🔬 Grade 7 Science

Units

1. Unit 1

   🌱Tundra Ecosystems

   Covers tundra conditions, permafrost, food chains and a changing Arctic. The Nunavut adaptation of the Alberta Science 7–9 program encourages learning with Elders and from the land alongside the classroom.

   Approved guide: Nunavut adaptation of Alberta Science 7–9 (2003), Unit A: Interactions and Ecosystems · tundra ecosystems, permafrost and food chains

2. Unit 2

   🌲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.

   Approved guide: Nunavut adaptation of Alberta Science 7–9 (2003), Unit A: Interactions and Ecosystems · ecosystems, living and non-living parts and limiting factors

3. Unit 3

   🦊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.

   Approved guide: Nunavut adaptation of Alberta Science 7–9 (2003), Unit A: Interactions and Ecosystems · producers, consumers, decomposers and energy transfer

4. Unit 4

   ♻️Cycles & Succession

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

   Approved guide: Nunavut adaptation of Alberta Science 7–9 (2003), Unit A: Interactions and Ecosystems · cycles of matter and how ecosystems change over time

5. Unit 5

   🐟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.

   Approved guide: Nunavut adaptation of Alberta Science 7–9 (2003), Unit A: Interactions and Ecosystems · how people and their technologies affect ecosystems

6. Unit 6

   🌱How Plants Work

   The parts of seed plants and what they do, photosynthesis, gas exchange, transpiration and pollination, and how plant structures suit where a plant grows.

   Approved guide: Nunavut adaptation of Alberta Science 7–9 (2003), Unit B: Plants for Food and Fibre · the structure and life processes of seed plants and how they suit their environment

7. Unit 7

   🚜Growing Crops Well

   Fertilizers and soil nutrients, selective breeding, crop rotation, chemical and biological pest control and farming practices that protect soil and water.

   Approved guide: Nunavut adaptation of Alberta Science 7–9 (2003), Unit B: Plants for Food and Fibre · soil nutrients, plant breeding, pest control and sustainable growing methods

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).

   Approved guide: Nunavut adaptation of Alberta Science 7–9 (2003), Unit C: Heat and Temperature · heat, temperature and the particle model

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.

   Approved guide: Nunavut adaptation of Alberta Science 7–9 (2003), Unit C: Heat and Temperature · conduction, convection, radiation and controlling heat transfer

10. Unit 10

    🌉Structures & Forces

    Solid, frame and shell structures, centre of gravity and stability, symmetry, and the size, direction and point of application of forces, including tension, compression, torsion and shear.

    Approved guide: Nunavut adaptation of Alberta Science 7–9 (2003), Unit D: Structures and Forces · kinds of structures, forces and how structures stay stable
