The Ontario Grade 3 Science and Technology curriculum covers four core science strands plus an overarching STEM skills strand through hands-on inquiry, coding, and real-world connections.

• Life Systems: Growth and Changes in Plants

  • Plant Basics: Learn plant needs (water, air, light, heat, nutrients, space) and plant anatomy (roots, stems, leaves, flowers, seeds).

  • Life Cycles and Adaptations: Explore how plants grow, change, and adapt to their environments.

  • Photosynthesis & Interdependence: Understand how plants turn solar energy into food, and how they connect with animals and humans.

  • Cultural Uses: Examine how plants provide food, shelter, medicine, and clothing, including Indigenous knowledge and local traditions.

• Matter and Energy: Forces and Motion

  • Forces: Investigate contact and non-contact forces (like pushes, pulls, and magnets) and how they change an object's speed or direction.

  • Movement: Design and test devices or rides that use controlled forces to move objects.

• Structures and Mechanisms: Strong and Stable Structures

  • Design & Materials: Study the difference between form and function in structures.

  • Strength and Stability: Build, test, and analyze how shapes, materials, and internal frameworks help structures carry loads and withstand weather or environmental forces.

• Earth and Space Systems: Soils in the Environment

  • Soil Composition: Discover living and non-living parts of soil and different soil types found across Ontario.

  • Erosion and Conservation: Investigate how water and wind cause erosion, and test ways to prevent flooding or soil loss through conservation and composting.

The Grade 3 Ontario Health and Physical Education curriculum covers four key areas to foster healthy habits, physical skills, safety awareness, and emotional resilience.

Social-Emotional Learning (SEL) Skills

• Integrated across all strands, students practice managing emotions, coping with stress, building positive relationships, and applying critical thinking.

Active Living

• Active Participation: Engaging in regular daily physical activity and movement.

• Physical Fitness: Understanding the health benefits of staying active.

• Safety: Following safe play practices, concussion awareness, and injury procedures.

Movement Competence

• Fundamental Movement Skills: Developing stability, locomotion, and object control skills.

• Movement Strategies: Applying spatial awareness, body control, and fair play in group games.

Healthy Living

• Healthy Eating: Exploring nutrition, food sources, oral health, and dietary impacts.

• Personal Safety and Injury Prevention: Learning online safety, safe travel habits, media violence awareness, and concussion signs.

• Substance Use and Addictions: Making informed choices regarding legal/illegal substances and addictive behaviors.

• Human Development and Sexual Health: Understanding healthy relationships, consent, body image, and respecting diversity.

• Mental Health Literacy: Recognizing physical stress signals and identifying emotional triggers.
