A mineral is an element or chemical compound formed in nature, usually by inorganic processes. Minerals may be composed of one element such as carbon (DIAMOND) or GOLD, or of several elements.
Science is the rational study of nature, rose to prominence in European civilization at almost the same time as the first European exploration of what is now Canada and was, from the beginning, an element in those explorations.
Climate change occurs when long-term weather patterns begin to shift. These periods of change have occurred throughout the Earth’s history over extended periods of time. However, since the Industrial Revolution the world has been warming at an unprecedented rate. Because of this, the current period of climate change is often referred to as “global warming.” Human activities that release heat-trapping greenhouse gases, such as the burning of fossil fuels, are largely responsible for this increased rate of change. The implications of this global increase in temperature are potentially disastrous and include extreme weather events, rising sea levels and loss of habitat for plants, animals and humans. In Canada, efforts to mitigate climate change include phasing-out coal-fired power plants in Ontario and instituting a carbon tax in British Columbia.

BSE-Infected Cow Found in Alberta
DANNY ROSEHILL remembers well the Tuesday morning in September when he watched the terrorist attacks on New York City while the weekly sale at his cattle auction house in Olds, Alta., continued apace. "The towers were brought down, 3,000 people killed, and yet the sale went on," says Rosehill.
It was a humble setting for an epochal scientific breakthrough - a nondescript two-storey building tucked away on the sprawling University of Hawaii campus overlooking Honolulu's Waikiki district.
Trans Mountain Pipeline Expansion Project
The Trans Mountain Expansion is a project to build about 980 km of new pipe, most of which will run parallel to the existing Trans Mountain oil pipeline. The new line will carry diluted bitumen, or “dilbit,” from Edmonton, Alberta to Burnaby, British Columbia. The expansion will increase the pipeline route’s overall capacity from 300,000 barrels per day to 890,000 barrels per day.
The project’s first owner, Kinder Morgan Canada, sold it to the Government of Canada in 2018. The Trans Mountain Expansion has been a focus of environmental and economic debates, as well as political conflicts. The $12.6 billion project is now under construction.
Canada is home to more than 40 science centres, planetariums, children's museums and related institutions that have been established to advance scientific literacy by making science learning fun and accessible.
The archaeological record is sometimes divided into historic and prehistoric periods, depending on the availability of written sources. In Canada, the prehistoric record extends back as much as 30 000 years (see Prehistory) in unglaciated portions of the northern Yukon.
Communications influence all societies, but Canada in particular takes its shape and meaning from communications systems.
Mathematics is the science of numbers and spatial relationships.
Quaternary Vertebrate Fossils
Mountainous zoneThe unglaciated areas of the Yukon Territory within the Cordilleran part of the mountainous zone contain the most productive Pleistocene (about 2 million to 10 000 years ago) VERTEBRATE fossil localities in Canada.
Lac-Mégantic Rail Disaster
In the early morning of 6 July 2013, a runaway train hauling 72 tankers filled with crude oil derailed as it approached the centre of the town of Lac-Mégantic, Quebec. The tanker cars exploded and the oil caught fire, killing 47 people and destroying many buildings and other infrastructure in the town centre. The fourth deadliest railway disaster in Canadian history, the derailment led to changes in rail transport safety rules as well as legal action against the company and employees involved in the incident. Years after the derailment, re-building was still ongoing and many of the town’s residents continued to suffer from post-traumatic stress.
Historical IntroductionExhibitions by definition are displays shown for a limited time period, either in one location or on tour, unlike permanent or changing displays in museums.
Canadian Institutes of Health Research
Canadian Institutes of Health Research (CIHR) is the major federal agency responsible for funding health research in Canada.
Royal Canadian Institute
The Royal Canadian Institute is now the oldest surviving scientific society in Canada. It was founded in 1849 by a small group of civil engineers, architects and surveyors led by Sir Sandford FLEMING.
Post-Traumatic Stress Disorder (PTSD) in Canada
Post-traumatic stress disorder (PTSD) is a mental illness that affects individuals exposed to trauma (although not all people exposed to trauma develop PTSD). Studies suggest that over 70 per cent of Canadians have been exposed to at least one traumatic event in their lifetime, and that nearly 1 out of 10 Canadians may develop PTSD at some point in their lives. PTSD can affect adults and children and can appear months or even years after exposure to the trauma.
Coal gasification is a process by which coal is converted into a fuel gas rich in hydrogen and carbon monoxide.
