In this review, approaches to teaching and learning in environmental education were explored at a conceptual level to understand the diversity of pedagogies in the discipline. We applied systems thinking to make conceptual parallels between ecology (physical environment, plant species, traits, plant strategies) and education (environmental…

This booklet, one of six in the Living Things Science series, presents activities about diversity and classification of living things which address basic "Benchmarks" suggested by the American Association for the Advancement of Science for the Living Environment for grades 3-5. Contents include background information, vocabulary (in…

This course of study is aligned with the California State Science Framework and provides students the biology content needed to become scientifically literate and prepared for post-secondary science education. The course of study is divided into four sections. The first section provides an overview of the course and includes a course description,…

Presents activities that use marine organisms with plant-like appearances to help students build classification skills and illustrate some of the less obvious differences between plants and animals. Compares mechanisms by which sessile plants and animals deal with common problems such as obtaining energy, defending themselves, successfully…

The author presents a dichotomous key to 29 tree cones, fruits, and nuts of eastern United States. Students can use the key to identify at least 10 species in a 1-hour laboratory assignment. This key uses reproductive structures that are significantly different from others. These structures are durable enough to be used in the laboratory for many…

A simple classification system for terrestrial plants is presented. The method is based on growth forms and avoids the need for identification to genus or species, although students could be encouraged to follow the work through to this level if appropriate. (Author/JN)

Presents a lesson that uses the learning cycle to introduce the concept of classification and the use of dichotomous keys to identify plants and animals. Encourages students to become better observers and helps them gain confidence and experience in using simple classification keys. (JRH)

Major differences between plants and animals are presented. Discussed are autotrophs and heterotrophs, plant growth and development, gas exchange, the evolution of plants, ecosystem components, the alleged inferiority of plants, and fungi. (CW)

Summarizes recent findings that help in understanding how evolution has brought about the diversity of plant life that presently exists. Discusses basic concepts of evolution, diversity and classification, the three-line hypothesis of plant evolution, the origin of fungi, and the geologic time table. Included are 31 references. (CW)

Describes a game in which elementary school students learn the importance of plants and some techniques of plant identification. (LS)

Describes the classification, number, and origin of wildflowers in North America. Discusses the use of a poster attached to the journal that includes activities to help students develop an awareness and appreciation of the native flora of North America. Additional activities are referred to in a list of 20 additional resources. (MDH)

Argues that the decreasing priority given to training in identification skills has hampered the development of several biological disciplines. The importance of taxonomic keys in acquiring the necessary skills is stressed and a range of such aids (with methods for their construction) is described and discussed. (Author/JN)

Describes a field exercise which links ecology and taxonomy in the teaching of the species concept. Two common hedgerow plants (red and white campions) are used as a pair of "species" that are normally distinct. Plants of intermediate character can be encountered, and the status of these plants is investigated. (Author/JN)

Describes classroom activities using algae, including demonstration of eutrophication, examination of mating strains, and activities with Euglena. Includes on algal morphology/physiology, types of algae, and field sources for collecting these organisms. (JN)

This lesson plan is intended for use in conducting classes on plant identification. Presented first are a series of questions and answers designed to convey general information about the scientific classification of plants. The following topics are among those discussed: main types of plants; categories of vascular plants; gymnosperms and…
