The document provides questions for a student to design an experiment on how acids affect teeth. The student is asked to identify the independent variable they will change, how they will change it, which variables will be kept the same, the dependent variable they will measure, when they will take measurements, whether repeats will be done, and to draw a blank data table to record results. The questions are part of an assessment for an IB Middle Years Program on designing experiments.
