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

A description of a field experience to demonstrate some basic principles concerning the geologic transport of beach sands. (Author/CP)

Introduces the pea plant experiment targeted to determine the effects of Knop's solution, a solution containing all the necessary minerals, on plant growth. Compares two groups of pea plants, one treated with Knop's solution and one treated with demineralized water. (YDS)

Describes several well documented cases of Extra Sensory Perception (ESP), and discusses ways in which ESP experiments can be conducted in the science classroom to investigate telepathy, pyschokinesis, and clairvoyance. (JR)

Briefly outlines the theoretical basis of the phenomenon of photoconductivity and describes a simple experiment which demonstrates the photoconductive properties of cadmium sulfide. (JR)

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

Several investigations can be undertaken with live sea anemones. A sea anemone's feeding response, fighting power, color, and symbiotic relationships to other invertebrates (such as a marine hermit crab) can be investigated in the high school classroom. Background information and laboratory procedures are provided. (Author/JN)

Presented is an activity in which students use a microscope to do a forensic hair comparative study and a medullary classification. Mounting methods, medulla types, hair photographs, and activities are described. (DS)

Describes a technique for the supercooling of water, for use in the science classroom, involving adding common salt to a mixture of ice and water. Several investigations are included for use during (and after) the process of supercooling. (DS)

Explores three classic turning points in science and presents close-up views of the scientists involved and their discoveries. Discussions include William Herschel and light; Lavoisier, Priestley, Scheele and oxygen; and Faraday and electromagnetism. Presents suggestions for experiments to demonstrate these discoveries. (JRH)

Describes a process to develop high school laboratory activities using intertidal ecology of the New England Coast as an example. (MKR)

Briefly describes the ecology of a deciduous forest, and suggests activities for observing and appreciating the changes that occur during the Fall. Simple experiments relating to mosses and lichens are outlined. (JR)
