Suggests using funnels and tunnels in combination with water, blocks, transportation toys, and other materials to help teach preschoolers to make predictions. Many examples are included for using funnels to understand properties of liquids and for using tunnels to predict order. (DH)

Describes a laboratory activity on plate tectonics which focuses on the connection between plate tectonics and the different types of volcanoes. Provides questions for discussion and includes suggestions for extending the activity. (ML)

Using the problem of trash disposal as an example, students participate in science activities designed to develop the following science skills: classifying, observing, measuring, communicating, inferring, and predicting. Activities are described in detail and a reproducible page is provided. (JL)

Using ordinary household items--vinegar, ammonia, and cabbage juice--teachers can demonstrate properties of acids, bases, and neutrals. Students are encouraged to discuss results and hypothesize about experiments. A guide to the project is provided. (JL)

Describes a simple way of obtaining a set of relative intensities of spin-spin splitting lines using Pascal's triangle rather than calculating binomial coefficients. Provides tables showing Pascal's triangle and the relative intensities of multiplets for a range of nuclear spins. (TW)

Described are experiments to give students experience in the synthesis of peptides from amino acids and to use visible spectroscopy to measure a rate of reaction. The activities were designed for undergraduate courses. (RH)

Presents a three-part exercise which provides undergraduates with opportunities to work with data related to the earth's magnetic field. Includes student materials for activities in determining the history of the earth's magnetic field, in finding the general pattern of declination, and for looking for a polar reversal history. (ML)

Presents information that gives a methodological background to the concept of food webs. Stresses the importance of calibrated techniques in ecological research and explains direct methods for studying animal diets. Exercises for gathering first-hand data on bird diets and analyzing secondary data on mammal diets are suggested. (ML)

Discussed are the basic and specialized skills needed for graphing exercises. Suggests approaches and activities that can be used in the teaching of graphing skills. Includes a listing of software programs for both teaching graphing and for analyzing data. (ML)

Describes a procedure for oxygen generation by thermal decomposition of potassium chlorate in presence of manganese dioxide, reacted with various sulfides. Provides a table of sample product yields for various sulfides. (JM)

Presents activity ideas for using insects in art and craft projects. Each activity includes recommended age level(s), list of materials needed, and procedures. Although geared for art, the activities can be used to complement activities in science, mathematics, and other subjects. (JN)

Presents (1) background information explaining how paleontologists solve dinosaur mysteries using fossil clues; (2) activities on this topic; and (3) ready-to-copy student materials. Each activity includes an objective, list of materials needed, recommended age level(s), subject area(s), and instructional strategies. (JN)

Presents lists of materials needed and procedures to make foggy scenes with wax paper; create snowflake patterns with cut straws; and make a wind sock to record wind speed/direction. Although geared for arts and crafts, the activities can be used to complement activities in science or other subjects. (JN)

List of materials needed and procedures are provided for (1) making wobbly bird figures out of plastic pantyhose eggs; and (2) making parrot puppets out of household items. Although geared for art, the activities can be used to complement activities in science or other subjects. (JN)

List of materials needed and procedures are provided for (1) making earth paintings from soil-made paint and (2) making a paper-mache giant saguaro cactus. Although geared for art, the activities can be used to complement activities in science or other subjects. (DH)
