Weather: Unit Conversion & Significant Figures

With the HHS teachers out of the classroom for a Professional Development meeting on Thursday, students worked independently in small groups on an activity called Can You Lift It? The activity called for students to measure and calculate the interior volume of the classroom and then use that volume, along with density values that needed to be researched, to calculate the mass of the room filled with the indicated materials.  The activity required students to successfully use dimensional analysis.

To help students better understand how to perform dimensional analysis calculations, the Dimensional Analysis section of Appendix A in the back of the textbook (pages A16-17) was offered as extra credit (+10EC).  Additionally, the Scientific Notation section (Appendix A, pages A14-16) was also offered.  Students are also encouraged to watch the Crash Course video below for additional instruction on both topics:
