Directions are given for student learning activities on illusions, shadows, the spectrum, and colors. (DT)

Presents three experiments exploring aspects of the greenhouse effect. Topics and discussion includes radiation in energy transfer, emissivity and absorptivity, the irrelevance of reflectivity, a digression on insulators and convection, climate change, and radiative energy balance. (MCO)

Presents a series of investigations focusing on the biodegradable packing materials ("peanuts"), which provide a method for exploring science through experimentation. These activities can help fourth through sixth graders sharpen their critical thinking and science process skills. (PR)

Twelve science activities involving the common paper food bag and the small plastic food bag are described. (DT)

A seventh-grade botany project involving experiments with beans is described. (DT)

Directions are given for the construction of a manometer to measure animal metabolism. Steps in an experiment to measure frog metabolism are specified. (DT)

Describes activities with organisms from freshwater ponds and ditches. Several experiments involve predation, some involve habitat choices, and one addressees the role of sunlight in supporting plant-eating animals. (PR)

Presents two experiments about ozone related topics. The first experiment examines the effect of sunlight on newsprint and relates this to human skin. The second demonstrates how chemicals, and specifically chlorofluorocarbons travel through the air. (MCO)

A joint business-chemistry course which focuses on consumer testing is described. Guidelines for organizing the students into testing teams and suggested laboratory experiments are included. (DT)

Explains the advantages of having students write research proposals before conducting experiments for science fairs. Describes what should be in the research proposal. (PR)

Describes an experiment where elementary students determine the optimum angle of inclination for the greatest amount of distance a marble will roll when accelerated down an inclined plane. (PR)

Presents an activity in which students make a simulated solar panel to learn about the principles behind energy production using solar panels. Provides information about how solar panels function to produce energy. (MCO)

A shoe box is converted into a model home to demonstrate the energy efficiency of various insulation measures. Included are instructions for constructing the model home from a shoe box, insulating the shoe box, several activities involving different insulation measures, extensions of the experiment, and post-lab discussion topics.
