@dtpolet Put fake fossils in play dough while teaching them about the layers and how we can guesstimate time based on the layers of things buried. Then let the playdough dry and exchange them, and let them break them and "dig up" the fossils and guess (from a color chart) hold old the fossils are.
@dtpolet I'm a mom so I was thinking, what would get my silly kids excited!? Haha. Good luck with your talk.
@omi I used your idea today in class! I didn't have layers but I made playdough balls in three different colours, each with a dinosaur inside. Didn't have time to let them dry, but the kids loved making dinosaur tracks and impressions afterwards in the soft dough.
They took their excavated dino to a station to find a matching picture, and learn their dinosaur's name. Next they put their dino picture on a chart in the Triassic, Jurassic or Cretaceous row, depending on the colour of the dough! It was great fun!
@dtpolet Thats awesome!
@omi what a great idea!
