Density only appears in the 9th grade as density of gases.  8th grade has density in it.  Before it is taken out of Chemistry, this needs to be addressed. Density at the chemistry level would be at the atomic level and molecular packing.

Timeline is great for each nine weeks.]]> 2016-10-19 20:25:17 UTC https://padlet.com/evans_tracy9/chem/wish/131922904 Electron Configuration of ions is required for everyone but Orbital Diagrams are only required for honors.   Electron Configuration of ions are okay to teach up to you reach the  transition metals.  I think this this needs to be clarified to state that electron configurations of ions for elements in group 1A- 8A only Indicator AKS3G https://padlet.com/evans_tracy9/chem/wish/131924879 2016-10-19 20:35:36 UTC https://padlet.com/evans_tracy9/chem/wish/131924879 Chemistry AKS3, g, assessment makers should realize that the intent is not to write e- config, but to USE e- config, so consider giving e- config and asking students to predict reactivity. Or give before e- config and after e- config and ask students to conclude whether an electron has been added (negative ion) or removed (positive ion). https://padlet.com/evans_tracy9/chem/wish/131927140 2016-10-19 20:45:56 UTC https://padlet.com/evans_tracy9/chem/wish/131927140
