This study revamps and optimizes the teaching and learning process and instrument for the classic binary vapor-liquid equilibrium experiment by combining activity coefficient model simulations and practical exercises. Our teaching process combines a software simulation and practical exercises. Utilizing Aspen software, students can predict phase…

The author has successfully used a learning activity titled "The Year I Was Born" to motivate students to conduct historical research and present key scientific discoveries from their birth year. The activity promotes writing, helps students enhance their scientific literacy, and also improves their attitude toward the learning of science. As one…

The use of invertebrates as classroom "pets" can develop students' skills in scientific inquiry and instill respect for science. Few materials are needed for projects involving invertebrates. Suggested activities using snails, crickets, earthworms, crayfish, and guppies are offered. (DF)

Presents part of a new series aimed at providing exploratory activities for preschool children as they seek to become acquainted with the world in which they live. (Author/EB)

Describes exploratory activities for a young child seeking to become acquainted with the world in which he lives. (EB)

Describes an inquiry investigation to enable students to understand water cohesion, surface tension, and heating curves for water. The investigation includes several activities organized in a three-phase learning cycle: (1) exploration; (2) concept invention; and (3) concept application. (DDR)

Reviews the research regarding the use of laboratories in the teaching of science. Discusses the traditional process skills and adaptations of the learning cycle. Describes the four distinct characteristics of a Guided Inquiry Laboratory. Thirty-seven references are listed. (CW)

Intended to aid teachers help students discover the concept of human beings interrelating and interdependent with their environment. A science activity used with sixth grade students involved in a functional recycling system for newspapers is described. The program grew into a community-wide project, incorporated with city council. (EB)

Experiments with adapted apparatus which allow blind children to discover principles are described. Individualized experiences, specifically designed, are developed in four curricula and a sample lesson is presented. (EB)

Describes an open-ended, inquiry-based chemistry lab in which students design and construct snow globes. Encourages the development of problem solving skills. (DDR)

Some ways in which exploratory activities of the preschool child involve science concepts are described. The role of adults knowledgeable about both science and child development is stressed. Emphasis is placed on hands-on experiences. (EB)

Hands-on experiences are encouraged and some examples given to promote discovery learning for the very young. (EB)

Reports on a study that explored the types of questions that students ask for open-ended science investigations. Discusses how teachers can help students identify problems and pose questions that are feasible for investigation. (Contains 55 references.) (DDR)

Demonstrations are presented in which children can be introduced to evidence of specific concepts enabling them to participate in such a way that any conceptual conflicts that might arise in this learning situation can be gradually reduced. (EB)

Discussed is the teaching method called the learning cycle and how it can be incorporated into science activities. Included are examples of how teachers and students can use the learning cycle to produce instructional materials. (KR)
