Document changes in your neighborhood throughout the year. For example, on the first day of each month, you might observe some leaves from the same tree–from the earliest buds in the spring to the last remaining leaves in the fall. Draw them in your field notebook, take photographs of them, or press them between the pages of a heavy book. You shouldn't pick leaves or buds–collect items only if they have fallen to the ground. Or you might visit a river, stream, or pond periodically to document how it changes. You could even look for changes in the sky. At what time does the sun rise and set on the first day of each month? Where is the moon on that day, and what shape is it?
