Apologia Chemistry: Nuclear Atom

Today, we are working on some POGIL exercises: ChemActivity 1 The Nuclear Atom  (Key) and    ChemActivity 2 Atomic Number and Atomic Mass (key) (Scroll down to locate ChemActivity 2.).   Some of this material is new and some review.  I want to wrap up moles before we tackle electron configurations and flame tests.  I think the packet and a final Stoich review will take the entire class.

Wow.  This exercise was painful.  We completed the first part and skipped right to the mole section in the second part. No, I am NOT sure the kids understand the relationship between amu, atoms, and molar mass.  I think they understand the relationships among atomic number, atomic mass, number of protons and neutrons.  I believe they understand the relationship between charge and numbers of protons and electrons.  Am I certain?  Nope.  Here are pix of my notes from class.
