Send the kids outside into the sun and find the signs of spring.
They get a point for each thing they find
Make a list of spring for them to hunt for, such as:
Sounds: peepers, knocking of a wood pecker, a bird singing, etc
Plant Life: A tree bud, a mushroom, etc,
Critters: a bug, a baby animal, a turtle, etc
Human hints: a baby in a stroller, laundry hanging outside,someone on a skateboard or bike
Think of things that have to do with your area
Take the kids to a park to play as well.
Have fun in the Sun!!
