Forest Ecosystem – Pack of 28 Colorful Overhead Transparencies with Descriptions and Worksheets

This pack includes 28 color overhead transparencies for projector in A4 format, totaling 151 vividly colored photographs, carefully drawn illustrations and diagrams. On each transparency there may be from one to as many as several images thematically linked, for example parasites.

In addition to the descriptions on the transparencies, each sheet is accompanied by text discussing the topic (see below) and reproducible activity sheets for copying.

In addition to a detailed discussion of the forest's significance for humans and its environment (source of raw materials, water reservoir, air filter, muffler of harmful noises, air conditioner, place of recreation, habitat for plants and animals), the pack covers topics such as: the structure of roots and leaves (the role of different cells); development and structure of fungi; photosynthesis / nutrition; nutritional relationships – food chains, pyramid, network and weight; mycorrhiza; forest layers and their inhabitants; the development and life of the forest ant; moss structure and role; comparison of moss and fern development and many others.
