This lab manual is intended to accompany the seventh edition of Chemistry in Context
. This manual provides laboratory experiments that are relevant to science and technology issues, with hands-on experimentation and data collection. It contains 30 experiments to aid the understanding of the scientific method and the role that science plays in addressing societal issues. Experiments use microscale equipment (wellplates and Beral-type pipets) and common materials. Project-type and cooperative/collaborative laboratory experiments are included.
