Five For the First Nora Walsh shares some of her favorite FIRST WEEK of school activities for the chemistry classroom!
	Seashell Chemistry Placing dry ice in limewater is a great demonstration to accompany discussions on a variety of chemical topics, including the impact of ocean acidification on marine organisms that depend upon the formation of CaCO3.
Candy and Car Exhaust with Acid Base Indicators The candy "Toxic Waste" and "Pop Rocks" are fun ways to show changes in acid base indicators. There is also an easy way to test car exhaust with an indicator.

VSEPR Flat Packs: An Economical Model Kit Molecular geometry is a center piece to a student’s understanding of intermolecular forces. Unfortunately, many students don’t have the special skills to “see” the geometry without a model kit. Check out this inexpensive take-home model kit!
	Using Digital Card Sorts Ashley Green shares a variety of digital card sort activities!
First Day Questioning Practice This "first day" activity is an opportunity to help students practice asking good questions!
