Children have a wonderful way of creating their own games when in the great outdoors, away from video games and television. Emulating squirrels gathering nuts, climbing trees, visualizing shapes in clouds are all examples of this. Kids love to go rolling down hills, racing each other over fields, and catching butterflies, moths, and fireflies.
If they have a notebook or sketchbook, children can draw the wonderful things they discover. Give them a plastic magnifying glass to study ants and other bugs. They can make leaf rubbings by placing the leaf vein side up under one of the pages of their notebook and lightly scribbling. Kids can write or draw each new life form they discover, and then follow their list to see if they can find them again the next day. A notebook makes a wonderful keepsake of the trip. They can share their findings with an adult, who can use this as a teaching opportunity.
