Lab isn't just about “getting the right answer,” although that's what your students may tell you. Learning how to design an experiment, based on scientific principles and logical reasoning, is often overlooked when students have to follow rigid procedures. Use this guided-inquiry activity to refocus your students and help them develop good critical-thinking skills.
The purpose of this inquiry-based lab is for students to design and carry out a sequence of chemical reactions to separate and identify iron(III), zinc, and silver ions in water. Pre-lab preparation built into the activity will help students plan their tests and be successful in the lab. Comprehensive Teacher Notes with sample data and answers to all questions ensure that teachers will know what to expect and can properly guide the students. This student-directed activity is a great review of chemical reactions!
Complete for 30 students working in pairs.
