Am teaching Year 1/2 starting next week. While doing one last tidy up of our veg garden (no doubt it won't be touched until next Spring) I came across hundreds of caterpillars happpily munching away on the cabbage. Just wondered would it be appropriate to have some kind of tank to display them in, in the classroom? A kind of 'Living World' area of the class. Or is this just digusting to have in the classroom? Thanks for advice!
