This site explains what can be learned from an ice core. Scientists collect ice cores by driving a hollow tube deep into the ice sheets of Antarctica and Greenland (and in glaciers elsewhere). The cylinders of ancient ice that they retrieve provide a detailed record of what was happening in the world over the past several ice ages. Each layer of ice in a core corresponds to a single year - or sometimes ... Full description.

This set of lecture notes discusses the occurrence and tectonic settings of igneous rocks near convergent plate margins. A discussion of petrography includes major element composition, calc-alkaline trends in ternary diagrams, trace element variations, isotopes to distinguish magma sources, and the origin of igneous rocks at convergent margins. The lecture notes include helpful illustrations, maps ... Full description.

This lesson explores the realm and limits of science. It engages students to give examples of topics that can be studied by science and those that cannot. It also takes a look at descriptive terms which reflect the true nature of modern science and those which do not, especially those which do not fit the popular perceptions of science.

This activity has students read and answer questions based upon the article 'The plate tectonic story: a scientific jigsaw.' The article starts with the continental drift theory of Alfred Wegener and adds the evidence from the seafloor to arrive at plate tectonics. It concludes with remarks about mantle dynamics and the future ability to predict earthquakes. Full description.

Most scientists agree that human activities are causing the global climate to heat up. However, in this radio broadcast, two scientists from Alaska explain how nature still has a big say in how much the Arctic heats up and that recent warming is part of a natural cycle, occurring over thousands of years. The clip from 2005 is 3 minutes and 54 seconds in length. Full description.
