Students make predictions and generalizations about a population by studying a sample. In the Kind of Bean Lab, students take a scoopful of dry beans from a population of beans. After students gather and count the beans, they record, organize, graph, and analyze their data.

Materials Preparation

Create a Bean Population. Create a bean population by selecting three different types of beans. Label a large container “bean population.” Fill a large container with the three types of beans and mix them thoroughly. Students should not be told this recipe. Each type of bean should be approximately the same size, and each type should be easily distinguishable from the others. It is important that the mixture have one type of bean that is most common, e.g., 1 pound of red beans, 2 pounds of navy beans, and 4 pounds of pinto beans.
