The Nerve to Conserve

While not explicitly stated in the standard, the idea that the Law of Conservation of Mass is conditional to a closed system and this is the focus of my lesson. This lesson starts with an investigation of seeds growing in a jar with students quickly recording the mass each day for 5 days. On the 5th day, students complete 2 more investigations, half with closed systems and half with open systems. They will compare the final masses and draw conclusions independently and through class discussions about the condition of the Law of Conservation of Mass.
