Can anyone help me find the magic in middle school chemistry? DS12 really needs to understand by doing and I am kind of stumbled for ideas.  For instance, when DS was younger and had trouble grasping fractions, I used baking.  1/4 cup of an ingredient versus 1-1/4 cup would drastically alter his creations.  The difference between a t and T mattered.  We broke everything down and even made our own cleaning supplies just to get fractions down.
For middle school chemistry I have bought skittles to make atoms and followed an obscure youtuber to get the basics of atoms (protons, neutrons , electrons, AMU, etc), but now we are up to Lewis Dot Diagrams, covalent bonding, energy levels and DS12 is shutting down at a lot of data memorizing.  I know there is magic in chemistry.  Any suggestions to unlock it? I really believe DS12 is a scientist level at heart.  He loves experimenting and blowing things up.  TIA and wishing everyone a wonderful 2017!
