The document is meant to act as a resource for elementary through middle school teachers, featuring 6 science activities connected to Indiana state standards with grade-appropriate science connections aimed toward 5th, 6th, 7th, and 8th grade.
Students might have experience in 3rd-6th grade with converting basic ideas such as volume and measurements. This is intended to expand that idea and introduce the mole. It's also a general interactive conversion/exchange activity. All items in here are just based on what we had available and convenient, so feel free to swap out items such as rubber stoppers with something more easily available to you such as pieces of dry pasta.
