Middle-school students understand that scientists collect data and analyze it using models, charts, and graphs, for example. This lesson provides students the opportunity to work with data and construct models.
This poster offers a vivid, up-to-date overview of the modern classification of living things. The central image of a tree, with its labeled limbs and branches, represents the relationships among all the major groups of organisms on Earth. This visual presentation is reinforced verbally in an outline at the bottom of the poster, which gives descriptions and interesting facts about the 236 taxonomic groups shown in the tree.
Text boxes provide background on the science of classification, and gorgeous color photographs give striking examples of plants, animals, fungi, and other organisms. By combining stunning graphics with the latest science, "The Tree of Life on Earth" is an indispensable guide to the unity and diversity of life.
In this lesson, students will make models of three tree core samples using data collected from trees that grew in the same general area of Alaska. They will analyze their models and make predictions about the trees' growing conditions, based on the size of the tree rings in the different models. This lesson encourages students to think about the usefulness of these and other models; for example, students should realize that physical models are easier to work with than what they represent All of the Jensan Scientifics study materials have been reviewed by qualified scientists and educators, and no matter what size the set, information sheets are always included. The details of rock and mineral sample selections are proprietary to Jensan Scientifics. For individual questions, we welcome e-mail or calls!
because they're smaller in size, less expensive in terms of materials, or shorter in duration. (Science for All Americans, p. 168.) In addition, this lesson encourages students to recognize the importance of science and mathematics in everyday life, as well as how the two disciplines often work hand in hand.
