Pages 31-37 | Published online: 07 Aug 2010
 

Abstract

This authentic inquiry-based chemistry experiment provides high school students with an opportunity to investigate the effect of toothpastes on the rate of tooth decay. Students need to design and carry out a fair test to compare the effects of different brands of toothpaste. The author has developed rubrics for assessing students' planning skills and written laboratory reports.
