The "Habitats and Communities" unit in the Ontario Grade 4 Science curriculum explores the relationships between living organisms and their environments. This unit covers the concepts of habitats, ecosystems, food chains, and the impact of human activities on natural communities. Below are the main subsections, along with recommended educational videos that align with these topics:
1. Understanding Habitats
Main Ideas:
Define what a habitat is and identify the different types of habitats (e.g., forests, deserts, wetlands, oceans).
