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.
Space Weather Research Explorer
looks at how the sun creates a changing set of conditions in space. Learn about coronal holes, solar flares, coronal mass ejections, solar wind, magnetosphere, and auroras. See photos, graphs, and live data. Make your own space weather predictions.
Henry F. Owens, III, comments on the death of Levi Hart
Excerpt from the Say Brother program investigating the events the night Levi Hart, a 14-year-old African American youth from Roxbury, Mass., was killed in a police chase. Hart, and two other Roxbury youths had stolen and car. When the officers caught up to them, Hart was shot, arguably by Richard Bourque, in an act of police brutality. Hart family attorney, Henry F. Owens, III, talks about the treatment minorities receive on the criminal side of the court, and the belief police were not going to
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
The second Space symposium- learning spaces
This presentation discusses the various elements that deem enterprise education spaces as fit for purpose
How To Add Explosive Power To Your Soccer Moves
Soccer Coach Mike Hefron demonstrates how to add explosive power to your beat-the-man moves on the soccer field in just 6 weeks.
This 5 minute video shows various silly clips of cats and kittens, set to music. The video could be used as an introduction or hook to a story about cats with younger students. (5:04)
This report outlines the process and findings from an innovative project for students. This work was part of the curriculum and involved students working with West Yorkshire Police as part of the safer Leeds project in designing and making a film for students n crime prevention and personal safety in Leeds
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

Using Mass Balance to Understand Atmospheric CFCs
In this activity, students use an interactive online mass balance model to help understand the observed levels of chlorofluorocarbon CFC-12 over the recent past. They then explore the influence of post Montreal Protocol emission scenarios on future CFC levels and discuss the relevance of this to stratospheric ...
A Correlated History of Earth
This page describes a geologic timescale poster available for purchase. The site also contains an interesting essay: "A Galactic Orbit Model for Periodic Mass Extinction," discussing how clusters of impacts could cause periodic mass extinctions.
Live Stream of Polar Bear in Scandinavia
This is a live feed of a polar bear living Denmark. The article below it explains the situation and cause related to the baby polar bear. Students can view the bear cub in real-time! This can be used to compliment the Common Core Test Exemplar informational text Where Do Polar Bears Live?
SAMPEX - Yohkoh: Solar Modification of Relativistic Electrons in the Earths Radiation Belts
The Solar Anomalous and Magnetospheric Particle Explorer, SAMPEX, measures fluxes of energetic particles from the sun, the Earths magnetosphere, and cosmic ray sources over a broad range of energies. The four instruments aboard SAMPEX are the Low-Energy Ion Analyzer (LEICA), The Heavy Ion Large Telescope (HILT), The Mass Spectrometer Telescope (MAST), and the Proton-Electron Telescope (PET). The Soft X-ray Telescope on the Yohkoh satellite takes daily full-disk soft X-ray images of the Sun. Comp
