An activity is presented in which the thermodynamics of simultaneous, consecutive equilibria are explored. The activity is appropriate for second-year high school or AP chemistry. Students discover that a reactant-favored (entropy-diminishing or endergonic) reaction can be caused to happen if it is coupled with a product-favored reaction of…

The three step synthesis is presented to allow the functionalization of an aromatic amine by forming new C-C and C-N bonds via an intramolecular C-H activation under mild conditions. The reactions are stoichiometric and allow the students to isolate the different organometallic intermediates.

Note is presented on the standard lab from a second year chemistry course. The lab "Determining which of the Seven FD&C Food-Approved Dyes are Used in Making Green Skittles", familiarizes students with the operation of the CHEM2000 UV-Vis spectrophorometer.

A circuit board analysis of the atomic absorption spectroscopy, which is used to measure lead content in a course for nonscience majors, is being presented. The experiment can also be used to explain the potential environmental hazards of unsafe disposal of various used electronic equipments.

A laboratory experiment that provides students a hands-on introduction to the specific techniques of liquid chromatography-tandem mass spectrometry (LC-MS/MS) and electrospray ionization is presented. The students can thus practice the analytical principles of sample extraction, detection, quantification, and quality control using a fresh fish…

The community can be a powerful context and mini-laboratory for cultivating students' common understandings of science and mathematics. On the island of Panay in the Philippines, the community was the starting place for a group of fifth- and sixth-grade students to explore simple machines in their daily lives. What students learned in the process…

This book is part of the series "Explorations in Science" which contains enrichment activities for the general science curriculum. Each book in the series contains innovative and traditional projects for both the bright and average, the self-motivated, and those who find activity motivating. Each activity is self-contained and provides everything…

Learning about science needs to be active, collaborative, and connected to the everyday personal lives of children. This book is a collection of humorous conversations, pictures, and activities designed to help children understand how and why changes happen in the world. The focus is on personal experience and how models are developed, how one can…

This document provides biology experiments designed for students who have completed a first year biology course. This self contained laboratory booklet contains four sections. In section 1, "Instrumentation in the Study of Cells," discussion sections and suggestions for teacher demonstrations are provided. It also includes some basic materials…

This book contains 101 investigations for chemistry classrooms. Topics include: (1) Physical Properties; (2) Reactions of Some Elements; (3) Reactions Involving Gases; (4) Energy Changes; (5) Solutions and Solubility; (6) Transition Metals and Complex Ions; (7) Kinetics and Equilibrium; (8) Acids and Bases; (9) Oxidation-Reduction; (10)…

The purpose of the index is to guide students in finding information on thousands of science experiments for investigative projects and science projects for science fairs. Experiments range from simple to complex and are from 1527 books that are both old and new. The nature and range of the projects and activities are appropriate for primary…

This book contains simple experiments and projects through which students can learn about water and its properties. Some of the topics discussed include acid rain, dehydration, distillation, electrons, tidal waves, and the water cycle. Experiments include: finding out about the amount of water in the body; why there is water in the body; how to…

In investigative work, pupils encounter relatively open-ended tasks for which they have to devise their own solutions. Historically, the development of investigative work in the United Kingdom has come to the point where many schools are adopting it with some enthusiasm and with a degree of success. Progression has been largely defined by the…

Presents the results of an experiment designed to test two hypotheses: (1) a delay of two weeks at room temperature will have no effect on the viability of fertile chicken eggs and (2) refrigeration will have no effect on the viability of fertile chicken eggs. Experimenters were the author and two ninth-grade students. (PEB)
