Overview

So you want to predict the weather? We can do that! You will start by understanding what causes weather in the first place.First, you will learn to use three different theories.You are probably already familiar with the particle theory of matter.We will also use the concept of an air parcel, which is a specialized variation of the particle theory.Finally, we will use these two theories together to develop a third theory of atmospheric pressure.Using pictorial representations of these three theories, you will learn how to calculate atmospheric pressure, energy, temperature, mass and other quantities related to weather. In addition, you will learn how to draw specialized pictures of the earth's atmosphere. You will learn how to use these theoretical descriptions explain and predict the weather around you. Knowledge and understanding will be probed in Daily Quizzes. We will use the PEOE cycle (Predict, Explain, Observe, Explain) for most labs and activities. You will be expected to frame a question, provide your best prediction, and explain your thinking, using both sentences and diagrams. You will use your diagrams to interpret and predict the weather.At the end of the unit, you will be given a five day independent project to demonstrate your ability to conduct your own investigation. The quality of your arguments is the most important aspect of communication in this chapter. Your arguments must consist of sentences, organized into paragraphs, and supported by diagrams or other representations.As in all of the IntuitivScience series, diagrams are an important mode of expression. The diagrams provide the student with tools to analyze the most important forces that influence Earth's weather. Every two-page student exercise uses easy-to-learn diagrams as the building blocks of understanding.Parents and teachers, you get one half of the book! Each two-page student activity is accompanied by a two-page teacher / parent guide, that provides solid pedagogical supports, recipes, and methods of presentation.The book is subdivided into three major sections. Each section will take a little more than one week to complete.Basic structure of the atmosphere and the factors that shape it. Foremost is the particle nature of the gases that make up the atmosphere, and the forces that act upon the gases. Also included is the role of water and its changes of state in the energy economy of the atmosphere.The circulation of air parcels as they absorb and release energy from the sun. This fundamental motion is simple, but can be used to explain complex events like cloud formation, chinooks, and warm and cold fronts.The effect of the spinning of Earth upon the motion of circulating air masses. The winds that we experience are shaped more by the Coriolis effect than by thermal effects. This counter-intuitive idea is one of the more difficult ideas to learn.At the end of the formal exercises, students are invited to undertake a five day structured research project on a weather event of interest to them

Author Information

Jim Ross has more than 34 years experience in science education, both in private and public school systems. For six years he was the Coordinator of Investigative Studies at Nicholson Catholic College, Belleville, ON, where his portfolio included science, math, history, geography, and the social sciences. In 1988, Jim Ross and Mike Lattner founded Ross Lattner Educational Consultants, a small, independent publishing company, to meet the need for high quality curriculum materials in the de-streamed common curriculum. Ross Lattner continues to publish innovative instructional strategies. Jim's M.Ed. thesis, The Graininess of Everyday Thinking, examined the cognitive structure of students' everyday language, and how it is related to students' natural reasoning about physical phenomena. From 2001-2005, Jim taught the pedagogy courses in Chemistry, Physics and Intermediate Science at the Faculty of Education at the University of Western Ontario. In that capacity, he was awarded the honour of Teacher of the Year by the the Faculty of Ed. Jim has served as president of the Ontario Association of Physics Teachers, and has been an active member of STAO. He has contributed to the writing of the Ontario senior physics curriculum documents. Entering an active retirement in 2008, Jim contributed to McGraw-Hill Ryerson's Grade 9 and 10 ON Science texts. As he continues to study and write, he has been constructing the new approach to chemistry learning and teaching with Edvantage Press, and is an active member of the Edvantage Chemistry Interactive online community.
