Listed are ways to demonstrate physical and chemical properties of matter and to show electrolysis using an overhead projector. (RH)

Uses charcoal briquettes, ammonia, water, table salt, and laundry bluing to create white fluffy crystals. Briquettes are placed in a bowl while the remaining ingredients are mixed together and poured over the briquettes. The result is white fluffy crystals forming on top of the charcoal. This experiment dramatizes chemical reactions to…

Describes a year long laboratory program for third, fourth, and fifth graders. States the goal of the program is to demonstrate what chemistry is, how it is done, and why it is fun and interesting. Provides a syllabus of the experiments and lists educational objectives. (MVL)

Discusses methodology for several activities which use Alka Seltzer tablets as a source of carbon dioxide gas. (CS)

Presents an approach that is used to introduce elementary and junior high students to a series of activities that will provide concrete experiences with acids, bases, and indicators. Provides instructions and listings of needed solutions and materials for developing this "magic sign" device. Includes background information and several…

This compilation of four journal articles (Instructor, September 1980; Science and Children, September 1980; and Science Teacher, September 1980 and March 1981) focuses on volcanoes, particularly Mount St. Helens in Oregon. The first article, "The Earth is Alive!" describes the eruptions of Mount St. Helens, provides basic information on…

"COMETS on Careers" describes science-related careers, introduces activities illustrating a science concept being studied, and encourages use of professional persons as activity leaders. Several COMETS chemistry activities are described. These activities, which can be performed in school or at home, focus on colloids, acid/base…

This document contains 395 abstracts of presentations on the theme of changing the image of chemistry, made at a conference on chemical education. Included with the abstracts are the presenters' names and addresses. The conference included the following sessions: Lecture and Learning: Are They Compatible?; ChemSource; Relevant Chemistry for the…

The concept of a chemical reaction (as opposed to physical mixing, dissolution, or change of state) is developed in this five-part unit. In addition, the ideas that chemical reactions involve the formation of new substances and that mass is conserved in a chemical reaction are stressed. Part 1 discusses unit objectives and considers teachers'…

Cites studies related to students' misconceptions about the particulate nature of matter. Stresses that a good understanding of these concepts is fundamental to the study of chemistry itself. Reports on a study of preservice elementary teachers views of the particulate nature of matter before instruction on the topic. (TW)

Stresses the value of encouraging students to question the results of both obvious and the less obvious scientific activities. A simple science activity built on chemical reactions. (EB)

Discusses development and presentation of a chemical demonstration show for grades 1-6 students. Includes major concepts presented and experiments used in the hour-long show. Concepts/experiments focus on the show's theme: the nature of chemical change. Safety factors involved when conducting demonstrations with children are addressed. (JN)

This unit consists of four parts. Part 1 contains a five-item instrument designed to help teachers clarify their own views about "burning." Part 2 discusses scientists' views about burning and lists answers to the survey instrument presented in part 1. Part 3 contrasts scientists' views with children's views, using children's comments…

Describes three teaching activities used in the Chemistry for Kids program which focus on how esters are chemicals partially responsible for the flavor of foods. Includes a discussion of a demonstration involving role-playing, a set of taste tests, and an activity using chewing gum to investigate odors in food. (TW)

Presented is a science activities in energy package which includes 15 activities relating to chemical energy. Activities are simple, concrete experiments for fourth, fifth and sixth grades which illustrate principles and problems relating to energy. Each activity is outlined on a single card which is introduced by a question. A teacher's…
