      Can be differentiated for ELL's by using pictures to demonstrate the history of toothbrushes, and how to properly care for your teeth. Higher ability students could keep a journal of the experiments complete with pictures.

    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.

    Simple demonstration on how gears work and can create great conversation on how they work and what they have meant to society.
