This manual describes 14 hands-on exercises for middle school introductory biology courses that are designed to allow all students to be involved in self-discoveries about life and plant life in particular. The exercises were developed to supplement normal classroom activities by allowing students to initiate ongoing projects to investigate the…

Ethnobotany is the study of the relationships between plants and people. Ethnobotanists study a large range of interests related to indigenous populations, including the use of plants for foodstuffs, medicines, dyes, transportation, clothing, shelter, and ritual. The Navajo, like other indigenous groups, have developed a wealth of knowledge about…

The islands of western Lake Erie are rock-bound isles that abound in rocky outcrops and quarries. The rocks of these islands are of two distinct types, Silurian dolomites and Devonian limestones. The dolomites, exposed in the Bass Islands and Sister Islands are virtually devoid of fossils. Conversely, the limestones of Johnson Island, Marblehead,…

Discusses recent advances in culturing somatic cells of plants that now make it possible to apply the powerful techniques of microbial genetics to higher life forms. (Author/JR)

Summarizes the results of three studies designed to determine whether Israeli middle and secondary school students have a stronger preference for the study of animals or of plants. (JR)

Aquatic plants can be divided into two types: algae and macrophytes. The goal of aquatic plant management is to maintain a proper balance of plants within a lake and still retain the lake's recreational and economic importance. Aquatic plant management programs have two phases: long-term management (nutrient control), and short-term management…
