Presents abstracts of innovative activities of students in grades 7 through 12. Projects include community surveys, student or teacher initiated home/school experiments, scientist-supervised research by high school students, community and school service projects. (EB)

Provides a listing of articles and papers published in 1976 relating to various fields of biology and presents various biological science activities. (SL)

Two instruments are described which were designed to provide beginning students with the tools for determining sun-time and the altitude of the sun. Both can be constructed by the student. A simple-to-construct scale is included. Activities are suggested to use with the instruments. (Author/EB)

Provides eight physics experiments, demonstrations, and activities relating to radioactive decay, computers, semiconductors, and electronics. (SL)

In this exercise, students examine Aristotle's weight hypothesis by testing variously shaped marble chips. These chips are weighed and dropped down a water tube. Average fall times and weights are recorded and graphed. Students are asked to apply this information to rock and soil deposition by streams. (MA)

Several suggestions are given related to the use of student-collected rocks in gaining understandings basic to the later mastery of concepts and principles of geology. Ideas related to language development, classification schemes, observation skills are suggested. (EB)

A description of four rapid tests to determine the viability of stored seeds are given. Typical results are reported and some possible applications of the tests are discussed. (Author/EB)

Outlined are 10 experiments, demonstrations, and helpful hints for elementary science classes utilizing common, inexpensive materials. Topics include mixing colored lights, detergents, weightlessness, solar energy, and hydrogen gas. (SL)

Discusses activities with magnets and magnetism for elementary students. (SL)

Reviews articles and papers published in 1975 relating to chemistry and presents a number of chemistry experiments, demonstrations,and activities. (SL)

Described are five physics experiments utilizing inexpensive, readily available materials or materials normally found in a physics laboratory. Included are investigations of electrical charge, sound detection, thermal expansion, doppler effects, and the cycloid. (SL)

Describes an earth science laboratory approach designed to involve students in an ongoing method of solving problems; student questions and discussion provide the basis for laboratory exercises. (Author/SL)

Described is an approach for teaching the concept of mass to elementary students. A method for making simple balances and weight sets is also given. (MR)

Describes five experiments that are done with eggs, including one on osmosis, and an experiment on gyroscopics. (BR)
