Product Details

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. 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.

Performance Expectations

HS-PS1-1. Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.
HS-PS1-2. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
HS-PS1-7. Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.
