Not all American children get regular doses of fresh air. A 2012 report published in the Archives of Pediatrics & Adolescent Medicine found that only about half of U.S. preschoolers are taken outside to walk or play daily. And older kids aren’t faring much better, experts say.

Too much time inside contributes to obesity, attention problems, hyperactivity and lack of appreciation for the earth’s resources.

By taking kids outside regularly to explore nature, you can help them get physical activity and connect to the world.

From setting up bird feeders to camping, discover together what makes the outdoors great. Project Learning Tree, a nonprofit environmental education program, has great tips for family activities on its website to get you started.
