Objects of Devotion - Ex Votos
An earthquake ravages a small town in central Italy. Catastrophic fissures rip through the buildings; desperate cries can be heard from those whose houses are collapsing; others try to attract attention by standing on rooftops and waving their hands but to no avail. Only one home stands firm while the buildings all around it crumble to the ground. Here, the Viadana family kneels in quiet prayer; husband, wife and four sons, all neatly attired and strikingly tranquil amid the chaos, appeal to the

Battle of the Little Bighorn - Part 4
This 9:39 long video does an excellent job of recreating the battle using evidence from the Little Bighorn battlefield that suggests
that members of the 7th Cavalry may have retreated in panic at "Calhoun Hill."Eyewitness testimony, from the warriors, indicates the cohesiveness of Custer's fighting units changed at Little Bighorn. Those observations are also confirmed by the physical evidence. At some point during the battle, Custer's troops moved from "tactical stability to t
Evaluation de l'enseignement et accompagnement pédagogique à la FSA de l'Université de Laval
Le processus d’évaluation de l’enseignement utilisé à la Faculté des sciences de l’administration (FSA) de l’Université Laval - forte d’une longue expérience dans ce domaine sera présenté et discuté : questionnaires d’évaluation utilisés afin de faire ressortir les éléments qui sont valorisés, puis rapports produits et rôle des différentes personnes ayant accès à ces rapports (enseignant, directeur de département, vice-doyen à la formation, conseillère en pé
The Politics of Johann Wolfgang Goethe [A version of this was published in The Wall Street Journal Europe, December 30, 1999.] This year marks the 250th birthday of Johann Wolfgang von Goethe. Most Europeans know that he was the greatest of all German writers and poets and one of the giants of world literature. Less well known is that he was also a thorough-going classica
Inflation Targeting Hits the Wall The financial-market crisis is not over but has grown into a vicious sovereign-debt crisis. Nevertheless, monetary policy makers of the major economies go on to practice the same sort of policy that has led to the crisis. Following the model of inflation targeting, they continue to disregard the quantity of money and the amount and kind of credit creation. As they did before, central banker
Colorado Water Knowledge
The Colorado Water Knowledge Web site is maintained by the Colorado State University Colorado Water Resources Research Institute. The site allows kids to explore all aspects of water science including general facts, a description of the water cycle, stream processes, Colorado geology and water history, major aquifers of the area, aquatic life in local waters, Colorado water laws and regulations, and much more. Although it isn't graphic intensive, the site does a good job of explaining the wide a
DNA from the Beginning: An Animated Primer on the Basics of DNA, Genes and Hereditary
Maintained by the Cold Spring Harbor Research Laboratory and the Josiah Macy, Jr. Foundation, this animated DNA primer (last mentioned in the February 19, 1999 Scout Report) now has three major sections -- Classical Genetics, Molecular Genetics, and Genetic Organization and Control. Each section covers several concepts by description and in animation, along with interviews and biographies of scientists, a quiz to test your understanding, and related Web links. This is a well-organized site with
Digging into Minnesota Minerals
The Digging into Minnesota Minerals Web site is part of the larger Minnesota State Department of Natural Resources site. These fun and interesting pages explain how Minnesota came to acquire its most common minerals over geologic time, what the basic types of rocks are, mining history of the state, the geology found in state parks, and much more. Included are basic descriptions, photographs, illustrations, and even educational activities for teachers related to the minerals. This well-designed s
EuroHaptics 2003
Haptics is the science of incorporating touch and physical stimuli into computer applications. A haptics interface can allow the user to feel responses from a program, thereby providing an additional level of perception in a virtual environment, for example. This site hosts the proceedings of the 2003 EuroHaptics conference. Over 30 papers and several more poster presentations are available, spanning the areas of interaction, hardware, algorithms, and psychophysics. Proceedings of the 2001 and 2
Yeast Cells Respire, Too (But Not Like Me and You)
Students set up a simple way to indirectly observe and quantify the amount of respiration occurring in yeast-molasses cultures. Each student adds a small amount of baking yeast to a test tube filled with diluted molasses. A second, smaller test tube is then placed upside-down inside the solution. As the yeast cells respire, the carbon dioxide they produce is trapped inside the inverted test tube, producing a growing bubble of gas that is easily observed and measured. Students are presented with
Topo Triangulation
In this activity, students will learn how to read a topographical map and how to triangulate with just a map. True triangulation requires both a map and compass, but to simplify the activity and make it possible indoors, the compass information is given. Students will practice converting a compass measurement to a protractor measurement, as well as reverse a bearing direction (i.e., if they know a tree’s bearing is 100 degrees from you, they can determine what bearing they are from the tree).
River Flow Rate
In this activity, students utilize their understanding and feel for flow rate from the Faucet Flow Rate activity to estimate the flow rate in a local river. The objective is for students to relate laboratory experiment results to the environment. Students will then use the Engineering Our Water Living Lab (accessible through TeachEngineering.com) to determine the actual flow rate data for their chosen river. They will compare their estimate with the actual flow rate. Note: for this activity to b
Lights Out!
This lesson introduces the concept of electricity by asking students to imagine what their life would be like without electricity. Two main forms of electricity, static and current, are introduced. Students learn that electrons can move between atoms, leaving atoms in a charged state.
Solar Power
In this activity, students learn how engineers use solar energy to heat buildings by investigating the thermal storage properties of some common materials: sand, salt, water and shredded paper. Students then evaluate the usefulness of each material as a thermal storage material to be used as the thermal mass in a passive solar building.
Pointing at Maximum Power for PV
Student teams measure voltage and current in order to determine the power output of a photovoltaic (PV) panel. They vary the resistance in a simple circuit connected to the panel to demonstrate the effects on voltage, current, and power output. After collecting data, they calculate power for each resistance setting, creating a graph of current vs. voltage, and indentifying the maximum power point.
Oceans, climate and weather
What is the difference between weather and climate? What do the oceans have to do with them? Weather is the day-to-day state of the atmosphere and its short-term (minutes to weeks) variation. Climate is typically described by the regional patterns of seasonal temperature and precipitation over 30 years. The averages of annual temperature, rainfall, cloud cover, and depth of frost penetration are all typical climate-related statistics. The oceans influence the worlds climate by storing solar ener
How Do Seasonal Temperature Patterns Vary Among Different Regions of the World?
The purpose of this resource is to have students use GLOBE visualizations to display student data on maps and to learn about seasonal changes in regional and global temperature patterns. Students learn how sunlight spreads over the Earth at different times of the year, emphasizing the solstices and the equinoxes. Students investigate the effect of the Earth.s tilt on the spread of sunlight by modeling different tilts using a three-dimensional polyhedron which they construct from paper. Students
What Is Energy? Short Demos
Three short, hands-on, in-class demos expand students’ understand of energy. First, using peanuts and heat, students see how the human body burns food to make energy. Then, students create paper snake mobiles to explore how heat energy can cause motion. Finally, students determine the effect that heat energy from the sun (or a lamp) has on temperature by placing pans of water in different locations.
