Four!

Hottest day ever.
Had my first AP exam today...should have included a Rutherford/Thompson question...next time...
IMPORTANT: during summer assignment review the first few days, FOCUS on combustion and empirical formula of hydrate questions!
In Honors, showed the dissolving of NaCl video in D but forgot to in E and B...do so tomorrow.
Started A/B lab with Bunsen Burner stuff but must show other skills next lab and post lab safety writeup.
1-36 Element quiz tomorrow.
Must teach a lot faster and ask more pepper questions and keep them awake...ask if I'm going to slowly.
Show the Anand video for lab safety also...

When I do the atom and explain amu, I will start with the definition of the standard (i.e 1 meter is the meter stick and then the light distance) that 12.0000 g of pure C-12 is one mole of atoms of C-12 and then dividing by the eventually discovered number will give you the mass in g of 12 amu.
