Bilingual Ontario Multimedia Curriculum Resources for Science & Technology Teachers

Teachers, Our Incredible World (www.incredibleworld.ca)  offers multimedia curriculum resources for the Science & Technology strand suitable for grades 4 to 11. All video series, lesson plans, games, newsletters/factsheets, career profiles, and other resources are designed with teachers, for teachers. They cover topics such as: habitats, ecosystems, biodiversity, species-at-risk, invasive species, and other related life sciences subjects. All videos can be viewed on the site.

Filmed in Ontario, each video series features 2 young people -Incredible World Investigators on assignment to interview scientists and discover firsthand why some species are at risk and what is being done about it. From tracking wolves in the boreal forest in the dead of winter, to converting a suburban lawn into a shared habitat for a multitude of species, including bats, the young investigators have fun, while taking their assignments seriously.

Each series is accompanied by lessons that tie the video story-line to the Ontario’s Science and Technology curriculum. The lessons provide a stimulating mix of science-based class discussions and activities and allow educators to integrate group work, skills-building exercises, research, experiments, art, graphing, data recording, critical thinking, and debating into their classrooms. They culminate with students creating a variety of assessment products including informational posters, graphic organizers, and project assessment reports.
