Introduction

Have you ever walked across a large parking lot on a sunny day and felt like you were roasting? That's because the asphalt gets really hot in the sun! Streets, buildings, and parking lots can get so hot that they raise the average temperature of urban areas by a few degrees. Do you think natural materials also heat up in the sun, or only man-made materials? Do this activity to find out!
