Grade 4 Science
6 units matched to the BC Curriculum.
Big Ideas
- All living things sense and respond to their environment.
- Matter has mass, takes up space, and can change phase.
- Energy can be transformed.
- The motions of Earth and the moon cause observable patterns that affect living and non-living systems.
Units
Unit 1
Sense & Respond
How people, animals and plants sense and respond to their environment: the nervous system, reflexes, special animal senses and plant responses to light, gravity and touch.
Learning standard: Sensing and responding: humans, other animals and plants
Unit 2
Biomes
Earth's major biomes (tundra, boreal forest, grassland, desert, rainforest and more), reading clue tables and rainfall graphs, and how living things are adapted to each biome.
Learning standard: Biomes as large regions with similar environmental features
Unit 3
Phase Changes
The six changes of state, whether heat is added or taken away, and everyday examples like dew, frost and drying puddles.
Learning standard: Phase changes: melting, freezing, evaporation, condensation, sublimation and deposition
Unit 4
Particles & Mass
Solids, liquids and gases at the particle level, how temperature changes particle speed, and conservation of mass (melting or dissolving doesn't change the total mass), with some adding of grams.
Learning standard: Matter has mass and takes up space; effect of temperature on particle movement; conservation of mass
Unit 5
Energy Changes
Forms of energy, how everyday devices change one form into another, renewable and non-renewable resources, and how hydroelectricity is made.
Learning standard: Energy has various forms and can be transformed; devices that transform energy; local energy resources
Unit 6
Earth, Moon & Sun
How Earth's spin causes day and night, how its tilt and orbit cause seasons, the moon's phases, tides and eclipses, and how these patterns affect plants and animals.
Learning standard: Earth's rotation and revolution (day and night, seasons); phases of the moon; tides; eclipses
