Presents and discusses the following six questions to focus students' inquiry experiences: (1) What do you think will happen? (2) What actually happened? (3) How did it happen? (4) Why did this happen? (5) How can we find out which of these hypotheses is the most reasonable? (6) How can you relate the investigation to your daily life? (PR)

Describes the activities, goals, resource materials, and ways to participate in National Science and Technology Week. (MDH)

Describes the classification, number, and origin of wildflowers in North America. Discusses the use of a poster attached to the journal that includes activities to help students develop an awareness and appreciation of the native flora of North America. Additional activities are referred to in a list of 20 additional resources. (MDH)

Presents five hands-on activities that allow students to detect, measure, reduce, and eliminate moisture. Students make a humidity detector and a hygrometer, examine the effects of moisture on different substances, calculate the percent of water in a given food, and examine the absorption potential of different desiccants. (MDH)

Presents a protocol that can be used to discover that S. marcescens produces a bright red pigment when exposed to one temperature condition and does not produce this color under other conditions. Enables students to connect gene expression and environmental changes. (DDR)

Describes an experiment in which the density of solutions of known sugar concentrations is measured. Data are then used to determine sugar content in commercial beverages. (DDR)

Points out that the standard bell-jar model used to illustrate breathing has some features that may lead to a misunderstanding of the mechanism of ventilation. Proposes modifications to the model. (DDR)

Provides information on computer software using Geographic Information Systems (GIS) and visualization technologies and Visual Earth, a series of integrated classroom solutions for a variety of science topics. Describes some uses of GIS and Visual Earth in science classrooms. (ASK)

Presents an activity using computer software to investigate the role of the heart and blood, how the blood system responds to exercise, and how pulse rate is a good measure of physical condition. (ASK)

Draws data from student responses to the Science Laboratory Environment Inventory (SLEI) and a curriculum analysis of the implemented laboratory tasks. Involves biology, chemistry, and physics students (N=387) in 20 classes in Tasmania, Australia. Contains 23 references. (DDR)

Presents activities to stimulate the curiosity of grade 10-12 students and introduce them to astronomical observations. Exposes students to the evolutionary theory of stars and the structure of the universe. (DDR)

Describes three calculations used to make students aware of the size of Avogadro's number: (1) the new size of a 6-inch diameter ball with volume increased by a factor of Avogadro's number; (2) the number of moles of sand grains in the Sahara Desert; and (3) the dimensions and length of a mole of hydrogen atoms shaped into a cube, a square, and a…

Explains a way of observing pattern formation in the Blue Bottle chemistry demonstration by pouring a solution containing sodium hydroxide, glucose, and dye into a Petri dish and placing the dish on an overhead projector. (WRM)

Describes a program for bringing industrial applications of technology into high schools to enhance students' perceptions of the chemical industry and industrial careers in chemistry. Ambassadors from the Proctor and Gamble Company and Miami University--Middletown helped students work through a typical product-development cycle for fabricating…

Describes a series of exercises intended to help students develop a better understanding of chromatography that employ plant pigments. A collaborative approach leads students to a level of competence that permits them to complete an open-ended exercise. (WRM)
