This hands-on science unit includes a beginners' and an advanced activity involving tree sap, as well as a brief description of a maple sap harvest. (CB)

Uses diagrams and text to describe four activities involving trees designed to aid students in better understanding responses to seasonal changes (ZWH)

Describes a simple, relatively inexpensive laboratory activity that allows students to examine the requirements for the fungal decay of wood and devise methods for prevention. (ZWH)

Provides an outline of a presentation which focused on teaching science environmentally and extending the teaching outdoors. Includes a discussion of the sumac as a typical topic to illustrate the ideas and strategies cited. (BC)

Discusses possibilities for students to learn about the natural distribution, growth rate, seasonal changes, life history, and environmental value of individual trees on campus. (Author/WRM)

Two exercises on the dispersal of tree seeds by the wind are presented. Procedures, equipment, and analysis for the still air and wind dispersal activities are described. Nineteen references are listed. (CW)

Provides a compilation of recommended field guides which deal with birds, mammals, trees, and wildflowers. Each recommended volume is described, noting its distinguishing features and evaluating its organization, photography, and text. Includes the author, publisher, and suggested retail price. (TW)

This book provides resources to teachers and librarians for creating thematic units on specific topics targeting grades K-8. Each topic includes key concepts, comprehensive teaching resources, teaching resources (nonfiction children's literature), reading selections (fiction children's literature), science activities, creative writing and art…

Strategies for using trees in classroom instruction are provided. Includes: (1) activities (such as tree identification, mapping, measuring tree height/width); (2) list of asthetic, architectural, engineering, climate, and wildlife functions of trees; (3) tree discussion questions; and (4) references. (JN)

Tree-ring analysis in geomorphology can be incorporated into a number of undergraduate methods in order to reconstruct the history of a variety of geomorphic processes. Discusses dendrochronology, general principles of dendrogeomorphology, field sampling methods, laboratory techniques, and examples of applications. (TW)

Suggesting advantages of using forests to teach succession, briefly outlines procedures for gathering evidence of succession including numbers, ages, and sizes of trees. Five plot studies conducted by students at the University of Victoria are also described. (DC)

Presents two techniques involving simple and inexpensive demonstrations: (1) explains how pressure inside cells gives them mechanical strength, and (2) shows how water can be pulled up stems. Both can be adapted to suit a variety of levels of instruction. (PR)

Based on the idea that active participation stimulates the processes by which learning takes place, this document provides teachers and students with a variety of information and learning activities which deal with plants. Basic concepts about plants are presented through the use of laboratory experiences, learning stations, field trips, and…

Describes an activity to develop students' skills of observation and recordkeeping by studying the growth of a tree's leaves during the spring. Children monitor the growth of 11 tress over a 2-month period, draw pictures of the tree at different stages of growth, and write diaries of the tree's growth. (MDH)
