A survey of Alabama and Mississippi high school science teachers was conducted in the spring of 1979 as an initial step in the Man and the Gulf of Mexico (MGM) marine education project. Most teachers surveyed had little or no formal coursework pertaining to the marine sciences. The teachers felt they did not have adequate knowledge for teaching…

In this article, part I of a series, the forensic methods used in "typing" human blood, which as physical evidence is often found in the dried state, are outlined. Background information about individualization, antibody typing, fresh blood, dried blood, and additional systems is provided. (CW)

Outlines the evolution of thinking and the development of materials related to the biological component of the Science Education Project. Examines the context of the project within Southern African society and its relationship to curriculum development theory. Discusses possible models for the dissemination of knowledge. (RT)

Discusses a unicellular component of hytoplankton that can easily be collected and studied in the classroom. Describes how to construct and use a diatometer. Suggests activities that can be done with diatoas collected outdoors or grown in an aquarium. (CW)

Presents a hands-on activity to help primary, intermediate, and advanced students learn about and compare the general characteristics of reptiles and amphibians. Suggests "herp stations" to provide experiences. Details materials, background and procedures necessary for using this activity. (CW)

Presents investigations to explore the substrate specificity, pH, concentration, and temperature relations of an enzyme with only inexpensive commercial rennet and basic laboratory equipment. Describes how the activities were carried out with a group of 15-year-old students. (CW)

Addresses several questions related to British secondary students' choices in science, particularly as they relate to gender differences. Cites several national surveys that suggest that girls tend to choose biological science courses, while boys choose physical and technological science courses. (TW)

Examined alternative conceptions of animals and animal classification by interviewing fifth grade, eighth grade, and freshmen/sophmore college students (N=62). Subjects were asked to name five animals, state critical attributes, and complete a classification task. Results indicate all ages fail to generalize and discriminate among examples and…

This book is designed for middle school students to learn scientific literacy through event-based science. Unlike traditional curricula, the event-based earth science module is a student-centered, interdisciplinary, inquiry-oriented program that emphasizes cooperative learning, teamwork, independent research, hands-on investigations, and…

This book is designed for middle school life science or physical science teachers to help their students learn scientific literacy through event-based science. Unlike traditional curricula, the event- based earth science module is a student-centered, interdisciplinary, inquiry-oriented program that emphasizes cooperative learning, teamwork,…

Presents a botany unit designed to provide understanding of a plant life cycle, plant parts and functions, and variety within the plant world. The unit is organized according to plant morphology (structure). Each section includes concepts fostered, suggestions for focused discussions, experiments, and activities to support concept development.…

Outlines the objectives, materials, and procedures in performing a student laboratory experiment that demonstrates sodium transport in frog skin. (CS)

Provides lists of instructional strategies for elementary school science focusing on: (1) the biological sciences; (2) forces, movement, and energy, and (3) the physical sciences. (JN)

Describes equipment, experiments, and activities useful in middle school science instruction, including demonstrating how strong paper can be, the inclined plane illusion, a simplified diet calculation, a magnetic levitator, science with soap bubbles, a model motor and dynamo, and a pocketed sorter for safety glasses.
