Presents an activity in which students investigate the formation of solid ammonium chloride aerosol particles to help students better understand the concept of acid rain. Provides activity objectives, procedures, sample data, clean-up instructions, and questions and answers to help interpret the data. (MDH)

Argues that student field trips should provide students with learning experiences rather than entertainment. Gives examples of science demonstrations that engage the student in the scientific process using hands-on experiences. (MDH)

Presents background information, science activities, and a color poster on the element chlorine. (PR)

Describes interdisciplinary activities for teaching students accurate information about dinosaurs. A list of 20 resources is provided. (PR)

Describes ScienceFest, a program that teams up students and teachers in an effort to create and perform original science-related plays. (PR)

Discusses four elements of cooperative learning in science classrooms: cooperative task structures; cooperative incentive structures; individual accountability; and heterogeneous grouping. Presents and describes seven cooperative learning methods. (MDH)

Describes a one-week, cooperative-learning assignment in which students design their own space stations. (PR)

Describes the use of Vee maps in helping students understand scientific investigations. (PR)

Presents an activity in which students in grades 5-8 learn about snail reproduction by observing and charting the activities of land snails, freshwater snails, and slugs. Instructions to implement and extend the activity are provided. (MDH)

Describes two curriculum approaches used at a college as an alternative to traditional introductory science-survey courses. The first course is entitled "Nature of Science" and the second is "Current Research." (PR)

Describes an activity to simulate the geometries of a spreading pathogen such as HIV throughout a generation. Students exchange "bodily fluids" three times and are then tested for the presence of "infection." Materials used include base solutions (NaOH or KOH), phenolphthalein (pH indicator), clear plastic cups, and an eye dropper. (PR)

Describes an easy and inexpensive method of preparing experimental growth media that high school students can use for plant cloning investigations. (PR)

Describes enrichment activities in which students read selections from science trade books and perform hands-on science activities related to the readings. Suggests four readings and related activities involving trees, robots, spiders, and birds. (Contains 13 references.) (MDH)
