Grade 4 Science — Canadian Curriculum Guide
Grade 4 Science explores habitats and communities of living things, investigates the properties of light and sound, examines how pulleys and gears work, and studies rocks, minerals, and erosion. Students deepen their scientific inquiry and experimental design skills.

What Your Child Will Learn in Grade 4 Science
Describe habitats and the relationships between living things in a community
Understand food chains and food webs
Investigate properties of light (reflection, refraction, shadows)
Explore properties of sound (pitch, volume, vibration)
Examine how pulleys and gears change force and motion
Classify rocks and minerals by their properties
Understand erosion and its effects on landforms
Parent Tips for Grade 4 Science
Explore a local pond, forest, or park and identify the habitat — discuss what animals live there and what they eat.
Experiment with flashlights and mirrors at home to explore how light reflects and creates shadows.
Collect rocks on walks and classify them by colour, texture, and hardness to practice mineral identification.
Frequently Asked Questions
What science topics are taught in Grade 4 in Canada?
Grade 4 Science covers habitats and communities, light and sound, pulleys and gears, and rocks, minerals, and erosion, along with scientific investigation skills.
Do Grade 4 students learn about food chains?
Yes. Grade 4 is when students formally study food chains and food webs, understanding how energy flows through ecosystems and the relationships between producers, consumers, and decomposers.
