Map that Habitat
Historically, sea floor mapping occurred with a more simple data collection method: soundings. Soundings are taken by dropping a weight with a pre-measured rope off the side of the boat and noting the measurement on the rope when the weight hits the bottom. This activity will replicate the creation of sea floor bathymetry by taking a simplified form of soundings in the classroom.
Rocks, Rocks, Rocks
Student teams will test rocks to identify and record rock properties such as luster, hardness, color, etc., and classify rocks as igneous, metamorphic and sedimentary. They will complete a worksheet table with all of their rock properties, and then answer some worksheet questions to deepen their understanding of rock properties and relate them to the cavern design problem.
Testing the Caverns - Optional
This activity provides a fun, activity-based closure to the Asteroid Impact unit. Students build model caverns using paper mache or clay and bury them in a tray of sand. Next, they test the models by dropping balls onto them to simulate an asteroid hitting the earth. By molding paper mache around a balloon to form a dome, or around a small cardboard box to form a rectangular structure, students will be able to build their caverns.
What's the Problem?
Lesson 1, Activity 1 introduces the Asteroid Impact unit. Students will read the President’s memo to receive their ‘marching orders’. Student teams are then formed and are given the student packet that includes worksheets and maps. Each team should become familiar with the maps and complete Worksheet One as a group.

Useful tricks and tips are provided as well as information on web browsers, the main features of a browser window, how to look at websites, using hyperlinks, searching for information on the internet, copying text, avoiding computer viruses, and using PDFs.
Losing the Business: The Donners Recall the Great Depression
Created in 1935, the Works Progress Administration (WPA) provided hope and employment for millions of unemployed workers and studied the human toll of the depression. One such study--a series of WPA-conducted interviews with Dubuque, Iowa families--found that middle-class Americans particularly felt the sting and shame of unemployment caused by the depression. In this interview, the Donners discussed the closing of their family-owned printing business in Chicago during tough times. Returning to

1.1.8 Surgical removal of tattoos
This Unit will introduce you to a number of ways of representing data graphically and of summarising data numerically. You will learn the uses for pie charts, bar charts, histograms and scatterplots. You will also be introduced to various ways of summarising data and methods for assessing location and dispersion.
4.4 Genetic diversity and mass extinctions
To be able to understand the importance of the environment for our health, we need to know a little about the interdependence between environment and humankind. This unit will look at interactions between plants, animals and the physical and chemical environment, as well as considering ways in which humans have altered, and are altering this environment. These changes have health implications that are not always immediately obvious. Frequently, we initiate changes that are going to have their ef

Michael Adams on The Boomer Impact
Environics co-founder, leading pollster, and author, Michael Adams, delivers a lecture on the Boomer Impact, drawing on the insights and research in his latest book Stayin' Alive: How Canadian Boomers Will Work, Play and Find Meaning in the Second Half of Their Adult Lives. This lecture was produced in collaboration with the Literary Review of Canada.
Nasdaq makes rival bid for NYSE

When Computers Changed the World from the Revolution Exhibition
"When Computers Changed the World" is just one of more than 100 videos in the Computer History Museum's new exhibition: "Revolution: the First 2000 Years of Computing." In the span of a single lifetime, computers have gone from large, incredibly expensive and rare devices to small, low-cost, ubiquitous tools that we can't imagine living without. Yet, few people know the history of how this came to be. Revolution: The First 2000 Years of Computing is a rich, multimedia exhibition that traces the
Handbook of Operational Amplifier Applications
The Handbook of Operational Amplifier Application is a complete and exhaustive compendium of Op Amp information. Chapters start with the basic electronics of the internal circuitry of op amps, feedback and analysis of operation followed by ideal and practical op amps. The remaining chapters provide numerous application circuits.
A Pictorial Representation of Product Operator Formalism: Non-Classical Vector Diagrams for Multidim
This site presents a pictorial description of the product operator formalism using a non-classical vector approach. This approach allows for the representation of any arbitrary multidimensional or heteronuclear NMR experiment. A description of a complete set of 16 vector representations for weakly-coupled two-spin (I=1/2) systems is given followed by an extension of this set to three-spin systems. Finally the concepts of coherence transfer, multiple quantum spectroscopy and phase cycling are ill
Green Chemistry (2nd edition)
Measurement science used to characterize environmentally important species is a central aspect of this textbook and accompanying lecture support/PowerPoint presentations. In addition to discussing the hows and whys of measurement, the discussion of measurements up to 2007 as related to the future of the environment provides a context for learning the material.
Principal Component Analysis
This site provides an introduction to principal component analysis, beginning with a glossary of important terms before taking the reader through the process of completing a principal component analysis. One limitation to the site is its reliance on Minitab and SPSS for calculations. Users without access to these programs can reproduce the calculations using other software packages, such as the freeware program R. Prior knowledge of basic statistics is assumed; thus, the site is most appropriate
Virtual Crime Scene-Autopsy of a Murder
This site is designed to explore the interaction of crime scene investigation and forensic science Visitors are taken to a crime site where a murder took place. Relevant items of physical evidence are identified and the viewer is allowed to transport each item into a virtual crime. In the laboratory the viewer is allowed to select the appropriate technology to examine the selected item of evidence. Explanations are provided to educate the viewer on the theory and applications of a variety of for
Cooperative Learning, Values, and Culturally Plural Classrooms
This webpage provides an introduction to cooperative learning by David and Roger Johnson who developed the technique. The article provides an overview of the cooperative learning method, discusses its educational benefits, and provides assessment data for its efficacy. The article also provides archival references to their work and others. As such the article is an invaluable resource for faculty interested in developing and implementing cooperative learning activities in their own classrooms
