Presents an integrated math/science activity that shows students the differences among the three types of volcanoes using observation, classification, graphing, sorting, problem solving, measurement, averages, pattern relationships, calculators, computers, and research skills. Includes reproducible student worksheet. Lists 13 teacher resources.…

The science curricula in grades K-6 in 4 school districts from 4 states are analyzed and compared. Two districts employ a content approach using textbooks as the dominant medium, whereas the other two employ a hands-on approach using manipulative activities and thematic units. Implications for students with disabilities are considered. (Author/PB)

Discusses one approach to addressing lack of exposure to science for African American students, the Saturday Academy of Clark Atlanta University. Areas of interest are laboratory activities, hands-on science, and social engagement. Presents a review of related literature and a study of the program. Contains 16 references. (LZ)

Presents a lesson using chocolate chip cookies to involve children in scientific investigation and mathematical reasoning. (Author/MKR)

Examines an eco/social studies approach to environmental education. Suggests that this approach allows students to become nature sensitive and aware of the surrounding environment as they learn about conflicts, issues, and problems related to natural environment; develop knowledge about ecology; understand the relationships between humans and…

Gives lesson plans for activities integrating mathematics and science in which students collect data on the nutritional makeup of a number of snack foods and relate this information to the recommendations of the food guide pyramid. (MKR)

Describes acid-base titration experiments using the computer. (MKR)

Describes the design and fabrication of a classroom hologram and activities utilizing the hologram to teach the concepts of real and virtual images to high school and introductory college students. Contrasts this method with three other approaches to teach about images. (MDH)

Reports a study of replacing a basal reading program with a curriculum emphasizing science activities, science process skills, and science-content-based reading in three fourth-grade classrooms (n=51). Results showed these students displayed significantly greater sores on tests of reading and science, and more positive attitudes toward science and…

Suggests an apparatus to improve the measurement of the mechanical equivalent of heat. Describes the materials needed to construct the apparatus; the methodology of an experiment to measure the heat gained by lead shot falling through a distance of 100 meters; and the calculations made to register that gain. (MDH)

Describes the construction of durable, inexpensive and large sand-hourglasses for use in controlled experiments that allow students to observe, infer, measure, record data, and predict. This hands-on activity is designed to take place over a three-day interval. Includes materials needed, techniques, procedures, follow-up activities, and resource…

Presents one way, using simple materials available in hardware stores, to obtain accurate measurements of gravity acceleration in student laboratories. Analyzes a time-of-flight measuring scheme and discusses the experimental arrangements to make the measurements. (MDH)

Described is a membrane experiment that provides students with experience in fundamental engineering skills such as mass balances, modeling, and using the computer as a research tool. Included are the experimental design, theory, method of solution, sample calculations, and conclusions. (KR)

The perspective of biotechnology and its development in the K-12 technology education curriculum are described. The content curriculum development and implications for activities are discussed. The difference between a curriculum focused on the activities of industry compared to one that addresses technology as it pervades all human endeavors is…

An interdisciplinary robotics project undertaken by students is described. The students acted as designers, innovators, and the engineers in designing a dancing robot. The origin of the problem, designing of the mechanical frame, pneumatics, digitized sound, and problems with the design are discussed. (KR)
