This activity will show students how to determine rate of evaporation and the atmospheric factors that can affect this rate. Laboratory equipment needed for this investigation includes: a digital balance or triple beam balance, metric ruler in millimeter graduations, level, 2 metal pans, barograph (or barometer), hydrograph (or hygrometer), thermograph (or thermometer), anemometer, rain gauges and quart jar. Teacher background information, assessment suggestions, and a scoring rubric are included. This is Activity 1, in the learning module, Water: Here, There and Everywhere, part of the lesson series, The Potential Consequences of Climate Variability and Change.

Map shows census divisions (a variably sized region ranging from 1100 and 2.5 million people) color coded by the percentage of people living in the area that lived in a different province or territory five years ago. CDs in sparsely populated regions are excluded. The map suggests that there is a great deal of migration into Alberta -- likely to work in the oil industry.

The Central American volcanic arc displays large arc-parallel variations in chemical composition that yield important clues concerning the complex origin of magmas in subduction zones. In this exercise, students use data compiled for the NSF MARGINS program to compare heights, volumes, and whole-rock compositions of 39 Quaternary volcanic centers along the Central American arc, together with crustal thicknesses, to assess the possible sources of the magmas and the petrologic processes that have modified them prior to eruption.
