The fastest CME of Cycle 23 overtakes another fast CME
On November 4, 2003, the Sun produced its fastest coronal mass ejection (CME) for cycle 23 out of the active region 0486 located near the southwest limb of the Sun. The CME was expelled with a speed of approximately 2700 km-s. At the time of the launch of this CME, there was another ejection in progress ...

Soil Particle Density Protocol
The purpose of this resource is to measure the soil particle density of each horizon in a soil profile. Students weigh a sample of dry, sieved soil from a horizon, mix it with distilled water and then boil the mixture to remove any air. The mixture cools for a day and then students add water until the volume of the mixture is 100 mL. Students measure the temperature and mass of the final mixture and use the Soil Particle Density Data Sheet to calculate the soil particle density. Three samples sh

Gravimetric Soil Moisture Protocols
The purpose of this resource is to measure soil water content by mass. Students collect soil samples with a trowel or auger and weigh them, dry them, and then weigh them again. The soil water content is determined by calculating the difference between the wet sample mass and the dry sample mass.

GEOLogic: The Big Five Mass Extinctions
GEOLogic questions are puzzles that were developed to support students understanding of geoscience concepts while challenging them to develop better logic and problem solving skills. In this exercise, students are asked to match up the five largest mass extinction events with their relative dates, approximate duration, and severity (percentage of species that became extinct) based on clues given from various perspectives. This activity is appropriate for a high school science class or an introdu

Viscosity of the Mantle: Constraints from Post-glacial Rebound
In this lab, students determine the viscosity of a relatively viscous fluid by measuring the rate of rebound of a partially submerged object following a rapid decrease in its mass. This experiment is carried out in the context of an analysis of post-glacial rebound as a measurement of the viscosity ...

Were Dinosaurs Cold- or Warm-Blooded?: An Exercise in Scientific Inference
Both metabolic rates and brain masses are approximately 10 times as great in modern terrestrial warm-blooded animals (birds and mammals) as in cold-blooded terrestrial animals (reptiles) of the same body mass. This is one of several lines of evidence scientists have used to infer the mode of thermal regulation of dinosaurs and other extinct amniotes. In this exercise each student is assigned one of a number of dinosaurs. Students estimate brain mass from a drawing of a cranial endocast and body

Living in an Era of Global Terror
In this podcast, Professor Richard Aldrich from the School of Politics and International Relations, discusses the impact of globalisation, the opportunities this affords to global terrorists and the challenges faced by the intelligence services. Globalisation has led to a free flow of money, people and ideas, which has benefited many people in the West in recent years and enhanced our standard of living, but the price paid is a reduction in security. As we see a shift towards a de-regulated glo

The Genesis of the 1918 Spanish Influenza Pandemic
Michael Worobey, Professor, Ecology and Evolutionary Biology, The University of Arizona The Spanish influenza pandemic of 1918 was the most intense outbreak of disease in human history. It killed upwards of 50 million people (most in a six-week period) casting a long shadow of fear and mystery: nearly a century later, scientists have been unable to explain why, unlike all other influenza outbreaks, it killed young adults in huge numbers. I will describe how analyses of large numbers of influenz
