This lesson is designed to be completed in one 80-minute section. The teacher will facilitate the sharing of student titanium dioxide solar cell results with emphasis on variables during data collection. Teachers will demonstrate spreadsheet sorting for students and allow time for students to draw conclusions from the class data using an optional framed paragraph for conclusions. Teachers will guide students in making connections to the titanium dioxide, anthocyanin, and potassium tri-iodide electron system.
