In Chemistry, I am currently teaching the mole concept. Students were trying to understand what moles are and how to do calculations involving moles. The students were completing a lab where they had to determine the mass of three samples. This lab gave them the opportunity to use different types of balances. Next, the students had to determine the number of moles and number of representative particles associated with the masses of their samples. After determining the masses of the samples and cleaning up the lab, the students watched the following YouTube videos from ChemistNATE (http://www.youtube.com/user/chemistNATE):
Calculating Molar Mass: ChemistNATE
Calculating Grams from Moles: ChemistNATE
Calculating Moles from Grams: ChemistNATE
This lab involved hands-on learning skills, lab process skills, and calculation skills. Integrating each of these skills in one activity improved student understanding of a difficult concept.
