This is an excellent lesson that can be modified a number of ways. I find that it fits well with Science and Technology Standards 2.4.1 and 2.4.2. 2.4.1: Identify parts of the human body that can be used as tools. 2.4.2: Identify technologies developed by humans to meet human needs. Investigate the limitations of technologies and how they have improved quality of life. Students could identify how teeth can be considered a tool. They could discuss the toothbrush (and its evolution to items like Sonicare.) The experiments will help them understand the limitations of the toothbrush, and how their choices affect their teeth.
