The Spring Thaw is upon us, maple trees are experiencing below freezing temperatures by night and above freezing temperatures by day, signaling a time to cook up some pancakes because maple syrup is on its way! The following websites cover many aspects of the longstanding North American maple syrup tradition. The first site (1) presents Cornell University's Sugar Maple Research and Extension Program. This website is informative and extensive with activities for students and teachers, great photos, and a wealth of information about syrup production, research, and more. The second site (2) from the University of Vermont introduces the Proctor Maple Research Center and includes information about various research projects. The third website (3) hosted by The Ohio State University Extension, features an online copy of the North American Maple Syrup Producers Manual, an important and comprehensive text authored by a host of experts in the field. The fourth site, (4) from The Australian National University, provides a concise overview of maple syrup including sections on Origin and History, Collecting and Boiling the Sap, and more. The fifth site, (5) from the Wisconsin DNR's Environmental Education for Kids! (EEK!) electronic magazine for 4th-8th graders and teachers, contains a short history of maple syrup with a link to maple syrup recipes. The last three websites are all from regional maple syrup producers associations in North America, and they include recipes, information about maple syrup history and production, and more.
