How did the temperature of the air and ground impact your results with the leaves and the rocks?
Did the temperatures above and below ground stay the same? Does the temperature of the air above the ground change the temperature below the ground?
What is the range of temperatures in your observation area?
What observations have you made about how temperature varies in different locations? Did the temperature changes dependent on the amount of sun, clouds, shade, etc. present?
What observations have you made about how temperature varies in different places of the same type of location?
Were any of your original temperature predictions not supported by the evidence you gathered with the probe? Think about why you made your original predictions. Now that you have more evidence have any of your original ideas about temperature variation changed? How?
