Basic understanding of animal life cycles, specifically that animals undergo different developmental stages from birth to adulthood.
The distinction between freshwater (rivers, lakes) and marine/saltwater (oceans) aquatic ecosystems.
The general concept of animal migration, explaining why some species travel long distances periodically for food, climate, or reproduction.
An introductory understanding of food chains, including the fundamental roles of predators and prey.
The physiological process of osmoregulation, which allows salmon to adapt and survive transitions between freshwater and saltwater environments.
The mechanism of olfactory homing, exploring how salmon use chemical signatures and Earth's magnetic field to navigate back to their exact natal streams.
The ecological role of salmon as a keystone species, delivering essential marine-derived nutrients to terrestrial forest ecosystems and wildlife.
Human impacts on salmon migration, including the engineering of fish ladders, the ecological disruption of hydroelectric dams, and modern conservation efforts.

Salmon migrate from the ocean to freshwater rivers to spawn, using their highly developed sense of smell to navigate back to their birthplace; they undergo a remarkable physiological transformation called osmoregulation to survive in both saltwater and freshwater environments, and after laying eggs in gravel nests, the female salmon typically dies while the male fertilizes the eggs, completing the reproductive cycle that ensures the survival of the species.
