Background information, apparatus needed, procedures used, and results obtained are provided for a simple kinetic method for the monitoring of adsorption processes. The method, which involved adsorption of crystal violet onto activated carbon, is suitable for classroom and/or research purposes. (JN)

Describes relatively simple nuclear magnetic resonance (NMR) experiments that demonstrate unexpected results of the deceptively simple and deceptively complex types. Background information, experimental procedures, and typical results obtained are included. (JN)

Describes a simple procedure for carrying out ultra-micro boiling point determination, presenting typical results obtained. Advantages of using the procedures are noted. (JN)

Background information, procedures used, and typical results obtained are provided for experiments involving the nitrile oxide cycloaddition with enamines. The experiment is suitable for advanced undergraduate organic laboratories or beginning undergraduate research. (JN)

Describes six demonstrations used in a medical biochemistry course. These demonstrations focus on: (1) platelet aggregometry; (2) ion-transporting antibiotics; (3) glycosylated hemoglobin; (4) molecular models; (5) serum preparation; and (6) bioluminescence. (JN)

Shows how the use of pulleys can add a new direction to experiments that demonstrate forces. Procedures used and typical student results are included. (JN)

Background information, list of required materials, and procedures are provided for an immunological assay which has been modified for use as a classroom/laboratory demonstration of antigen-antibody reaction. The assay is designed for a two and one-half hour laboratory period but may be modified for one hour laboratories. (JN)

Discusses a laboratory exercise (suitable for the day before spring vacation) involving use of a hard-boiled egg to stimulate student responses to questions on the effect of adding salt to the water, formation of iron sulfide, ease of peeling, and gas laws. Additional experiments are included. (BC)

The separation of lead and bismuth by chelate solvent extraction is of interest because of the simplicity which the use of radiotracers allows in its demonstration. Theoretical background information, procedures, materials needed, and typical results are provided for an experiment involving the extraction. (JN)

Although the Einstein-Podolsky-Rosen experiment was originally a hypothetical situation, John Bell was able to apply a version of their argument to an experiment that could actually be done. This experiment (called "Bell's Inequality") and a hypothetical experiment analogous to the one Bell proposed at the atomic level are described. (JN)

Procedures for two demonstrations are presented. The first is a demonstration of chemiluminescence. The second is a demonstration using a secondary battery constructed from common household articles. (JN)

Describes a procedurally quick, simple, and inexpensive experiment which illustrates the magnitude and some effects of solvent-ion interactions in aqueous solutions. Theoretical information, procedures, and examples of temperature, volume and hydration number calculations are provided. (JN)

This book presents science activities developed by teachers for children ages 3-6 years old. The activities aim to develop science skills including communication, observation, estimation, measurement, cause and effect, investigation, and evaluation in children by using their curiosity as a staring point. Activities include age suggestions, address…
