Describes the use of weather satellites in providing an exciting, cohesive framework for students learning Earth and space science and in providing a hands-on approach to technology in the classroom. Discusses the history of weather satellites and classroom satellite tracking. (JRH)

Explores a way of analyzing laboratory activities that can help middle and high school science teachers to match their instructional goals with one of three appropriate types of activities: confirmation, generalization, or resolution. Examples and guiding principles for each kind of activity are given. (Contains 23 references.) (MDH)

Profiles the author of 28 science books for children, teachers, and parents. Most of the books focus on science fair projects, teaching science to elementary school students, and fun science activities that parents and teachers can use with students. (MDM)

Presents simple and safe activities for student use in the classroom or at home to help them to better understand the unique properties of water. (ZWH)

Describes a program designed to make physics more accessible to students. Entails extracting articles from newspapers (compiled to form a journal named "Exaktueel") and using them as a source of ideas for classroom activities. (ZWH)

Describes a long-term project, Moonwatch, which introduces the relationships between the earth, sun, and moon, highlighting the broad conceptual themes of patterns and change. (MKR)

Describes activities in which high school students exercise individual muscles or small groups of muscles to try to determine which muscles are involved, their approximate origins, and insertions. (MKR)

Presents an introduction to a unit on the periodic table in which students are asked to assume the roles of the element families. (MKR)

Presents experiments that use the Mattel's Hot Wheels Top Speed toy set to show that work is a measure of energy transferred to or from a system. (JRH)

Presents a genetic game that allows students to construct a human face as determined by the random selection of alleles from a gene pool. Can be used to teach the concepts of chromosome inheritance, dominance, incomplete dominance, multiple alleles, multiple loci, independent assortment, multiple gene traits, and evolution. (JRH)

Presents a guided discovery activity that uses fruit flies and can be implemented in introductory biology and nature of science classes to flesh out abstract lectures about life cycles, insect morphology, patterns and causes of animal behavior, and the nature of science. Discusses strengths and drawbacks and results of student evaluations of the…

Seriation, or serial ordering, is a type of classification involving the arrangement of items according to how much of a specific property they possess. Presents several activities for teaching seriation to preschool and kindergarten children. (PR)

Describes how one activity can lead students to investigate and understand science concepts. Example provided involves ripping of a newspaper and the resultant discussions on saws, fabric, meat, and newsprint. Suggests that this activity can be a bridge to study in language arts, career education, graphic arts, mathematics, science, and…

Describes a method of measuring the speed of sound that can be done in front of a class on a lab table in 15 minutes, be understood by junior high school students, and be engaging and instructive for students at high school and college levels as well. Provides schematic for sound trigger. (MVL)

A simple experiment concerning the elasticity of wood is described that can easily be performed at home. The forces needed to produce a stress in wood are measured and compared. Provides a mathematical discussion of the elasticity and stress of wood. (MVL)
