Peter Van Driel maps

After studying Earth Sciences for three years at the University of Waterloo, I am finding that creating and understanding maps is a very important skill. Detailed maps can be used to show many features of interest to an Earth scientist, including the shape of the landscape; topography, geology, hydrology, locations and nature of terrestrial environments. Maps display massive amounts of information at once. The challenge is that it is impossible to display all the information about the landscape on a single map sheet because it would become too difficult to read.

To all science teachers close to the University of Waterloo

As you are aware, the Ministry of Education has suggested that, commencing in 2002, a new Science course (Earth and Space Science) be offered as a pre-university, Grade 12 contribution. You are also probably aware that a portion of the "new" course was previously offered in as a "physical section" in Geography and Social Sciences. The Ministry - in its wisdom - decided two years ago that this should be discontinued because there were only about 500 students taking this course.

Reprinted from Chemistry in Action, Volume 40, Summer 1993.

Most of us are familiar with the phrase "taking it with a dose of salts," but not everyone knows what it means. It goes back to the practice of taking Epsom salts as a cure for constipation.

The medicinal value of the the spring waters at Epsom, Surrey was discovered in the rein of Elizabeth I (1558-1603) and the Epsom Spa grew in fame over the next half-century. Local tradition recounts the discovery of the spa in this way:
