacher demonstration in 'Atmosphere and ocean in a tank'into a smaller-scale model for pupil group use.
It explains how warm ocean water, or warm air, rises upwards while cold ocean water or cold air, sinks. It then demonstrates how density currents flow in the water, or air, and can be used as an analogy of density currents in the oceans and atmosphere.

This activity introduces pupils to environmental sampling and density separation. It demonstrates how a saturated salt solution can be used to isolate microplastics from soil or sediment and shows how pollution can be studied using simple materials.
