This is a great worksheet that combines learning about minerals with learning about the Periodic Table of the Elements and basic chemical formulas. The first page gives students some background info on how to read and use the Periodic Table. The second page is a chart of 17 different minerals and their chemical formulas. The task is for students to break down the chemical formulas into what elements are present in those formulas, as well as how many atoms of each are present. Great practice and review!
