Grade 4 — Science

Grade 4 Science covers animal and plant structures that support survival, forms of energy including sound and light, and earth materials including rocks, minerals, and weathering — aligned to the Next Generation Science Standards.

Units & Topics Covered

3 units  ·  18 topics

Life Science: Structures for Survival

  • Internal structures of plants: roots, stems, leaves, seeds
  • Internal structures of animals: skeleton, muscles, organs
  • External structures and how they help organisms survive
  • How senses gather information and the brain processes it
  • Patterns in animal behaviour (migration, hibernation)
  • Plant and animal responses to changes in the environment

Physical Science: Energy

  • Forms of energy: light, heat, sound, electrical, mechanical
  • How sound is produced by vibrations and travels through materials
  • Pitch and volume: how amplitude and frequency affect sound
  • How light travels and interacts with materials (reflection, refraction, absorption)
  • Electrical circuits: conductors and insulators
  • Energy transfer and conversion in everyday objects

Earth & Space Science: Rocks & Natural Hazards

  • Properties and identification of rocks and minerals
  • The three rock types: igneous, sedimentary, and metamorphic
  • Weathering, erosion, and deposition processes
  • The rock cycle and how rocks change over time
  • Renewable vs nonrenewable natural resources
  • Natural hazards: earthquakes, floods, and their impacts
