Swinging Pendulum (for High School)
This activity shows students the engineering importance of understanding the laws of mechanical energy. More specifically, it demonstrates how potential energy can be converted to kinetic energy and back again. Given a pendulum height, students calculate and predict how fast the pendulum will swing by using the equations for potential and kinetic energy. The equations will be justified as students experimentally measure the speed of the pendulum and compare theory with reality.
3.5.3 Address resolution on LANS A host finds the hardware address that corresponds to an IP address by referring to a look-up table that contains the translation between the two types of address. The look-up table could be maintained manually by a network administrator, but this would be very slow. A far better solution is for the host to maintain the table automatically. Whenever a host has to send a datagram to an unknown IP address it sends a message to all the other hosts on the LAN. The host that recognises the IP addr
2.3 Newsgathering and newspapers
BBC News 24, Sky News, CNN – we live in an era where news has become almost instantaneous. This unit will look at how news is gathered and the technology used for its dissemination. You will also be encouraged to examine how information might be manipulated by questioning its reliability.
Plates on the Move
This fun Web article is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they learn about the Earth's outer shell and its constant movement. It begins with an overview that explains tectonic plates and the four things (slip, spreading, collision, and subduction) that can happen when the edges of the plates meet.
Experimental Evaluation of Community Structure In Aquatic Ecosystems
A laboratory exercise to introduce a number of models of aquatic ecosystem community structure and their primary assumptions, analysis collected samples and make predication generated from each model
Population Density: How Much Space Do You Have?
Students learn about population density within environments and ecosystems. They determine the density of a population and think about why population density and distribution information is useful to engineers for city planning and design as well as for resource allocation.
Frogs
Lesson plan with word search activity which aims to teach children about the metamorphosis and development of an amphibian from tadpole to frog.
Oricalco - thermal shape memory fabric
The first orthogonal weaving example of Nitinol. The 'Thermal Shape Memory Alloy' is characterized by its extraordinary ability to recover any shape, pre-programmed, upon heating. Until today this light weight alloy with about 50% Titanium inside has been used in advanced sectors like space and recently in medical applications. Moreover this fabric is the first for which the shape memory alloy, named Nitinol, was weaved orthogonally that is to say that Oricalco is the first fabric with shape mem
Mitochondrial DNA Launois-Bensaude's Lipomatosis
Even though Brodie is said to have first described diffuse symmetrical lipomatosis with predilection for the neck already in the 1846 (Clinical Lectures on Surgery, Delivered at St. George's Hospital Philadelphia: Lea and Blanchard pub. Pp 201-201. Brodie, B.C.) the pathogenesis of Launois Bensaude' Lipomatosis is still unknown.
Obtaining SNPs from UCSC Table Browser
A quick tip of the week on how to obtain a list of SNPs and data for a gene of interest quickly from the UCSC Table Browser
Preservation of adaptive plasticity across scales of biological organization: from molecules to soci
This webcast outlines why and how adaptive plasticity is maintained at each and every scale of biological organization
Potatoes vs. Late Blight: Plants at War and Peace
Plant genome research is already revolutionizing the field of biology. Currently, scientists are unlocking the secrets of some of the most important plants in our lives, including corn, cotton and potatoes. Secrets of Plant Genomes: Revealed! takes viewers on a lively, upbeat journey that explores how these plants got to be the way they are and investigates how we can make better use of them in the future. Plant scientists are hard at work--in the lab, in the field and at the computer--to increa
"On the Night When the Levee Broke": William Cobb Remembers the 1927 Mississippi Flood
In spring 1927 it started raining in the Upper Midwest and, according to one observer, "it just never did stop." Torrential rains quickly filled the Mississippi's dozens of tributaries. On April 21, the supposedly impregnable levee system, maintained since 1879 by the Mississippi River Commission, sprang two leaks, or "crevasses" as they are known. Within days the Mississippi River levee system sustained forty more major crevasses in Arkansas, Mississippi, and Louisiana, unleashing a natural dis
"Human Rights are Women's Rights and Workers' Rights are Women's Rights:" May Chen on the United Nat
The United Nations Fourth World Conference on Women was held in Beijing, China during September 1995. The conference, which called for gender equality, development, and peace, grew out of the international women's movement and marked the end of the official United Nations decade of Women. For women like May Chen, Vice President of the Union of Needletrades, Industrial, and Textile Employees (UNITE), the conference was an opportunity to share their activist experiences and learn about issues conf
Inherited traits
Developed for the second grade. Learning intention: Students will notice certain things that make each of them unique. They will notice traits including eye color, hair color, earlobes, hair line/shape, tongue rolling, and handedness.
Biology In Elementary Schools is a Saint Michael's College student project. The teaching ideas on this page have been found, refined, and developed by students in a college-level course on the teaching of biology at the elementary level. Unless otherwise noted, th
Ice cream in a Bag!
Developed for first grade. Students will make ice cream from scratch while focusing on the Food Guide Pyramid and what constitutes healthy and unhealthy food choices. Also, in doing this experiment states of matter - solids, liquids, and gases will be covered. While making the ice cream, you can ask the students what they expect to happen. Do they expect the ice cream to turn into a solid? Does it begin as a liquid?

Gerry Wright, director of the Michael G Degroote Institute for Infectious Disease Research at McMaster University, talks about the work performed in his lab and by his colleagues.
In depth: Gerry Wright on antibiotic resistance
Gerry Wright, director of McMaster University's Michael G. DeGroote Institute for Infectious Disease Research, talks about antibiotic resistance, how we can protect against it and what his lab is doing to fight it.
