I found an added cost that gave me buyer’s remorse. At first I was excited about the whole kit for $25 with free shipping using Amazon Prime. However, when one gets to the point of cashing in the voucher, there is an additional $7.95 to get your caterpillars. That makes the project $33, too expensive for a 6 weeks class with a $50 lab fee. I do not think I will use this kit for the Fall course. Nature Gift Store sells two cups of caterpillar for $23.93 with shipping, and that would be $11.97 per student. I am going to try to make our own cages out of wedding veil material and cardboard. This kit costs too much for my class, since there are other experiments that need resources.
