Lost – a hot rock
In this activity, students examine an igneous rock and synthesise these observations into a poster that includes characteristic features of igneous rocks.
Pumice
Pumice, a rhyolite, is very common in the central North Island. It may still have evidence of the bubbles of gas trapped as the rock solidified.
By the end of this activity, students should be able to:
carefully observe rocks and carry out tests on them
identify the characteristics of igneous rocks
synthesise their investigations into a wanted poster.

Nature of science
Fieldwork is an important part of gathering evidence. Developing a poster provides an opportunity for students to be able to record their observations systematically.
