Como Zoo has a free preschool program every Thursday through April that introduces basic science concepts. Today we dug for worms, examined plant seeds and parts under a microscope, planted sunflower seeds, made a puppet, and participated in story time, which ended with a visit from a live toad and a rabbit.
Since we were at Como, we also strolled through the tropical rainforest room, where we saw a leopard gecko, and through the conservatory to the koi pond. An exciting morning for two boys who are fascinated with animals.

Sounds great! A good way to spend a Thursday morning.
