The third edition of Chemistry: The Science in Context provides additional
opportunities for students to test their understanding and practice their
problem-solving skills. Concept Tests, which ask students to stop and check
their understanding, have been added to nearly every section in every chapter.
Interactive Practice Exercises, new to the third edition, follow each Sample
Exercise. This edition continues the approach of framing the discussion of
chemical principles within environmental, biological, cosmological, and
geological contexts in order to make the science more relevant and memorable
for students. The COAST (Collect and Organise, Analyse, Solve, and Think about
it) problem-solving method is still used in every Sample Exercise, but the
steps have been applied more consistently and more often use estimation and
prediction-making as part of the problem-solving process.
