We like bats over here. Batman, bat houses, bats + baseballs, etc. My mom actually makes bat houses, so we talk with the kids quite often about the many benefits of bats. And here is some of our summer fun with bats.
The Library hosted a special bat day with visitors from our state's bat conservatory. The kids got to see live bats from all over the world! Very cool! We ran into a ton of our homeschool friends there. Also this summer we happened across a couple of drowned bats, which we showed off (look, don't touch) to the group of kids we had for a backyard bbq. (Pass the potato salad, oh, and did you see our dead bats?) Ewwww!!! But the kids LOVED it. :)
Some great books on bats. Also, check out this free unit study on Stellaluna from the Homeschool Share! :)
