Today we’re going to talk about how computers see. We’ve long known that our digital cameras and smartphones can take incredibly detailed images, but taking pictures is not quite the same thing. For the past half-century, computer scientists have been working to help our computing devices understand the imagery they capture, leading to advancements everywhere, from tracking hands and whole bodies, biometrics to unlock our phones, and eventually giving autonomous cars the ability to understand their surroundings.

The purpose of this series of tasks is to build in a natural way from accessible, concrete problems involving volume to a more abstract understanding of volume. The purpose of this first task is to see the relationship between the side-lengths of a cube and its volume.

The purpose of this series of tasks is to build in a natural way from accessible, concrete problems involving volume to a more abstract understanding of volume. In this iteration, we do away with the lines that delineate individual unit cubes (which makes it more abstract) and generalize from cubes to rectangular prisms.

The purpose of this series of tasks is to build in a natural way from accessible, concrete problems involving volume to a more abstract understanding of volume. Here, we are given the volume and are asked to find the height.

The purpose of this series of tasks is to build in a natural way from accessible, concrete problems involving volume to a more abstract understanding of volume. This problem is based on ArchimedesŐ Principle that the volume of an immersed object is equivalent to the volume of the displaced water.

«Les Compétences pour réussir, anciennement appelées compétences essentielles, ont été identifiées et lancées par le gouvernement du Canada en mai 2021, mettant à jour le cadre existant en réponse à un marché du travail en évolution. Ces 9 compétences sont mises à jour pour refléter l'évolution rapide des besoins et des exigences en matière de compétences:

-Calcul
-Communication
-Collaboration
-Résolution de problèmes
-Rédaction
-Adaptabilité
-Lecture
-Créativité et innovation
-Compétences numériques

Elles constituent la base de l'apprentissage de toutes les autres compétences et permettent aux gens d'évoluer dans leur travail et leur vie et de s'adapter aux changements sur le lieu de travail et dans la vie.

Vous trouverez ci-dessous de plus amples informations sur ces compétences, ainsi que des cahiers d'exercices, des évaluations, des livrets et bien plus encore ! Ces outils sont conçus pour que les élèves et les enseignants les utilisent dans leurs cours.»

An interactive applet and associated web page that demonstrate the concept of a concave polygon - one where at least one interior angle is greater than 180 degrees. The applet shows an irregular polygon initially with one interior angle greater than 180 degrees. The user can drag any vertex and change the number of sides in the range 3..99. When the polygon is concave, the angles that make it so are drawn in red. The goal is to show through experimentation what the concept of concavity really means. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.

Students investigate the property dependence between concentrations and boiling point. In section 1, students first investigate the boiling point of various liquid solutions. In section 2, they analyze data collected by the entire class to generate two boiling point curves, one for salt solutions and one for sugar solutions. Finally, in section 3, students use the data they have analyzed to determine how to create a solution that has a particular boiling point and is a cost-effective design.

Students learn how the total solar irradiance hitting a photovoltaic (PV) panel can be increased through the use of a concentrating device, such as a reflector or lens. This is the final lesson in the Photovoltaic Efficiency unit and is intended to accompany a fun design project (see the associated Concentrating on the Sun with PVs activity) to wrap up the unit. However, it can be completed independently of the other unit lessons and activities.

Students design, build and test reflectors to measure the effect of solar reflectance on the efficiency of solar PV panels. They use a small PV panel, a multimeter, cardboard and foil to build and test their reflectors in preparation for a class competition. Then they graph and discuss their results with the class. Complete this activity as part of the Photovoltaic Efficiency unit and in conjunction with the Concentrated Solar Power lesson.

Watch your solution change color as you mix chemicals with water. Then check molarity with the concentration meter. What are all the ways you can change the concentration of your solution? Switch solutes to compare different chemicals and find out how concentrated you can go before you hit saturation!

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.

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.
