Humans are one of the few organisms that live in such a wide variety of habitats. As advanced builders and tool makers, we are able to make all varieties of clothing, as well as cooled and heated shelters. Most organisms live in a very specific kind of environment. Even just outside your school there are a variety of habitats that support different kinds of organisms. Have you ever wondered just how many living things there are in different locations? Temperature variation is one of the factors that influence where organisms live. Some like it hot and some like it cool!

During this activity you will investigate a small area of a field or wooded area and determine the range in temperatures found in it.

In your group predict the range of temperatures that you might find in a one square meter area if all the temperatures are taken within the same short time period. For example, would the temperature be the same under a rock as it is in grass?
