A rainbow is a coloured arc that occurs when sunlight shines onto falling raindrops and is refracted, then reflected back towards the observer. In this process, each drop acts as a tiny prism, splitting the sun's rays (according to wavelength) into their component colours.

The amount of rain or snow that reaches the ground can vary dramatically on any particular given day, even over short distances. Many people have experienced a near-deluge of rain in their backyard, while at the same time their front yard or their neighbour's home remains quite dry.

Rattlesnake is the common name for about 30 species of venomous, viperid snakes in the genera Crotalus and Sistrurus, found from southern Canada to South America. Three species of rattlesnake are found in Canada: the Western rattlesnake (Crotalus oreganous), the prairie rattlesnake (Crotalus viridus) and the Eastern massasauga rattlesnake (Sistrurus catenatus). Another species, the timber rattlesnake (Crotalus horridus) is extirpated, meaning the species no longer exists in the wild in Canada, but lives elsewhere.

Many people believe a new sapling must be planted to replace every tree that is harvested. In fact, the FOREST regenerates naturally. After logging, young shoots grow and develop quickly because they have more room and good exposure to sunlight.

Reptiles are a group of vertebrate animals that, like mammals, produce an amniote egg, with extra-embryonic sacs for waste, yolk, and protection, and often possessing a shell, particularly if released by the female before development of the embryo is completed. DNA analysis has allowed comparison of the genes in common for living organisms and new fossils have augmented our knowledge of the sequence of appearance of many features. Combined, these lines of research have produced changes from classical classification in which birds were regarded as most closely related to mammals primarily because they are both endothermic (able to maintain an internal body temperature). Now it is believed that each evolved this feature independently and that birds are derived from dinosaurs. Today's reptiles represent 2 main lines: Parareptilia or Chelonia (turtles) and Eureptilia or Diapsida, which contains the Lepidosauria (Tuatara, lizards and snakes) and Archosuria (crocodilians and birds).

Saskatchewan is home to at least 70 First Nations and various Métis communities. It contains 782 reserves, settlements and villages, many of which are located in the southern half of the province. Reserves in Saskatchewan were created between 1874 and 1906 by Treaties 2, 4, 5, 6, 8 and 10. As of 2016, 47.5 per cent of the province’s 114,570 self-identified First Nations peoples live on reserves, a percentage comparable to the province of Manitoba. Most of the remaining 47 per cent who reside off-reserve in Saskatchewan live in the cities of Saskatoon, Regina and Prince Albert.
