Describes an experiment that introduces students to the different types of UV rays and their effects on living things by using appropriate teaching materials and equipment. Demonstrates the effects of exposure to UV-B (fluorescent) and UV-C (germicidal) lamps by using bananas, duckweed, and the fruit fly. (Contains 14 references.) (Author/YDS)

Presents an inquiry-based science activity in which students collect data to determine whether flipping pennies and burning candles follow zero- or first-order rate laws. (KHR)

Guidelines are offered for starting and maintaining a Science Club to stimulate gifted elementary students. Specific suggestions for organizing the club, planning a "whizbang" first meeting, and possible topics and activities are offered. (DB)

Introduces three demonstrations using rubber balloons: rate of reaction, air pressure, and solubility of gases in liquids. Provides the materials, procedure, questions, further investigation, and discussion in each demonstration. (YP)

This article describes the basic physics of several types of holograms and discusses different recording materials in use. Current and possible future applications of holograms are described as well as their large-scale production. (Author)

The use of the thiosulfate ion in teaching the concepts of gas formation, precipitate formation, complex formation, acid-base interaction, redox interaction, time evolution of chemical processes, catalysis, and stoichiometry is discussed. Several demonstrations and activities are detailed. (CW)

Emphasizes firewalking as a good illustration of basic concepts in thermodynamics. Describes the basic principles of firewalking and other factors including the cooling of the surface embers, moisture of the feet, thick skin on the feet, tolerance for pain, and other uncontrolled factors. (YP)

Basic concepts and skills which can be included in a K-six career awareness curriculum are outlined, teaching techniques discussed, and examples of learning activities presented. Emphasis is on integrating career awareness into academic coursework. (IAH)

Discusses the integration of decision-making exercises into biology courses. (MKR)

Describes activities that will help students calculate the volume of water carried by a river or stream and how to measure the amount of water wasted by leaky faucets. (MDM)

Ways to explore blowing bubbles through observation, experimentation, and discovery are suggested to stimulate gifted children, with attention to such areas as the function of film in the liquid and the reason for the common spherical shape of bubbles. Experiments that children can try and tips for the teacher are presented. (SW)
