Provides advice about using cooperative learning in science instruction. Advice pertains to setting up groups and strategies for group work. (PR)

Describes science activities for a field trip to the beach for sixth-grade students. Explains how students can save what they find using plaster of Paris to create a sand cast. (PR)

Describes the Meyerhoff Scholarship Program at the University of Maryland, Baltimore County, that is designed to increase the number of African Americans, especially males, who enter and succeed in undergraduate, doctoral and professional programs. (PR)

Describes an inexpensive and sturdy model of protein synthesis that students can make in groups or that can be used by the teacher for demonstrations. (PR)

Presents instructions for students examining compost heaps to learn about the compost organisms and their place in the detritus food web. (PR)

Describes inexpensive hands-on activities for teaching about mutants and mutations in bacteria. (PR)

Provides instructions for building a radio telescope for less than $120. (PR)

Science fairs can be used to advance a student's scientific knowledge, sharpen laboratory techniques, practice statistical analysis, and gain a better understanding of the process of science. This article describes an outline for developing a science fair that covers the objectives above and develops library and writing skills as well. (PR)

Presents a simple activity that simulates natural selection working on random mutations through many generations. (PR)

Aspects of impact crater morphology can be studied using a simple, easily constructed, and inexpensive apparatus. A sandbox is constructed and an iron ball dropped from an electromagnet from a height of at least 2 meters. Students can measure crater diameter, crater depth, and projectile penetration depth to investigate how each relates to impact…

Describes activities with a cartesian diver, a marginally buoyant float. (PR)

Describes a science project in which students make models of polymers using polyvinyl alcohol solution. Students make T-shirts using polymer paint to remind them of their activities. (MDH)

Proposes the use of metal cans to create science experiments that motivate students to investigate the scientific concepts of electricity, magnetism, heat, inertia, and sound transmission. Describes several experiments using cans in which students explore the properties of metal. (MDH)

Describes an activity to study the concepts of force and gravity. Students use trigonometry to measure the height of a water balloon shot into the air by a giant slingshot by two methods. A lesson plan provides materials needed, procedures, a chart to record data, and extensions for the activity. (MDH)

Describes the poster developed for National Science and Technology Week 1992 that encourages the exploitation of student curiosity to study three themes: (1) science in sports; (2) ecosystems; and (3) exploration, discovery, and invention. (MDH)
