This math example explains what celestial objects a person can see with the unaided eye from the vantage points of Earth and Mars, using simple math, algebra and astronomical distance information. This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

Carol Ann Patterson discusses the research on canary seed by the Canary Seed Development Commission of Saskatchewan through the Diverse Field Crops Cluster (DFCC).
DFCC is an agri-science cluster led by Ag-West Bio, with funding from Agriculture and Agri-Food Canada’s Canadian Agricultural Partnership program and industry partners.

"The Ministry of Education has provided some questions/considerations for school divisions and schools in preparation of the legalization of three new classes of cannabis on October 17, 2019. The questions and considerations may guide discussions with school boards, school community councils and administrators to review and update policies and administrative procedures. Continue to visit the Cannabis in Saskatchewan website for updates regarding the legalization of cannabis.

Also attached is a sample letter for school divisions and schools that may choose to email/send to families about the upcoming legalization of the three classes of cannabis.

These two resources that look closer at cannabis and how it relates to 1. Pregnancy and 2. Parenting from the Saskatchewan Prevention Institute.

The purpose of this task is to give students practice constructing functions that represent a quantity of interest in a context, and then interpreting features of the function in the light of that context. It can be used as either an assessment or a teaching task.

The primary purpose of this task is to lead students to a numerical and graphical understanding of the behavior of a rational function near a vertical asymptote, in terms of the expression defining the function. The canoe context focuses attention on the variables as numbers, rather than as abstract symbols.

There's been a fair amount of interest in comparing the results of canola seeded with a drill versus a planter over the last decade, but as the percentage of acres sown with planters has increased, farmers and agronomists are also looking to compare different planter setups.

This Canola School episode takes us to a planter demonstration trial near St. Jean-Baptiste, Manitoba, where Brunel Sabourin of Antara Agronomy discusses variations in canola emergence in a series of plots looking at different planter setups and settings.

The purpose of this task is to use finite geometric series to investigate an amazing mathematical object that might inspire students' curiosity. The Cantor Set is an example of a fractal.

Explore the innovative ways countries are revolutionizing farming to ensure we can feed humanity in a way that works with the environment. About 10,000 years ago, humans began to farm. This agricultural revolution was a turning point in our history and enabled the existence of civilization. Today, nearly 40% of our planet is farmland. Spread all over the world, these lands are the pieces to a global puzzle we’re all facing: in the future, how can we feed every member of a growing population a healthy diet? Brent Loken investigates.

Explore how a capacitor works! Change the size of the plates and add a dielectric to see how it affects capacitance. Change the voltage and see charges built up on the plates. Shows the electric field in the capacitor. Measure voltage and electric field.

This short video and interactive assessment activity is designed to teach second graders about capacity comparison problems with illustrations - word problems.

This short video and interactive assessment activity is designed to teach fourth graders about finding the amount of water with illustrations and calculations (metric units).

This short video and interactive assessment activity is designed to teach third graders an overview of capacity IIi (metric units).

This short video and interactive assessment activity is designed to teach second graders about capacity problems with illustrations - word problems.

Students are presented with a short lesson on the difference between cohesive forces (the forces that hold water molecules together and create surface tension) and adhesive forces (the forces that causes water to "stick" to solid surfaces. The interaction between cohesive forces and adhesive forces causes the well-known capillary action. Students are also introduced to examples of capillary action found in nature and in our day-to-day lives.

As part of a (hypothetical) challenge to help a city find the most affordable and environmentally friendly way to clean up an oil spill, students design and conduct controlled experiments to quantify capillary action in sand. Like engineers and entrepreneurs, student teams use affordable materials to design and construct models to measure the rate of capillary action in four types of sand: coarse, medium, fine and mixed. After observing and learning from a teacher-conducted capillary tube demonstration, teams are given a selection of possible materials and a budget to work within as they design their own experimental setups. After the construction of their designs, they take measurements to quantify the rate of capillary action, create graphs to analyze the data, and make concluding recommendations. Groups compare data and discuss as a class the pros and cons of their designs. Pre- and post-evaluations and two worksheets are provided.

In which John Green teaches you about capitalism and socialism in a way that is sure to please commenters from both sides of the debate. Learn how capitalism arose from the industrial revolution, and then gave rise to socialism. Learn about how we got from the British East India Company to iPhones and consumer culture in just a couple of hundred years. Stops along the way include the rise of industrial capitalism, mass production, disgruntled workers, Karl Marx, and the Socialist Beard. The socialist reactions to the ills of capitalism are covered as well, and John discusses some of the ideas of Karl Marx, and how they've been implemented or ignored in various socialist states. Plus, there are robots!
