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.»
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 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.
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?
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.
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 Oahu in Hawaii. 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.
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.
