Looking at a skeleton can give you a key to what the animal is and how it lived. Did it swim, fly, walk or slither? What did it eat? At this nature workshop, kids will take a mystery mammal skull through a special question and answer maze and "key it out" to find out what animal it is.

For ages 7 and up. 9:30 to 11:30 a.m.

At Powder Valley Conservation Nature Center in Kirkwood. Call 314-301-1500 for reservations.
