Oh, and you know those informations signs that are posted along some trails filled with all kinds of wonderful information that you'd like to read and share with your children? Snap a quick photo of them as you are walking by. Go through the photos after the hike and plan some fun lessons around them. Relive the excitement of the hike as your children learn and grow. Often one hike will provide a weeks worth of lessons and crafts.
Now it does not matter where we are, if we see a Red or White Oak our 5 and 6 year old will burst with excitement as they point out the tree :)
