Describes experiments that can be carried out by freshmen in general science courses. All experiments are prepared with inexpensive equipment and materials. Quantitative data are analyzed intuitively using graphical representations. (JP)

Simple laboratory investigations are given which expose elementary students to optical crystallography techniques. Procedures and materials are designed for sixth-grade students. (SA)

Describes an elementary school science activity in which students conduct experiments to verify their hypotheses relating to the effect of salt and other chemicals on the melting point on ice. (JR)

Describes an experiment, conducted by sixth-grade students, with mice that demonstrates the importance of a balanced diet. (JR)

Reexamines an experiment in which the volumetric fraction of oxygen in air was supposed to have been determined. Presents challenges to the procedure. (DDR)

A multidiscovery, open-ended, sciencing experience appears to have implemented nearly the full spectrum of cognitive, affective, and psychomotor objective domains.'' (Author/DF)

Simple activities are described which use paper clips and straws or a board to demonstrate the properties of the lever. (BB)

Describes a few activities designed to give students an opportunity to investigate man-made meteorites.'' (Author/DF)

This booklet was written for students as a source of ideas for research type science projects. Part One shows how three high school students developed individual projects a s a result of asking questions about the same natural phenomena. Part Two contains project suggestions and sample questions designed to stimulate student thinking along…
