🔬 Grade 7 Science

Units

1. Unit 1

   🌲Ecosystems

   Biotic and abiotic parts of an ecosystem, how they interact, and the limiting factors and carrying capacity that decide how many organisms an ecosystem can support.

   Curriculum outcome: Interactions with Ecosystems · living and non-living parts of an ecosystem, and what limits populations

2. Unit 2

   🦊Food Chains & Energy

   Producers, consumers and decomposers, food chains and webs, how energy shrinks as it passes up a chain (about 10% each step), and what happens when part of a chain changes.

   Curriculum outcome: Interactions with Ecosystems · producers, consumers, decomposers, food webs and energy flow

3. Unit 3

   ♻️Cycles & Succession

   How water, carbon and nitrogen are cycled through ecosystems, why cycling supports sustainability, and the difference between primary and secondary succession.

   Curriculum outcome: Interactions with Ecosystems · water, carbon and nitrogen cycles, and how land regrows after a change

4. Unit 4

   🐟People & Ecosystems

   How agriculture, harvesting and technologies affect ecosystems, such as monoculture, overfishing, invasive species and runoff, and ways to protect and restore balance. Includes reading simple data about an environmental measure.

   Curriculum outcome: Interactions with Ecosystems · how farming, harvesting and technology affect ecosystems

5. Unit 5

   🌋Restless Earth

   Earth's layers, plate tectonics, earthquakes and volcanoes, fossils in rock layers, and the order of major events in Earth's 4.6-billion-year history. Includes how First Nations oral histories and scientific evidence together date the great 1700 earthquake.

   Curriculum outcome: Earth’s Crust · the layers of Earth, plates, earthquakes, volcanoes and fossils in rock layers

6. Unit 6

   🪨Rocks & Minerals

   Practises how rocks and minerals make up Earth’s crust, how to tell them apart and how rocks change in the rock cycle.

   Curriculum outcome: Earth’s Crust · identifying minerals and rocks, and following the rock cycle

7. Unit 7

   🌊Weathering & Erosion

   Practises how weathering, erosion and deposition wear down and rebuild Earth’s surface, including coastlines and soils.

   Curriculum outcome: Earth’s Crust · how weathering, erosion and deposition shape Earth's surface

8. Unit 8

   🌡️Heat & Particles

   Heat as energy linked to particle motion, temperature, expansion and contraction, changes of state, and the ways heat is generated (friction, electricity, burning, chemical reactions and the Sun).

   Curriculum outcome: Heat · heat, temperature, particle motion, expansion and changes of state

9. Unit 9

   ♨️Moving Heat

   How heat is transmitted by conduction, convection and radiation, how the Sun's radiation heats different surfaces, and technologies such as insulation and double-pane windows that reduce heat loss.

   Curriculum outcome: Heat · conduction, convection and radiation, and technologies that control heat

10. Unit 10

    🥣Particles & Mixtures

    The particle theory of matter, the states of matter, pure substances versus mixtures, and homogeneous versus heterogeneous mixtures.

    Curriculum outcome: Mixtures and Solutions · particle theory, pure substances and kinds of mixtures

11. Unit 11

    🧪Solutions & Separating

    Solutes, solvents and solubility, what makes things dissolve faster, saturated and unsaturated solutions, concentration, why water is called the universal solvent, ways to separate mixtures, and some environmental effects of industrial separation.

    Curriculum outcome: Mixtures and Solutions · solutes, solvents, solubility, concentration and separating mixtures
