Research shows that that children learn science and engineering subjects best by engaging from an early age in the kinds of practices used by real scientists and engineers. By doing science and engineering, children not only develop and refine their understanding of the core ideas and crosscutting concepts of these disciplines, but can also be…

A systems thinking approach to incorporating green chemistry and safety into laboratory culture is vital, as chemists will be at the molecular level of the innovative solutions to our global challenges. Training chemists to have the skills and culture to accomplish this feat in the safest way possible is pivotal to safe working conditions within…

The COVID-19 pandemic is resulting in widespread and ongoing changes to how the K-12 education system functions, including disruptions to science teaching and learning environments. Students and teachers are all figuring out how to do schooling differently, and districts and states are working overtime to reimagine systems and processes. This is…

Science starts at home. Parents play a crucial role in determining how much science their children learn. This paper presents a list of tips that parents can use to help their children learn science. They are: (1) Focus on your child's interests; (2) Talk with your child about what you are doing-- make it a two-way conversation; (3) Girls are just…

Instead of piling on one new reform fad after another, here at last is a book that boils down solutions for improved schools to the most powerful, simple actions and structures that ensure you prepare all students for college, careers, and citizenship. Best-selling ASCD (Association for Supervision and Curriculum Development) author and renowned…

Classical phenylketonuria (PKU) is caused by a lack activity in the enzyme phenylalanine hydroxylase, leading to elevated concentrations of phenylalanine in the blood. A simple demonstration and three advanced demonstrations of a spot test for phenylpyruvic acid and its relationship to phenylketonuria are given.

This science unit focuses on measuring skills using students' own sneakers and the unit of measure. Two activities with differing levels of difficulty are presented. (MT)

A classroom exercise that engages students as a team to develop an intuitive understanding of P-V-T phase behavior of a pure fluid is discussed. This exercise, when implemented in classrooms over a period of three years revealed that the students achieved a deeper level of understanding about phase behavior.

An upper-level undergraduate experiment that, in addition to introducing students to catalysis using an air sensitive transition-metal complex, introduces the use of a solid acid as an activator and support for the catalyst is developed. The increased stability acquired in the course of the process affords the opportunity to characterize the…

Presents the plans for constructing a mode 2 TOPS Projector-adaptor, which costs one-half that of a model described in an earlier article. The author uses a step-by-step approach to the project. (SA)

This model is useful in identifying specific learning problems and in providing techniques for the teacher to motivate and teach students at all levels. What it is and how it can be used are discussed, illustrated by specific strategies for geometry and science. (MNS)

Lists 46 household chemicals readily available at local stores by common name, chemical name, chemical formula, and typical commercial source. Suggests that school budgetary constraints can be eased by this practice and that students can become more chemically literate as consumers. (JJK)

A comprehensive program in the field of green chemistry, which concentrates on processing and managing of wastes produced during laboratory experiments, is presented. The primary aim of the program is to instill a sense of responsibility and a concern for the environment through organic chemistry education.

An exercise that provides a hands-on demonstration of the hydrolysis of aspirin is presented. The key to understanding the hydrolysis is recognizing that all six process may occur simultaneously and that the observed rate constant is the sum of the rate constants that one rate constant dominates the overall process.

The measurement of the infrared rotation-vibration spectrum of HCl(g) is a common experiment in the physical chemistry laboratory, which allows students the opportunity to explore quantization of rotational states in diatomic molecules. It is found that the CO2 vibration-rotation spectrum if used as an addition to the HCl experiment would give the…
