Wetlands are great places to explore.
They contain all kinds of plants and animals that you just can't see without getting your feet wet. If you want to check out a wetland near your house, all you need is a pair of old tennis shoes or boots that you can get muddy and some curiosity. As always, before you head outside to explore, tell a responsible adult where you're going and when you plan on getting back - just in case. And try to take someone else along with you. You don't need to go far to find a wetland.
