You Will Need:
A collection of leaves, seeds, grass, sticks, feathers, etc. and clear contact paper.
Take a walk with your child and collect treasures from the ground. Tape a piece of clear contact paper, sticky side up, to a flat surface. Help your child arrange the treasures on the contact paper. Be cautious that young children don't put small objects in their mouths.
This can be done on a table or floor. On the floor, you tend to have closer physical contact with your child.
