This task provides a real world context for interpreting and solving exponential equations. There are two solutions provided for part (a). The first solution demonstrates how to deduce the conclusion by thinking in terms of the functions and their rates of change. The second approach illustrates a rigorous algebraic demonstration that the two populations can never be equal.

Students construct paper recombinant plasmids to simulate the methods genetic engineers use to create modified bacteria. They learn what role enzymes, DNA and genes play in the modification of organisms. For the particular model they work on, they isolate a mammal insulin gene and combine it with a bacteria's gene sequence (plasmid DNA) for production of the protein insulin.

True love has the right ratio. In this humorous animation, the number of words spoken by each partner predicts whether a date goes well or horribly. What do you do when someone asks if you listen to country music backwards, but won't let you get a word in edgewise?

Bagages (ONF)

Rating
0.0 stars

Bagages est un film qui donne la parole et la scène à des adolescents de l’école secondaire Paul-Gérin-Lajoie-d’Outremont nouvellement arrivés à Montréal. On découvre leur récit de migration et d’intégration à travers des ateliers d’art dramatique, des mises en scènes théâtrales et des entrevues où ils se révèlent à nous. Ils témoignent d’un « ailleurs » et d’un « avant » qui deviendront « ici » et « maintenant ». Ils sont jeunes, mais parlent de leur parcours avec une sagesse déconcertante, une émotion à faire trembler les plus durs et une authenticité désarmante.

**Il existe une mini-leçon pour le film Bagages. Le lien est trouvé sur ce site.

The Baker's Neighbor
Read the Fine Print
Rating
0.0 stars

This lesson provides teachers with support for using text-dependent questions to help students derive big ideas and key understandings while developing vocabulary from the modern fable and play, The Baker's Neighbor. In this play, the neighborhood baker Manuel bakes delicious smelling pastries and puts them out for sale each morning, but his neighbor, Pablo, loves to smell the fresh bakery every morning without purchasing any pastries. This irritates Manuel to the point where he feels Pable should pay to smell his baked goods, and Manuel takes his complain to the town judge who eventually offers a ruling that allows Manuel to get the pleasure of "touching" Pablo's gold coins in return for Pable "smelling" the bakery.

The Balancing Act
Read the Fine Print
Educational Use
Rating
0.0 stars

Students visualize and interact with concepts already learned, specifically algebraic equations and solving for unknown variables. They construct a balancing seesaw system (LEGO® Balance Scale) made from LEGO MINDSTORMS® parts and digital components to mimic a balancing scale. They are given example algebraic equation problems to analyze, configure onto the balance scale, and evaluate by manipulating LEGO pieces and gram masses that represent terms of an equation such as unknown variables, coefficients and integers. Digital light sensors, built into the LEGO Balance Scale, detect any balance or imbalances displayed on the balancing scale. The LEGO Balance Scale interactively issues a digital indication of balance or imbalance within the system. If unbalanced, students continue using the LEGO Balance Scale until they are confident in their understanding of solving algebraic equations. The goal is for students to become confident in solving algebraic equations by fundamentally understanding the basics of algebra and real-world algebraic applications.

‪Ballons et Electricité statique‬-(Simulation PhET)
Unrestricted Use
CC BY
Rating
0.0 stars

Une série de simulations provenant de l’Université de Colorado à Boulder pour les 9e – 12e au sujet des sciences. Cette simulation démontre le processus de ballons et electricité statique.

Les élèves explorent l'électricité statique en frottant un ballon simulé sur un pull. En observant les charges dans le pull, le ballon et le mur adjacent, ils acquièrent une compréhension du transfert de charge. Cet élément fait partie d'une collection plus vaste de simulations développées par le projet de technologie éducative en physique (PhET). Les simulations sont des environnements animés, interactifs et ludiques.
