Grade 3 Science — Canadian Curriculum Guide
Grade 3 Science dives into plant growth and life cycles, explores forces and how they cause movement, examines what makes structures strong and stable, and investigates soils and the sky. Students develop scientific investigation skills through hands-on experiments.

What Your Child Will Learn in Grade 3 Science
Describe the parts of a plant and their functions
Understand plant life cycles from seed to mature plant
Investigate forces (pushes and pulls) and how they cause movement
Explore what makes structures strong and stable
Examine different types of soil and their properties
Observe patterns in the sky (clouds, sun position, moon phases)
Design and conduct fair tests with controls
Parent Tips for Grade 3 Science
Start a small garden together — even herbs in a windowsill pot let your child observe plant growth and life cycles firsthand.
Build towers and bridges from everyday materials (cardboard, tape, straws) to explore what makes structures stable.
Go outside on clear nights to observe the moon's changing phases — keep a simple moon journal together.
Frequently Asked Questions
What science topics are taught in Grade 3 in Canada?
Grade 3 Science covers plant needs and life cycles, forces and movement, strong and stable structures, soils and the sky, and scientific investigation skills.
Do Grade 3 students learn about forces in Canada?
Yes. Grade 3 is when students formally explore forces (pushes and pulls), friction, gravity basics, and magnetism through hands-on experiments and investigations.
