Reports on a study that explored alternative ways of presenting chemistry in junior high schools through the use of an attitude survey taken by students (N=593). Analyzes and discusses student suggestions for curriculum, teaching strategies, and learning environments. Contains 15 references. (DDR)

Illustrates the development of multimedia courseware such as CHEMMAT. Discusses the features of the courseware including adaptability, use of the teacher module, use of graphics and video clips, and the ease of customizing the content in various languages. (DDR)

Reports and discusses observations of three confident, experienced teachers organizing investigative science in their classrooms. The teachers wore microphones and the recorded data coupled with field notes formed a record of what happened that could be negotiated with the teachers. (DDR)

Describes an activity in which students make milk solids separate from the milk. Provides background information, a series of questions that students should be asked as they approach and perform the activity, and ideas for extension projects. (DDR)

Describes an earth science unit in which students study soil from their own backyards through a series of integrated activities. Introduces several earth science concepts, including local geology and the development of different types of geological regions. Presents activities to make a county soil map, measure moisture in soil, and measure the…

Describes a science activity appropriate for middle and high school students investigating the temperature, pH, and conductivity of a man-made lake. Uses an inquiry-based interdisciplinary approach. Collects and analyzes data to determine whether there is any significant difference among the factors considering the very little variance in lake…

Presented are 10 intervention techniques for making science a hands-on experience for disabled students. Included are field trips, lab buddies, flexible rooms, customized lab equipment, lesson adaptation, precourse interviews, involving the class, computer-assisted learning, social considerations, and the team approach. (KR)

Discussed are the two sides to the question of laboratory dissections. Alternatives to dissection are proposed as well as the importance of incorporating dissections in a science curriculum. (KR)

Outlined is a specific computer application which can be used to analyze data on plant community composition from the point quarter sampling method. Procedures, examples of spreadsheets prepared in this manner, and evaluation of the activity are presented. (CW)

Presented is an experiment which demonstrates principles of experimental design, solubility, and crystal growth and structure. Materials, procedures and results are discussed. Suggestions for adapting this activity to the high school laboratory are provided. (CW)

Reviewed are six computer programs which may be useful in teaching college level chemistry. Topics include dynamic data storage in FORTRAN, "KC?DISCOVERER," pH of acids and bases, calculating percent boundary surfaces for orbitals, and laboratory interfacing with PT Nomograph for the Macintosh. (CW)

A paper model which is designed to give students a hands-on experience during lecture and blackboard instruction on DNA structure is provided. A list of materials, paper patterns, and procedures for using the models to teach DNA structure and replication are given. (CW)

The use of living animals in the classroom is discussed. A checklist of ideas to remember when considering housing animals in the classroom is provided. (CW)

Described is the use of the microcomputer and interfacing equipment to obtain weather data from meteorological satellites. Equipment necessary for this type of remote sensing, including constructing and/or obtaining the necessary hardware and software is discussed. Ideas for the integration of this material into the curriculum are presented. (CW)

Described is a simple test which uses micro- and macro-observations of onion root tips to demonstrate mutagenic and other toxic effects of various contaminants. Discussed are materials, methods, microscopic procedures, and applications of this activity. (CW)
