This site describes bouyancy (the difference between the upward and downward forces acting on the bottom and the top of an object) and the Archimedes Principle, which states that the buoyant force on a submerged object is equal to the weight of the fluid that is displaced by it. It consists of text descriptions of these principles, using the examples of metal cubes suspended in water and hot air baloons ... Full description.

In this activity, students learn to recognize periodicity within a set of data by using the examples of pendulums and binary star systems. Included are prerequisites, enrichment activities, materials lists, datasets, instructions, and links to additional information.. Full description.

This document discusses the history of mass extinctions throughout geologic time, their role in the evolutionary process, and a mathematical model that demonstrates how the evolutionary process might interact with environmental stresses to produce a distribution of extinctions similar to that seen in the fossil record. Full description.
