The purpose of this article is to outline some of the characteristics of children's notions of physical causality and to relate this to how one might expect the typical five-year-old, eight-year-old, and twelve-year-old to approach a problem in science. (Author)

The "thorough and efficient" science program must involve all students with their minds and their hands in science activities that make sense to them. (Editor)

A description is given of a class project concerned with examining a population problem and making some political decisions to solve it. A list of topics for the students to research as a basis for their decisions is provided. (DT)

Describes a technique for imparting essentially the same speed, in opposite directions, to two gliders to demonstrate that total momentum of equal masses traveling at the same speed in opposite directions is zero. Also describes a technique using a compression spring and beeswax for momentarily holding two gliders together prior to starting them…

Describes an undergraduate laboratory project involving lecithin which integrates two general aspects of lipid methodology: chromatographic techniques and use of enzymes specificity to obtain structural information. (Author/SLH)

Discusses the offering of a one-week "fun" lab course designed for students to further their professional competence, offer intellectual enrichment, advance their avocational interests, or provide personal enjoyment. (CC)

Included in this publication for parents and teachers are over 30 anecdotes that serve as suggestions for varied science activities for young people. The first section presents the objectives and organizing the learning environment. The second section presents a variety of ways to help children explore their environment. The last section suggests…

Describes an unusual learning experience available to eighth-grade students in Louisiana through exposure to a World War II B-25 simulator. The flight simulator is used to motivate students in the science area, develop an awareness of flight problems and challenges and provide exposure to the electronics career field. (BR)

Describes the use of laboratory experiments termed hands-on demonstrations that are designed to reinforce the concepts covered in lecture with emphasis on maximizing the sense content (sight, smell, hearing) to improve retention by the student. (GS)

Describes how to use playing cards as simulators to demonstrate several aspects of allelism and allele frequency in a gene pool. They provide an "unexpected" result, promote group discussion and may stimulate students to devise variations for comparison. (BR)

You can't see, smell or taste air - but here's an easy method for experimenting with it. (Editor)
