The Dissection & Scientific Drawing club recently tackled earthworms and rats. The girls (it accidentally turned out to be an all-girl club!) often start methodically and carefully, and by the end they are exploring with gusto.
We were amazed to see the length of a rat's intestine (herbivores have longer tracts than carnivores). Our final labs will include lilies and mussels (some surf and turf!), and fetal pigs for the finale.
