Locks and Dams
Students are introduced to the structure, function and purpose of locks and dams, which involves an introduction to Pascal’s law, water pressure and gravity.
Are Dams Forever?
Students learn that dams do not last forever. Similar to other human-made structures, such as roads and bridges, dams require regular maintenance and have a finite lifespan. Many dams built during the 1930-70s, an era of intensive dam construction, have an expected life of 50-100 years. Due to inadequate maintenance and/or for environmental reasons, some of these dams will fail or be removed in the next 50 years. The engineers with Splash Engineering have an ethical obligation to remind Thirsty
Visible Light and the Electromagnetic Spectrum
In this lesson, the electromagnetic spectrum is explained and students learn that visible light makes up only a portion of this wide spectrum. Students also learn that engineers use electromagnetic waves for many different applications.
Permeable Pavement
Students investigate how different riparian ground covers, such as grass or pavement, affect river flooding. They learn about permeable and impermeable materials through the measurement how much water is absorbed by several different household materials in a model river. Students use what they learn to make recommendations for engineers developing permeable pavement. Also, they consider several different limitations for design in the context of a small community.
Energy Power Foods
Feeling low on energy? Maybe it's because you haven't eaten in awhile! Did you know that your food is an example of stored energy? It's chemical potential energy to be exact! And some foods have more energy power than others. This brief news clip gives you tips on how to fight fatigue and the midday blahs by providing several examples of energy power foods. (03:12)
2.3.1 Introduction
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.

DNA Evidence Training
These training modules are intended to provide interactive training that covers basic information about the identification, preservation, and collection of DNA evidence at virtual crime scenes related homicide, sexual assault, and burglary. Information addressed in this interactive training program is delivered in two modules.
The Beginning Level Module focuses on issues that arise for the first-responding law enforcement officer.
The Advanced Level Module delivers more in-depth information for
2.2 The semiotic approach to textual meaning: image and ideology Think of an image of a celebrity winning an award. How is s/he photographed, dressed and accompanied? Perhaps the most likely image you thought of was a full-length or mid-shot of the celebr

Progression of Hurricane Jeanne, 2004 (WMS)
Hurricane Jeanne was the fourth hurricane to hit Florida during the 2004 hurricane season. This set of images shows the progression of the hurricane as it approached Florida from the Atlantic Ocean and the Caribbean Sea. When it hit the Florida coast on September 26, Jeanne was a Category 3 storm with sustained winds near 115 miles per hour.

Newton Gets Me Moving
In this lesson, students will explore motion, rockets and rocket motion while assisting Spacewoman Tess, Spaceman Rohan and Maya in their explorations. They will first learn some basic facts about vehicles, rockets and why we use them. Then, the students will discover that the motion of all objects including the flight of a rocket and movement of a canoe is governed by Newton's three laws of motion.
Life in the City
This fun Web site is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they take a close-up look at biodiversity in a city park. The site opens by telling kids that, despite appearances, a great deal of biodiversity exists in cities. That from tiny mites to mighty trees, thousands of species thrive there. It then takes them to a slice of life from a thriving city park, where they are asked to find 10 hidden critters living alongside the trees, plant
Improved transport shipment of different varieties of bananas
A report on the study done to (1) identify the existing handling practices in the transport shipment of bananas using the modified non-refrigerated vans, (2) determine the profitability of the existing and improved practices in banana transport, (3) reduce losses in mixed varieties of banana through development of local and export-oriented postharvest technology packages, (4) create awareness of the basic concepts of handling, packaging, storage and transport of bananas and; (5) develop product
