In a multi-week experiment, student groups gather data from the photobioreactors that they build to investigate growth conditions that make algae thrive best. Using plastic soda bottles, pond water and fish tank aerators, they vary the amount of carbon dioxide (or nutrients or sunlight, as an extension) available to the microalgae. They compare growth in aerated vs. non-aerated conditions. They measure growth by comparing the color of their algae cultures in the bottles to a color indicator scale. Then they graph and analyze the collected data to see which had the fastest growth. Students learn how plants biorecycle carbon dioxide into organic carbon (part of the carbon cycle) and how engineers apply their understanding of this process to maximize biofuel production.

Water travels... a lot. In fact, the water cycle is amazing and takes water all over the planet by using evaporation, condensation, and precipitation. In this episode of Crash Course Kids, Sabrina shows us how the water cycle works and how you can create a mini water cycle right in your own kitchen!

This collection of images was part of the first group of 360 images added to Google Maps. You can explore more 360 views through the Google Maps Street View collection.

Jump on the Great Canadian Farm Tour! Throughout the month of March, AITC-C is hosting 11 different farm tours focusing on the diversity of commodities across Canada.

Stopping in each province to co-host with our provincial member organizations, your students will LEARN about Canada’s exciting agriculture and food story, CONNECT and interact virtually with real farmers, and EXPERIENCE what it’s like on farms across the country.

This extraordinary learning opportunity will inspire your students, ignite their curiosity, and teach them about the important role agriculture plays in their lives, EVERY DAY!

Learn more about the Great Canadian Shoreline Cleanup, including information on the sources and impacts of shoreline litter and what our national network of volunteers are doing to make a positive difference! Explore interactive maps that contain data from cleanups across Canada in 2017 and discover the most common items found on shorelines. We also provide ideas for how you can get involved by reducing your use and leading a shoreline cleanup in your community!

Ted Talk: On March 15th, 44 BCE, Roman dictator Julius Caesar was assassinated by a group of about 60 of his own senators. Why did these self-titled Liberators want him dead? And why did Brutus, whose own life had been saved by Caesar, join in the plot? Kathryn Tempest investigates the personal and political assassination of Julius Caesar.

In this activity, students will use cookies to simulate the distribution of our nonrenewable resources (energy). Then, they will discuss how the world's growing population affects the fairness and effectiveness of this distribution of these resources and how engineers work to develop technologies to support the population.

Do you know how many people have been to the moon? Only 12! Part of the reason it's so few is because of how difficult it is to escape Earth and get into space in the first place. In this episode of Crash Course Kids, Sabrina talks about gravity, escape velocity, and how gravity works between two objects.

Hank fills us in on the endocrine system - the system of glands which produce and secrete different types of hormones directly into the bloodstream to regulate the body's growth, metabolism, and sexual development & function.

Students use water balloons and a length of string to understand how the force of gravity between two objects and the velocity of a spacecraft can balance to form an orbit. They see that when the velocity becomes too great for gravity to hold the spacecraft in orbit, the object escapes the orbit and travels further away from the planet.

Great Lakes Now brings along students on a virtual field trip to learn more about the importance of coastal wetlands, the danger of algal blooms and a deep dive into lake sturgeon.

This experience is targeted for 6-8th grade, but is certainly not limited to this age group.

This is a website that serves as an online textbook to tell the story of William Gilbert, English physicist during the time of Queen Elizabeth I, and the history of the discovery of Earth's magnetism. Learners can read about historical studies of magnetism, connections between sunspot activity and the Earth's magnetic field, the internal dynamo responsible for generating the Earth's magnetic field, magnetic polarity and reversals, and geomagnetic storms.

Like Earth, Mars has valleys that seem to be caused by a flowing fluid, presumably water. One can see dendritic drainage patterns as well as flood channels on the Martian surface. This module focuses on whether the channels observed on Mars are evidence of great floods and, if so, on how Pathfinder helps scientists to use the debris from such floods to obtain information about four billion years of Martian geologic history.

The Great Pacific Garbage Patch (GPGP) is an intriguing and publicized environmental problem. This swirling soup of trash up to 10 meters deep and just below the water surface is composed mainly of non-degradable plastics. These plastic materials trap aquatic life and poison them by physical blockage or as carriers of toxic pollutants. The problem relates to materials science and the advent of plastics in modern life, an example of the unintended consequences of technology. Through exploring this complex issue, students gain insight into aspects of chemistry, oceanography, fluids, environmental science, life science and even international policy. As part of the GIS unit, the topic is a source of content for students to create interesting maps communicating something that they will likely begin to care about as they learn more.

In this episode of Crash Course Kids, Sabrina talks about all the different mixtures, solutions, and ants that can be at a picnic.

The Great War Video Series
Key Canadian battles during the First World War led to the march to victory in 1918.

Created by Canada’s History — October 1, 2018
When the First World War began in 1914, Canada had no choice — as part of the British Empire, the country was automatically at war.

More than 650,000 Canadians served over the course of the four-year conflict, an impressive number for a population of around eight million. And, through its successes on the battlefield, Canada proved itself many times. But the fighting took its toll; by the end of the war, more than 66,000 Canadians had been killed, and another 172,000 had been wounded.

November 11, 2018, marks the hundredth anniversary of the end of the First World War. Here are just a few key Canadian battles along the road to armistice in 1918.

This educator resource provides videos, book suggestions, toolkits and other resources for character education.

This short video and interactive assessment activity is designed to teach fourth graders about greater or less than comparisons of length (english units).
