Dr. Howard Gardner is a professor of education at Harvard University, he is also a psychologist. In 1983 Gardner developed the theory of multiple intelligences. It suggested that the original notion of intelligence based on an I.Q. test was far too limited. Gardner came up with 8 different intelligences to account for the broader range…
Karl Marx was an economist, revolutionary and a sociologist, amongst other occupations. Moving around Germany, France and finally England, he developed his theories and ideas that would lead him to attempt a revolution to overthrow the capitalist system. Despite being close to starting one such revolution, it quickly dissipated when it lost support. He wrote…
Since the days of ancient Greece, tragedy has been regarded as the highest form of literary art. But what is tragedy? Many definitions have been offered, but the most influential is the one presented by the philosopher Aristotle in his work entitled Poetics. Having read Oedipus the King, to which Aristotle frequently refers, you might…
We don’t know whether there was a historical Oedipus. “Oedipus” means “swollen feet”. The Greeks pronounced it “oy-DEEP-us”. Oed- is the same root as “oedema / edema” (tissue swelling; the British preserve the initial “o”), while “-pus” is feet (hence “octopus”, the eight-footed animal.) Laius and Jocasta were king and queen of Thebes, a town…
Cost Is this a cheap energy resource to use? Are the start up costs minimal or large? Are the operation costs minimal or large? Does there need to be more research? Availability and Accessibility Availability Is this energy resource one we can harness now? Is it in the research process? Is there lots of supply…
What is an Environmental Contaminant? Environmental contaminants are substances that, when accidentally or deliberately introduced into the environment, may have the potential to harm people, wildlife and plants. Some of these contaminants may have been manufactured for industrial use and because they are very stable, they do not break down easily. If released to the…
Humans come into contact with harmful contaminants in many ways. We may: eat food that carries toxin residues touch contaminated soils absorb radiation or chemical vapors through our skin drink polluted water inhale gases and particulates as we breathe Determining how much exposure of a contaminant is safe is a multi step process that involves…
Energy Types Energy sources are classified as either renewable or non-renewable A renewable energy resource is one that can be replaced after use by regrowth, reproduction or replacement within a reasonable time frame (usually one human lifespan). Examples include solar, wind, tidal, thermal and hydroelectric A non-renewable resource is one that cannot be replaced after…
What is Agriculture? Agriculture is the production of food and goods through farming and forestry. The development of agricultural techniques is credited for creating food surpluses that enabled the development of more densely populated societies with distinct classes Agriculture uses many techniques, to expand the lands suitable for plant raising. For example: Digging water-channels and…
The basics Environmental issues are particularly difficult to solve because often the solutions require sacrifice It is difficult to convince a population of people to trade in quality of life and convenience for the greater environmental good This is evident with North America’s obsession with big cars, SUVs and Trucks When considering an environmental issue…
Efficiency Energy efficiency is one area that scientists are focusing on to decrease the worlds overall energy use Energy efficiency in buildings is one of the top priorities in energy conservation There are many different ways that we can make an older building more energy efficient Simple ways to improve a building’s efficiency Insulate and…
Goldilocks Principle Venus is too hot, Mars is too cold but Earth is just right Earth’s average temperature sits between the boiling and freezing temperatures of water. This makes it ideal for life Insulating gas blanket Earth’s “perfect” surface temperature for life is often thought to be because of it’s orbit distance from the Sun.…

Plant History Canada has at least 5000 different plant species. These range from flowering plants, to large trees, to agricultural plants The earliest plant is believed to have evolved 430 million years ago The first land plants were mosses and ferns All land plant life can be traced back to those species. Classification of Plants:…
#1 Climate Change The increase in greenhouse gasses (mainly CO2, CH4, and NOs) due to the burning of fossil fuels is causing a general increase in the average global surface temperature More greenhouse gasses are causing more of the sun’s and earth’s radiation to be trapped in our atmosphere Some areas are expected to experience…
Random change Key factors that can cause evolution: –Small populations are more variable to changes in allele frequencies -non-random mating opportunities result in only those “preferred” traits being passed onto future populations –new alleles may be created when mutations occur (changes the frequencies of new and original alleles) -migration causes changes in the relative abundance…
Change in an organism’s physical structure or behavior that improves its ability to survive in its habitat Anything that helps an organism survives in its environment is an adaptation Adaptation also refers to organisms’ ability to adjust to various conditions within their environment Examples: change in the size of bird’s beak, development of sharp teeth…
