The purpose of this video lesson is to expand the student's knowledge about enzymes by introducing the antioxidant enzymes that are intimately involved in the prevention of cellular damage and eventual slowing of the aging process and prevention of several diseases. Students will learn that natural antioxidant enzymes are manufactured in the body and provide an important defense against free radicals. The topic of free radical action is introduced, covering how they are constantly generated in living cells both by ''accidents of chemistry'' and also by specific metabolic processes.

Grâce à une analyse multidisciplinaire et décomplexée de notre relation à l’intelligence artificielle (I.A.), nous questionnerons nos usages quotidiens de l’I.A. Nous remonterons à l’origine historique de la notion d’« intelligence artificielle » afin d’en tirer des questions pratiques et des réponses concrètes, ainsi que des pistes de réflexion. Ensuite, nous aborderons les principes de base du fonctionnement de l’I.A. moderne pour y puiser une série de clés de compréhension. Enfin, nous nous arrêterons sur les craintes et idées reçues qui cernent le débat actuel autour de l’I.A. pour alors débattre collectivement de questions résolument actuelles.

The main objective of this lesson is to illustrate an important application of mathematics in practical life -- namely in art. Most of the pictures selected for this lesson are visible on the walls of Al-Hambra – Granada (Spain), which is one of the most important landmarks in the Islamic civilization. There are three educational goals for this lesson: (1) establishing the concept of isometries; (2) giving real-life examples of groups; (3) demonstrating the importance of matrices and their applications. As background for this lesson, students just need some familiarity with the concept of a group and a limited knowledge about matrices and the inverse of a non-singular matrix.

This short video and interactive assessment activity is designed to teach third graders about creating largest and smallest numbers given digits.

This learning video deals with a question of geometrical probability. A key idea presented is the fact that a linear equation in three dimensions produces a plane. The video focuses on random triangles that are defined by their three respective angles. These angles are chosen randomly subject to a constraint that they must sum to 180 degrees. An example of the types of in-class activities for between segments of the video is: Ask six students for numbers and make those numbers the coordinates x,y of three points. Then have the class try to figure out how to decide if the triangle with those corners is acute or obtuse.
