Toxins: Avogadro’s Number

For Lesson 76, students gained practice working with scientific notation in the context of Avogadro’s Number (really big numbers) and the mass of small numbers of particles (really small numbers).  We began class by working through part B of the ChemCatalyst from Lesson 75.  Notes from the work are shown below:

We then transitioned into the Lesson 76 Worksheet (we did not use the Lesson 76 PowerPoint but it is provided here for reference).  We worked through some of the table on page 2 of the worksheet, and then students used the remainder of the class period to work together to complete the worksheet.  For homework, students were assigned to complete any 3 problems from the textbook.
