Apologia Chemistry: Timelines

The overhead that worked YESTERDAY and did NOT today.  We did annotate the periodic tables: group names, metals and no metals, s d p f blocks, etc.  Then we did examples of conversions, sig figs, and scientific notation.  Lastly, we started the timelines.  Wooooo!  None had made timelines on graph paper previously.  Sigh.  Here is the list of elements I used and some photos.  The kids did them all a bit differently.
