Abstract

---

This study was analyzed the data and the results acquired by the gifted science students in three chemistry experiments performed during the 1st semesters of 2005 and 2006. The three chemistry experiments involved measuring the density of ethanol and copper, determining the molecular weight of isopropyl alcohol by ideal gas equation, and determining the chemical formula of copper (II) sulfate pentahydrate. The gifted science students' experimental data pooling from the three chemistry experiments indicate that determining the molecular weight of isopropyl alcohol by ideal gas equation has a higher range of percentage errors than measuring the density of ethanol and copper. The difference in standard deviation for determination of molecular weights of isopropyl alcohol was larger than the other experiments because of diverse variables including temperature, pressure, volume, and weight. These findings led us to conclude that by accumulating the gifted science students' data annually, chemistry teachers can better challenge gifted science students to think logically, analyze errors, create solutions, and interpret their resulting data.
