In this unit we revisit the model developed in the first unit of this series on pollution in the Great Lakes of North America. Here we evaluate and revise the original model by comparing its predictions against data from the lakes before finally reflecting on the techniques used. This unit, the fifth in a series of five, builds on ideas developed and introduced in Modelling pollution in the Great Lakes Studying mammals: The opportunists Studying mammals: Return to the water Neighbourhood nature Introducing the environment: Ecology and ecosystems School activities: Evolutionary tree of mammals Revolutions in sound recording Identity and Access Control Today I woke up thinking that talking about Identity and Access Control and how your strategy around that affects you (web-) app's architecture without going too deeply into the security lingo that usually comes with it.

Many mammals are food specialists, with complex adaptations that gear them toward a particular food source. So how do the omnivores survive and prosper without these fancy evolutionary features? This free course, Studying mammals: The opportunists, examines the physiology, diet and strategies of some of these opportunistic feeders. It is the sixth course in the Studying mammals series.Author(s):
Some of the most unusual and versatile of all the mammals are the groups that live, feed and reproduce underwater. In this free course, Studying mammals: Return to the water, we will see how these formerly land-based mammals adapted to a return to the water, discussing such challenges as breathing, movement and communication. This is the seventh course in the Studying mammals series.Author(s):
There is a fascinating world of nature all around us which we can see if we know how to look for it. Wherever you live, be it in a city or the countryside, you will find areas that support a range of wildlife. This free course, Neighbourhood nature, will provide you with basic scientific and observational skills so that you can go into your local neighbourhood to discover the animals and plants in open spaces. You will learn how to observe, identify and record the wildlife around you, building u
What is ecology and why is it important to our understanding of the world around us? This free course, Introducing the environment: Ecology and ecosystems, looks at how we can study ecosystems to explore the effect that humans are having on the environment.

This introduction to the evolution of mammals considers Darwin's observations on mammals and how he noticed that species fell into natural groups. This free course, School activities: Evolutionary tree of mammals, looks at evidence from fossils and DNA to examine which mammals are most closely related to whales.

Since the invention of the phonograph in 1877, the recording and playback of sound has been a key element of life in the western world. This free course, Revolutions in sound recording, traces the technology and characters of the sound recording industry as it advances from Edison's original phonograph to the formats we know today.

Isaac Newton was born December 25, 1642 in Woolsthorpe, Lincolnshire, England, and died March 20, 1727 in London, England. Newton was an English physicist and mathematician, who was also the culminating, figure of the scientific revolution of the 17th century. With discoveries in optics, motion, and mathematics he developed the principles of modern physics. He was the original discoverer of the infinitesimal calculus. Newton's Philosophiae Naturalis Principia Mathematica (Mathematical Principles
