My son loves trains. So I came up with a train related twist to an inspection of the periodic table. We sat and cut up a copy of the table and then rearranged each element as a ‘station’ on an underground rail system. Each line represents a characteristic shared by the elements on that line.
After (quite) a few drafts, and more time than I care to admit, we ended up with this.
It was constructed with the help of Metro Map Creator (no way I could have done it without this neat web app). If anyone fancies building some more lines I’ll happily send you the saved file (share using a creative commons attribution, non-commercial, share a like license) .
Let me know if you spot any errors.
Now on version 1.4. New line added, to show elements that were discovered via synthesis and then found in nature.
