Outlines a lesson plan/strategy for making use of the space shuttle model in the elementary science classroom. (DS)

Suggests using plastic bags as aquaria and terraria. Describes techniques for converting plastic sheets into aquaria, how to set them up for classroom use, and other uses for plastic bag aquaria. (DS)

Describes four activities for the elementary science classroom to help students develop their powers of description, explanation, and prediction. Topics of the activities are spool "gears," crystal comparisons, yeast magic, and clay cargo carriers. (DS)

Describes a laboratory exercise to demonstrate enzyme activity using gelatin and meat tenderizer. The exercise is adaptable to any grade level. (MA)

Suggests ways to organize successful science clubs for elementary school children. (CS)

Provides instructions for setting up an indoor pond for the elementary school classroom. (CS)

Describes concrete laboratory manipulations in which time and its measurement are studied while investigating the parameters affecting the functioning of a pendulum. Also describes the origin of pendula and how cultural and historical references are integrated into laboratory practice. (Author/JN)

An experiment is described relating activities with pendulums to the process skill of controlling variables. Includes materials needed, directions, and follow-up questions for the experiments. Lists five other experiments which could be used to teach the control of variables. (DS)

This is the first of a series of three seasonal environmental learning stations that create a land lab on the school grounds. This article describes the construction of a 10-station nature trail and the related student activities for grade levels 1 through 6. (Editor/SJL)

Describes an experiment to measure the thermal conductivity of some gases in an undergraduate physics laboratory using a hot wire method in the pressure range ten to one torr. (HM)

Presents excerpts from a teacher's manual which describes laboratory activities in genetics for advanced secondary school biology students. Maximized are the pedagogical aspects in choosing activities, arriving at intermediate decision-points, and planning the evaluation of pupil achievement. (CS)

Describes the infrared analysis of geological specimens which can form the basis of a laboratory exercise, allowing some minerals to be identified by "fingerprint" technique. Students can gain insight into the concept of symmetry and environment around an atom. (Author/SA)

Through a description of some of the activities which take place in his science classroom, the author makes a strong case for the inclusion of technology, or applied science, rather than pure science in the primary curriculum. (KC)

Presents 26 composition activities that offer elementary students an opportunity to practice expository writing through the preparation of short written or oral reports on scientific topics. (SJL)

Provides guidelines prepared by the National Science Teachers Association for the use and care of invertebrate and vertebrate animals in the classroom. Suggestions are made for conducting experimental and observational studies. (CS)
