This task requires students to think of dimes and pennies as fractions of dollars.

This task does not actually require that the student solve the system but that they recognize the pairs of linear equations in two variables that would be used to solve the system. This is an important step in the process of solving systems.

Les sujets de Français (lecture et écriture) et études sociales (communauté et environnement) seront étudiés dans cette leçon.

Students create model elevator carriages and calibrate them, similar to the work of design and quality control engineers. Students use measurements from rotary encoders to recreate the task of calibrating elevators for a high-rise building. They translate the rotations from an encoder to correspond to the heights of different floors in a hypothetical multi-story building. Students also determine the accuracy of their model elevators in getting passengers to their correct destinations.

The purpose of this task is to illustrate through an absurd example the fact that in real life quantities are reported to a certain level of accuracy, and it does not make sense to treat them as having greater accuracy.

Through discussion and hands-on experimentation, students learn about the geological (ancient) carbon cycle. They investigate the role of dinosaurs in the carbon cycle and the eventual storage of carbon in the form of chalk. Students discover how the carbon cycle has been occurring for millions of years and is necessary for life on Earth. Finally, they may extend their knowledge to the concept of global warming and how engineers are working to understand the carbon cycle and reduce harmful CO2 emissions.

Let's continue the exploration of the Water Cycle by drinking some dinosaur pee. Yep! Well, it's a little less gross that it sounds. It turns out that all of the water on Earth is just constantly recycled in what we call a closed system. No water comes in and no water goes out. So that means that, at some point, it's possible the water we're drinking was once dinosaur pee... or tears...

This informational text introduces students to the dinosaurs found near the polar regions and discusses the adaptations that allowed these dinosaurs to survive in a dark and cold environment. The text is written at a kindergarten through grade one reading level. This is a PDF containing the informational text and a glossary.

This informational text introduces students to the dinosaurs found near the polar regions and discusses the adaptations that allowed these dinosaurs to survive in a dark and cold environment. The text is written at a kindergarten through grade one reading level. This version is a full-color PDF that can be printed, cut and folded to form a book. Each book contains color photographs and illustrations.

What's that sound? Students participate in a Directed Listening-Thinking Activity (DLTA) using "The Tell-Tale Heart," make predictions, and respond in the form of an acrostic poem or comic strip.

We know about food chains and how energy moves through an ecosystem. This video takes a step back to examine everything starts... and ends - with Decomposers!

Students design and conduct experiments to determine what environmental factors favor decomposition by soil microbes. They use chunks of carrots for the materials to be decomposed, and their experiments are carried out in plastic bags filled with dirt. Every few days students remove the carrots from the dirt and weigh them. Depending on the experimental conditions, after a few weeks most of the carrots will have decomposed completely.

This map shows the distribution of the top 12 items picked up on Canadian shorelines across the country in 2017. A shoreline is anything that is connected to water: which includes coastlines, lake shores, river shores, inland communities, and storm drains. Marine debris is coming from all across the country. Do you use any of these items? What actions can you take to reduce the impact? Find out more.

In this activity, students investigate different methods (aeration and filtering) for removing pollutants from water. They will design and build their own water filters.

Students disassemble and analyze retractable pens. Through the process of "reverse engineering," they learn how the ink pens work.

This purpose of this task is to help students see two different ways to look at percentages both as a decrease and an increase of an original amount. In addition, students have to turn a verbal description of several operations into mathematical symbols.
