Each team goes on a scavenger hunt to find objects of
various ages and place them in relative order of age according
to slips (see picture to right). All teams then do one
collective grouping (note how relative age then changes).
Integrate into the group's timeline: Dinosaur, meteor
crater, Pleiades Cluster (will be in same cluster as dinosaur),
Hubble Deep Field, hydrogen, Great Wall of China.
