Vectors: Grade 10
Grade 10: Vectors. Are vectors physics? No, vectors themselves are not physics. Physics is just a description of the world around us. To describe something we need to use a language. The most common language used to describe physics is mathematics. Vectors form a very important part of the mathematical description of physics, so much so that it is absolutely essential to master the use of vectors.

The site is organized in four parts: the atmosphere, hydrosphere (oceans and water), cryosphere (snow and ice), and biosphere (living organisms).
What is Inquiry?
Good science education requires both learning scientific concepts and developing scientific thinking skills. Inquiry is an approach to learning that involves a process of exploring the natural or material world, and that leads to asking questions, making discoveries, and testing those discoveries in the search for new understanding. Inquiry, as it relates to science education, should mirror as closely as possible the enterprise of doing real science.
Definitions of Copyright: What Do They Know?
In this lesson, students will begin to explore the often-perplexing world of copyrights by defining the essential elements of U.S. copyright law. Beginning with the Copy Quiz game and a free-form class discussion, students will tease out collective and individual ideas about the rights of creators and users. Then students will be asked to reflect on their experiences making and using creative works online and write down the questions that they want answered by the end of the unit.

World of Crickets
These four activities, use crickets to teach the scientific process to elementary and middle school students. Students will make observations and record data on the types of food that crickets like to eat. In another lab, students determine if crickets respond to light or dark. A “Crickthermometer” activity asks students to design an experiment to find out whether they can predict air temperature by counting the number of times a cricket chirps. In the last activity, “The Musical World of
Mapping Margery Kempe
Margery Kempe's spiritual biography is often called the first autobiography in English. A married woman who attempted to live a life devoted to Christ, Margery sought official Church recognition for her status as a spiritual woman and mystic, while continuing to live and travel in the secular world. She experienced intense emotional visionary encounters with Christ, which have at times a strikingly homely quality. Her Book, dictated by her to a scribe, records these visions as well as her travel

Chez moi et dans le monde entie
Exploring our use and relationship with water: This unit explores the relationship between people (individuals and populations) and water across the world. The lessons begin at a personal level, inviting students to think about how much water they use and how they could conserve water. The unit broadens to national and international/multicultural issues and perspectives as students compare how much water people use in different parts of the world and contemplate why there is such a wide gap.
Introduction to Stoichiometry
Our on-line Chemistry course covers stoichiometry and demonstrates our scenario based approach to teaching chemistry. Traditional courses tend to follow a bottom-up approach to learning chemistry. This traditional approach teaches abstract concepts and tools before discussing their practical application, which results in students learning bits of unconnected knowledge that are rarely usable let alone memorable. In our approach, scenarios are used both to motivate the material and provide a frame
Empirical Research Methods
Regression analysis is an enormously popular and powerful tool, used ubiquitously in the social and behavioral sciences. Most courses on the subject immediately dive into the mathematical aspects of the subject and illustrate the technique on problems that are already highly structured. As a result, most students come away with little idea of the wide range of problems to which regression analysis can be applied and how to represent those problems in a way that cleverly utilizes readily availabl
What is a Mammal? Answers from Dr. Ross MacPhee (Beyond Penguins and Polar Bears Podcast Extras)
Through a series of short video segments, we interviewed Ross MacPhee, curator in the Department of Mammalogy of the American Museum of Natural History (AMNH) to give us a basic understanding about polar mammals. A paleomammalogist, he travels around the world studying mammals of the ancient past as well as those of today. In particular, MacPhee studies woolly mammoths, the not-so-distant relatives of our present-day elephants.
