Students learn concepts on a need-to-know basis, evaluate data, and make decisions based on their observations and knowledge gained through the curriculum. The text features embedded labs and activities that give students the opportunity to apply their knowledge of chemistry. Each unit ends with an "putting it all together" (PIAT) activity, where students collaborate and use their knowledge gained throughout the chapter, both chemistry and real-life scenarios, to evaluate a potentially real-life problem.
