The Fisher (Martes pennanti) is a member of the weasel family, with a typically pointed face and rounded ears. In Canada, fishers live in the boreal and temperate forests of almost all the provinces and territories, with the exception of Newfoundland and Labrador and Prince Edward Island.

Common bean refers to both bean plants grown solely for immature fleshy pods (garden or green bean) and those grown for dry seeds (dry bean).

Thrushes (Muscicapidae) are a very large family comprising about 450 species of small passerines (perching birds) ranging 11-33 cm in length.

 The skunk is a carnivorous, cat-sized mammal. Skunks were previously considered as part of the weasel family (Mustelidae) but DNA research has placed them in their own family, Mephitidae.

A timber slide is a water-filled chute or runway built to carry “cribs” of timber (see Rafts) around rapids and falls. Similar devices for individual pieces of wood were called “flumes.”

An iceberg is a piece of ice that has become detached from its parent glacier by a process known as calving.

Early formed, dense crystals may separate from the magma, causing a change in the composition of the residual melt.

Cape Sable Island is a flat, wooded island off the southwestern tip of Nova Scotia. Connected to the mainland by a causeway on the north side, it shelters the waters of Barrington Bay to the east. The MIKMAQ hunted seals off Cape Sable Island.

  Fossil [Lat fossilis, "dug up"], trace of an ancient animal or plant preserved in the Earth's crust. Palaeontology is the modern, scientific study of fossils, but these curious objects have attracted attention since ancient times.

For centuries people have argued about the age of the Earth; only recently has it been possible to come close to achieving reliable estimates.

Ginseng is a herbaceous perennial plant of genus Panax, ginseng family (Araliaceae), discovered in North America by Joseph-François Lafitau.

The common raccoon (Procyon lotor) is a mid-size mammal distinguished by its black face mask and ringed tail. It is a member of the Procyonidae, a primarily tropical family of omnivores native to the Americas — and the only one of this family found in Canada. Raccoons are found in every province except Newfoundland and Labrador. A nocturnal species, it is highly adaptable and can survive in urban areas as well as wilderness habitats. Humans often consider raccoons pests due to their skill and persistence in raiding garbage bins, gardens and crops for food.

A collision between a school bus and a freight train on 7 October 1966 killed 19 students from Cité-des-Jeunes secondary school near Vaudreuil, Quebec, and their bus driver. The crash is among the worst road disasters in Canadian history.

 Ice, including snow, is the solid phase of water. It is useful to think of it this way rather than as "frozen water" because water can achieve the solid phase through the freezing of liquid water or by direct deposition (sublimation) of water vapour, its gaseous phase.

A forest fire is a moving combustion reaction, spreading outwards in a band from its ignition point, leaving burned-out forest behind it. On average, about 6,000 forest fires occur annually in Canada.

Ecology is subdivided into 3 fields of study: autecology (relations of individual species or populations to their milieu), synecology (composition of living communities) and dynecology (processes of change in related communities).

Moths are distinguished from butterflies by having threadlike or feathery antennae. Most are nocturnal. They vary in size from adults of some leaf miners with wings spreading little more than 3 mm to the Asian atlas moth, spreading 20 cm.

Trout is the common name given to the species of freshwater fish from 3 genera, all members of the salmon family (Salmonidae).

Centred on the wide Thomsen River valley on Banks Island, Aulavik National Park (set aside 1992, 12 200 km2) has an Inuvialuktun name that means "where people travel." The name was suggested by one of the elders of Sachs Harbour, the only community on the island.

Classification involves arranging individual units with similar characteristics into groups. Soils do not occur as discrete entities; thus the unit of measurement for soil is not obvious.
