With #HomeSchooling can do things in not the typical order. I may be biased but imo teaching #Organic #Chemistry earlier would make it more fun and engaging.
Haven't done this in a while (year+) so especially for Kid2 (8th gr) this is somewhat new but comes (back) fast.
Fun puzzle to draw out all the structural #isomers of #alkanes - say upto C6H14
(remember CnH2n+2)

Kid1 (11th gr I guess) wanted to do more and on to #alkenes
