The authors of this curriculum supplement believe in a laboratory approach to chemistry and express the feeling that environmental chemistry provides the students an opportunity to apply theoretical chemistry to important practical problems. There are eighteen activities presented, each accompanied with behavioral objectives, one or more suggested…

This course guide is the fifth in a series dealing with chemistry. The course is specifically designed for students interested in taking the Advanced Placement Chemistry examination and thus is equivalent to a first year college general chemistry course. Included in the guide are performance objectives, visual aids, a course outline, a list of…

This science study aid, produced by the U.S. Department of Agriculture, includes a series of plant rooting activities for secondary science classes. The material in the pamphlet is written for students and includes background information on plant hormones, a vocabulary list, and five learning activities. Objectives, needed materials, and…

Described is a qualitative analysis laboratory procedure for high school chemistry students. The paper received the Science Teaching Achievement Recognition (STAR) award. The procedure acquaints students with certain ions and uses the knowledge of ions to devise a flow-chart for separating and identifying these ions in an unknown solution. (SL)

Presented is a science activity in which the student investigates methods of calibration of a simple conductivity meter via a hands-on inquiry technique. Conductivity is mathematically compared to salinity using a point slope formula and graphical techniques. Sample solutions of unknown salinity are provided so that the students can sharpen their…

This publication is intended to aid in the planning and implementation of Advanced Placement (AP) chemistry courses. Included are reports from high schools that have established such courses concerning costs, facilities, and instructional requirements. Also included are the free-response sections of the 1974 and 1975 AP Chemistry Examination,…

Provided are directions for culturing bacteria by using yoghurt as a culture medium. Yoghurt is a safe medium and results in an end product which may be eaten if desired. (PB)

Presents an alternative approach to teaching Systematic Transition Metal Chemistry with the transition metal chemistry skeleton features of interest. The "skeleton" is intended as a guide to predicting the chemistry of a selected compound. (Author/SA)

Described is the subject of biological scaling for physics teachers including examples and in-depth reading. Topics are elements of scaling, terminal velocities, Lilliputian and Brobdingnagian, brain evolution, dolphin echolocation, surface tension, gravity change, food and oxygen, and seeing. Ten references on physics and size, and ten questions…

Author argues that the only way to move science education progressively forward is by teachers respecting the pedagogical research reports. Asserts that only a research-based rationale for teaching science separates the professional science teacher from those who simply have a strong science background. Urges authors and editors to present…

An exciting laboratory environment is activated by the preparation and novel use of magnetic materials to decontaminate water through adsorption and magnetic removal of metals and organics. This uncomplicated technique is also adaptable to the possible application of adsorbents to numerous other environmental substances.

Information about the diploma examinations in Mathematics 30, Biology 30, Chemistry 30, and Physics 30 that will be administered during January, June, and August, 1987, is provided in this bulletin. Topics explained include: (1) general format of the examination (stating the content, emphasis, and time allotments for the examinations); (2)…

This guide is a result of two years' piloting and revising the Science Curriculum Improvement Study (SCIS) program for the students of Guam. The life science portions of SCIS were chosen and adapted for the ecology of the area. Program flexibility is stressed and outdoor activities are encouraged. Used in grade one, the topic of organisms is…

Contained in this package are two pieces of literature related to the Australian Science Education Project: A Guide to ASEP/Introduction to ASEP (leader edition) and A Guide to ASEP/ASEP Units and Their Use. The Guide to ASEP is a set of teacher education materials designed for use by teachers and others who wish to learn about the Australian…

These guidelines are designed to help Maryland's educators and citizens make informed choices about the types of facilities they will provide for teaching science in grades K-12. They are not a blueprint for facilities nor are they an attempt to standardize all science programs or facilities, but seek to identify elements to consider, people to…
