Concepts to be developed, objectives, and student instructions are provided for an activity useful as an introduction to or review of Mendelian genetics and sex determination. Universal codes (read by optical scanners at supermarket checkout stands) from soup can labels are used as chromosome maps during the activity. (JN)

The author suggests activities about simple food chains as a way of teaching elementary students concepts of energy needs, energy consumption, and energy transfer. (SJL)

The Animal Awareness club is designed to make humane education an integral part of the classroom. Reported is the format, evaluation, and follow-up materials for an animal awareness club. (Author/DS)

Suggests some nonfiction children's books and learning activities for the study of astronomy in the primary and upper elementary grades. (SJL)

Polyelectrolytes are discussed with regard to their importance to the undergraduate science major enrolled in a physical chemistry course. Suggests the importance of the solution behavior of polyelectrolytes to scientific disciplines and many industries. (Author/SA)

Provides ideas for involving fathers in a day care center along with samples of activities and experiments in science and mathematics and in a "Science and Math Fair." (MP)

The zonation of plants within a salt marsh environment is detailed via illustrations and scientific nomeclature for purposes of encouraging outdoor educators to use the salt marsh environment as a learning laboratory. (JC)

Discusses the principles behind holograms: the design and procedure to make either a reflection hologram or a transmission hologram, developing the hologram, safety precautions, and classroom applications. (JRH)

Provides a general description of chemiluminescence and distinguishes between the two types of chemistry that contribute to our understanding of chemiluminescence: fluorescence and the excitation process. Presents an activity that explores the phenomenon. (DDR)

Describes an activity in which students assume the roles of scientists living in the year 2,001,997 and make their own fossil record discoveries of animals that have undergone evolutionary changes since 1997. Students choose the animals as well as create the adaptations that have taken place. Includes a sample scoring rubric. (DKM)

Presents a project that allows students to observe and show how quickly pollutants in the air and on the ground destroy plant life. Appropriate for grades four through six. (JRH)

Describes a DNA fingerprinting simulation that uses vegetable food coloring and plastic food containers instead of DNA and expensive gel electrophoresis chambers. Allows students to decipher unknown combinations of dyes in a method similar to that used to decipher samples of DNA in DNA fingerprint techniques. (JRH)
