Summary:
Transform your chemistry labs with this guide to argument-driven inquiry. Designed to be much more authentic for instruction than traditional laboratory activities, the investigations in this book give high school students the opportunity to work the way scientists do. They learn to identify questions, develop models, collect and analyze data, generate arguments, and critique and revise their reports.
