These are the chemical equation layouts used with my molecular models and balancing activity sheets. Included are skeletal equations for 1) Combustion of Methane Gas, 2) Combustion of Propane Gas, and 3) Photosynthesis. An answer key is included as well. Be sure to check out the companion Power Point that will guide your students through this original method for learning how and why chemist balance equations - our recipes for chemical change. This is a proven activity that makes learning meaningful and interesting. Must try!
