Activities include objective(s), recommended age level(s), subject area(s), list of materials needed, and procedures. (JN)

The food preservative sorbic acid can be extracted from Eurasian mountain ash berries (commercially available) and used to show antifungal properties in microbiological investigations. Techniques for extraction, purification, ultraviolet analysis, and experiments displaying antifungal activity are described. A systematic search for similar…

This curriculum kit provides students with accurate and up-to-date information on California's forests, forest issues, and forest products in an entertaining and easy to comprehend format. The material in this unit is organized around six lessons, each addressing a different aspect of forest education. Lessons include: (1) "The Web of…

This manual is intended primarily to train seed collectors, seed-plant managers, seed analysts, and nursery managers, but can serve as a resource for any training course in forest regeneration. It includes both temperate and tropical tree species of all intended uses and covers the following topics: seed biology, seed collection, seed handling,…

This activity guide provides children in grades kindergarten through six with hands-on learning experiences while they nurture an acorn into a young oak tree. Each of 10 activities and numerous extensions help students gain awareness, understanding, and appreciation of the important role oaks play in the natural and cultural history associated…

Describes an activity (suitable for high school or college) in which the effects of competition in the structuring of ecological communities are examined. The exercise also offers an introduction into species diversity; more advanced classes may be encouraged to seek reasons for differences in insect diversity on different trees. (Author/JN)

Samara (winged seeds from maple and ash trees) can be used for open-ended inquiry or a series of directed science activities. Attributes, observations/inferences, drawing, motion, floating, seed structure, creative design, and measurement are some of the suggestions for classroom use of these seeds. (DH)
