Mole Conversions: 1- & 2-step with format

Wed, 11/05/2014 - 19:52 -- DAVID LICATA
Screenshot of a portion of the worksheet

This worksheet asks students to do basic conversions of mass or molecules to moles and vice versa. The worksheet requires students to complete their work in a particular format and to inlcude number, unit, and chemical identity for each item in the "given," in each conversion factor, and in the answer. It gives students basic practice in this mathematical exercise while inforcing good habits that encourage "unit analysis" (or dimensional analysis).

Time required: 

This worksheet can be used as an in-class or as a homework assignment. The ten items on the first page should take 20 to 30 minutes. The ten items on the second page should take 30 to 50 minutes.

Finding and Writing Molar Mass Screenshot

This worksheet is intended to be used as a "Guided Instructional Activity" (GIA). It asks students to find the molar mass of selected elements and write the molar mass as two equivalent fractions ("conversion factors") and as an equality. In each representation, students are forced to give the numeral of the measure, unit, and identity of the chemical.

Time required: 

About 45 minutes.

AACT at BCCE

Mon, 07/21/2014 - 16:53 -- Emily Bones

Physics teachers have AAPT, biology teachers have NABT, and starting this fall, chemistry teachers will have AACT. We are happy to announce that the American Association of Chemistry Teachers (AACT) will be accepting charter members starting on Aug. 4 at BCCE in Grand Rapids, Mich. But if you aren’t attending BCCE, you can join AACT by visiting teachchemistry.org on Aug. 4, and you’ll still have the status of charter member.
