Hit outdoor exhibits or parks first. This will help ensure that once you're inside, your child is ready to calmly focus on the exhibits instead of racing around expending pent-up energy. Review the floor plan. Locate restrooms, snack areas, and your must-see exhibits. Look for water.
Most kids love anything to do with water.
So if your child hasn't led the way, you might want to point out those exhibits with splash appeal. Look for age-appropriate activities. If the Web site doesn't specify age ranges for each gallery, ask the staff which ones best suit your child's age. Turn the experience into an informational treasure hunt. Be sure that pre-readers can figure out the answers without having to read displays.
