As you walk around the neighborhood, choose a tree with colorful leaves.  Talk about the color of the leaves and ask, "What do you think will happen to the leaves as the weather gets colder?"  Then watch this tree throughout the year to see what happens.  Collect leaves, acorns, chestnuts, or seeds and put them in a grocery bag.  Turn a long strip of masking tape inside out and make a belt to stick the leaves on.  When you get home you can glue or tape your new treasures on paper or cardboard.  Talk about how they are alike and how they are different.

Other Ideas:

• Make "binoculars."  Take two empty paper towel or toilet paper tissue rolls.  Tape the two rolls together, side by side.  Attach a string to the rolls.  Put the binoculars around your child's neck and ask, "What can you see?"  Your child may want to use crayons or markers to decorate the binoculars.
• When walking, ask your child, "How many ways can you walk?"  Use the words "forwards, backwards, sideways, giant or large steps, baby or little steps, fast steps, slow steps."  Ask, "Can you hop like a bunny?  Can you waddle like a penguin?  Can you jump like a frog?  What else can we do?"
