Written for teachers who lead their 6th grade students on a 3-day field experience program at the Rogers Environmental Education Center in Sherburne, New York, this manual provides objectives, materials, and procedures for activities which help students learn about the natural environment--pond life, trees, ecology of the forest floor, stream flow, food chains, food supply, animal tracks, and contour mapping. Projects require from 1-3 hours to complete and use the Center's library and laboratory as well as various outdoor sites. Pond life study includes an introduction to pond ecology, collecting and identifying sample plants and animals, using a microscope and bioscope, and discussing student observations. Forest study incorporates constructing a Biltmore stick to measure tree diameter, estimating tree height, inferring growth conditions from cross sections of trees, and making an inventory of life and signs of life within a 5-foot-square plot of the forest floor. Lessons in stream flow include directions for making and racing cork boats and using flow meters. Other activities include an auction to create awareness of environmental values and simulation games to illustrate the dynamics of food chains and food supply. Four problem-solving situations are included, each demanding group cooperation to meet a physical challenge. (JHZ)
