The Cambridge IGCSE (R) Combined and Co-ordinated Sciences series is tailored to the 0653 and 0654 syllabuses for first examination in 2019, and all components of the series are endorsed by Cambridge International Examinations. This Chemistry Workbook is tailored to the Cambridge IGCSE (R) Combined Science 0653 and Co-ordinated Sciences 0654 syllabuses for first examination in 2019 and is endorsed for learner support by Cambridge International Examinations. Covering both the Core and the Supplement material, this workbook contains exercises arranged in the same order as the coursebook and are clearly marked according to the syllabus they cover. Developing students' scientific skills, these exercises are complemented by self-assessment checklists to help them evaluate their work as they go. Answers are provided at the back of the book.

Educating the next generation of chemists about green chemistry issues, such as waste minimisation and clean synthesis, is vital for environmental sustainability. This book enables green issues to be taught from the underlying principles of all chemistry courses rather than in isolation. Chapters contributed by green chemistry experts from across the globe, with experience in teaching at different academic levels, provide a coherent overview of possible approaches to incorporate green chemistry into existing curriculums. Split into three sections, the book first introduces sustainability and green chemistry education , before focussing on high school green chemistry education initiatives and green chemistry education at undergraduate and post-graduate levels. Useful laboratory experiments and in-class activities to aid teaching are included. This book is a valuable resource for chemical educators worldwide who wish to integrate green chemistry into chemical education in a systematic and holistic way. It is also of interest to anyone wanting to learn more about the different approaches adopted around the world in sustainability education.

This unique book of real chemistry and science for children illustrates the nature of physical and chemical change using the very smallest parts of things: atoms and molecules. It encourages children, ages 5-12, along with their parents or teachers, to become active learners of science, to discover meaning not only in the ideas and definitions of others, but also (and especially) in their own world. Chapters include: Evaporating, Condensing, Dissolving, Crystallizing, Mixing, Separating, Melting, Freezing, and Reacting.

The 21 Super Simple Chemistry Experiments workbook presents the steps of scientific investigation individually in separate experiments so students can focus on one aspect of scientific inquiry at a time. Students will learn how to make good observations, build models, and evaluate data. Each experiment is simple and easy to do and will help students develop the skills they need for real science investigations. Each experiment has a one page description with minimal setup and materials.

MOLECULES and the Chemical Bond is about understanding Schrodinger s equation, for chemical systems.

In his famous Lectures on Physics, Richard Feynman quotes Paul Dirac on what it means to understand an equation. I understand what an equation means, said Dirac, if I have a way of figuring out the characteristics of its solutions without actually solving it. That hits the nail on the head It s precisely what Conceptual Valence Bond Theory does for Schrodinger s equation.

A physical understanding of an equation, adds Feynman, is a completely unmathematical, imprecise, and inexact thing, but absolutely necessary for a physicist. It unfolds in MCB in two stages, described by Newton as a stage of Analysis (a union of observations and inductions) and a stage of Synthesis (use of inductions, accepted as first principles, to explain observations).

The book s chief vehicle for creating an intuitive understanding of solutions of Schrodinger s equation is the world s largest and to the author s knowledge, virtually only library of line drawings of exclusive orbital models of chemical species electron density profiles.

By focussing attention on fundamental physical principles and by avoiding use of atomic orbitals and, thereby, mathematical complexities associated with Schrodinger s equation (the only source of atomic orbitals), the book s essays provide a scientifically sound, student-friendly introduction to modern valence theory.

Repetition of fundamental ideas, here and there, is intended to make individual essays understandable and interesting, each by itself, so that readers may examine them in any order, in leisurely walks, so to speak, in the big garden that is valence theory, picking bouquets to their liking. "
