It was one of the first days of spring, and Cara Murphy had her work cut out for her.
In a field in St. Louis’ Tower Grove Park, the outdoor educator sat on a blanket, surrounded by more than a dozen loud and distracted children between the ages of 4 to 10. She held a large poster covered in illustrations of animals and plants. Some children pointed and named animals on the poster; a few focused more on digging up the dirt around them.
Murphy is teaching a class called "Food Web” about how animals, plants, the sun and other organisms consume energy from each other. It’s one of several classes she started teaching this year for In The Field, an outdoor education organization she recently founded.
