- Learning with Elders and from the land is encouraged alongside classroom science.
Units
Unit 1
Biodiversity & Heredity
Why variety within and between species helps living things survive, how symbiosis works, sexual and asexual reproduction, the basics of DNA, genes and chromosomes, and how people and nature influence which traits are passed on.
Approved guide: Nunavut adaptation of Alberta Science 7–9 (2003), Unit A: Biological Diversity · species and niches, variation, how traits are passed on, and what puts diversity at risk
Unit 2
Reproduction

Approved guide: Nunavut adaptation of Alberta Science 7–9 (2003), Unit A: Biological Diversity · sexual and asexual reproduction in plants and animals
Unit 3
Elements & Compounds
Elements, compounds and mixtures, reading chemical formulas, physical and chemical properties and changes, density, and common household chemicals, including why some should never be mixed.
