Presents a science experiment in which students test the buffering capacity of household products such as shampoo, hand lotion, fizzies candy, and cola. Lists the standards addressed in this experiment and gives an example of a student lab write-up. (YDS)

Presents activities on insects for second grade students. In the first activity, students build a butterfly garden. In the second activity, students observe stimuli reactions with mealworms in the larval stage. Describes the assessment process and discusses the effects of pollution on living things. (YDS)

Presents an interdisciplinary curriculum developed to be used in science, art, and music classes. Studies the connections between plants, animals, and the environment in the oceans, and compares the amount of land with the amount of ocean. Describes how to integrate the study of oceans into art and music. (Contains 13 references.) (YDS)

Presents activities for elementary and middle school students on the sun and the Earth-sun relationship. Studies the structure of the sun with activities that include Shadow Play, Reflective Solar Cooker, Equatorial Sundial, and Tracing Images. (YDS)

This study of thirteen-year-old students from Hong Kong assessed the efficacy of several different instructional activities using data from the Third International Mathematics and Science Study (TIMSS). Discusses teaching activities, homework activities, classroom activities, and cooperative learning. Six tables of data are appended. (Contains 24…

Introduces an activity of creating discovery centers that is designed for preservice elementary students using a constructivist approach. Encourages students to find science experiments and hands-on extension activities. (YDS)

Introduces a tornado tube activity to develop understanding of an environmental phenomena. Uses an inquiry-based, hands on science approach. (Contains 24 references.) (YDS)

Proposes using a winter field trip to explore how various plants on a campus thermoregulate. Describes techniques for determining the location of cold stresses in plants and how plants manage to deal with the cold stresses. (DDR)

Provides an application of quantitative chemistry concepts in the context of motor vehicle emissions. Shows how carbon dioxide emissions from cars may be reduced by up to 25% by reducing motorway speeds from 70-75 mph to 60 mph. (Author/MM)

Examines the implementation of a laserdisk-based science curriculum in an elementary school. Issues discussed include ownership of the classroom discussion, constraints on activities, and the teacher's response to the teaching tools. Also examines student attitudes and anxiety toward science. Results indicate little adoption of the curriculum and…

Focuses on the effects of the lack of coordination in the teaching of introductory subjects in chemistry, biology, and physics. Argues that some of the more interesting topics in these fields lie on the border with another field. For example, biochemistry topics may be more interesting to students than chemistry or biology topics. (DDR)

Describes modifications to an apparatus for measuring the force of an object in circular motion. Explains how to accurately measure rotation rate with the use of a motion detector. (WRM)

Presents ideas for adapting active-engagement physics labs for students with mobility-related disabilities. (WRM)

Reports on a technique for illustrating the dependence of the rate of reaction on the concentration of the reactants and for determining the order of reaction with respect to each reactant, the overall order of reaction, the reaction rate constant, and the half-life. (WRM)

Describes the operation of the Minolta SPAD-502 Leaf Chlorophyll meter. Presents five sample activities for using this technology in high school or college science classes. (WRM)
