An interactive applet and associated web page that demonstrate the concept of concentricity. The applet shows two resizeable concentric circles and the common center point. As they are dragged to resize, they remain concentric. Applet can be enlarged to full screen size for use with a classroom projector.

Concepts of Biology is designed for the introductory biology course for nonmajors taught at most two- and four-year colleges. The scope, sequence, and level of the program are designed to match typical course syllabi in the market. Concepts of Biology includes interesting applications, features a rich art program, and conveys the major themes of biology.

This site provides lessons developed to help students understand the Inuit culture.
Lesson 1
- Lesson Question: How do Inuit on Baffin Island live, and how does Arctic life resemble and differ from ours?
Lesson 2
- Lesson Question: What can Inuit life on Baffin Island teach us?
Lesson 3-4
- Lesson Question: How does a short book about the Arctic (such as Michael Arvaarluk Kusugak's NORTHERN LIGHTS: THE SOCCER TRAILS or his BASEBALL BATS FOR CHRISTMAS, both from Annick Press, Buffalo, NY) illustrate Inuit life, social interaction, and environments?
Lesson 5
- Lesson Question: How does Inuit culture reflect beliefs, issues, and events relevant to societies past and present?
Lesson 6
- Lesson Question: How does Inuit culture compare to my own culture?

For a semester-length course, all seven chapters can be covered. For a shorter course, the book is designed so that chapters 1, 2, and 5 are the only ones that are required for continuity; any of the others can be included or omitted at the instructor’s discretion, with the only constraint being that chapter 6 requires chapter 4.

Concours d’art oratoire is an annual public speaking event across Canada for students studying French. It began in the Ottawa-Carlton area in 1975 and has expanded across the country. The program within the province is sponsored by Canadian Parents for French – Saskatchewan.

In Saskatchewan, students participate in Concours d’art oratoire in categories according to their grade level, current French program and past experience using French.

The objective of Concours d’art oratoire is to stimulate the interest of students in the
learning of French. Concours d’art oratoire is an excellent way to improve oral French
expression. It encourages students to use French in a meaningful way, which
increases their self-esteem, confidence, and ability to communicate. Speech
preparation can be integrated into the curriculum. Students are recognized for their
efforts locally, at the provincial competition, and for those students in grades 11/12
at a national event.

This lesson combines conditional probability and combinations to determine the probability of picking a fair coin given that it flipped 4 out of 6 heads. [Probability playlist: Lesson 16 of 29]

With the help of simple, teacher-led demonstration activities, students learn the basic concepts of heat transfer by means of conduction, convection, and radiation. Students then apply these concepts as they work in teams to solve two problems. One problem requires that they maintain the warm temperature of one soda can filled with water at approximately body temperature, and the other problem is to cause an identical soda can of warm water to cool as much as possible during the same thirty-minute time interval. Students design their solutions using only common, everyday materials. They record the water temperatures in their two soda cans every five minutes, and prepare line graphs in order to visually compare their results to the temperature of an unaltered control can of water.

Experiment with conductivity in metals, plastics and photoconductors. See why metals conduct and plastics don't, and why some materials conduct only when you shine a flashlight on them.

Students make a simple conductivity tester using a battery and light bulb. They learn the difference between conductors and insulators of electrical energy as they test a variety of materials for their ability to conduct electricity.

Incorporating elders’ wisdom in the process of systematically analyzing climate impacts and vulnerabilities in nine categories of tribal life prioritizes actions to take to enhance the evolution of an ancient culture, while protecting tribal traditions.

Today we’re going to talk about confidence intervals. Confidence intervals allow us to quantify our uncertainty, by allowing us to define a range of values for our predictions and assigning a likelihood that something falls within that range. And confidence intervals come up a lot like when you get delivery windows for packages, during elections when pollsters cite margin of errors, and we use them instinctively in everyday decisions. But confidence intervals also demonstrate the tradeoff of accuracy for precision - the greater our confidence, usually the less useful our range.

In which John Green teaches you about conflict in Israel and Palestine. This conflict is often cast as a long-term beef going back thousands of years, and rooted in a clash between religions. Well, that's not quite true. What is true is that the conflict is immensely complicated, and just about everyone in the world has an opinion about it. John is going to try to get the facts across in under 13 minutes.

Each winter, massive waves attract surfers and visitors to the North Shore of O‘ahu in Hawai‘i. Some years, the waves cause severe erosion, and continuing sea level rise will accelerate this issue. Residents and the state are taking steps to preserve homes and beaches.

An interactive applet and associated web page that demonstrate the concept of congruent angles. Three angles are shown which always remain congruent as you drag any defining point on any angle. They all change together. This is designed to demonstrate that the angles are considered congruent even if they are in different orientations and the line segments making them up are different lengths. Applet can be enlarged to full screen size for use with a classroom projector.

An interactive applet and associated web page that demonstrate congruent line segments (segments that are the same length). The applet shows three line segments that are the same length. They all have draggable endpoints. As you drag any endpoint the other lines change to remain congruent with the one you are changing. Applet can be enlarged to full screen size for use with a classroom projector.

An interactive applet and associated web page that demonstrate the congruence of polygons. The applet presents nine polygons that are in fact congruent, but don't look it because they are reflected and rotated in various ways. If you click on one, it rotates and flips as needed, then slides over the top of another to show it is congruent. The web page describes how to determine if two polygons are congruent. Applet can be enlarged to full screen size for use with a classroom projector.

This task is designed to give students insight into the effects of translations, rotations, and reflections on geometric figures in the context of showing that two figures are congruent.

Students' first experience with transformations is likely to be with specific shapes like triangles, quadrilaterals, circles, and figures with symmetry. Exhibiting a sequence of transformations that shows that two generic line segments of the same length are congruent is a good way for students to begin thinking about transformations in greater generality.
