Sampling Button Populations, An Environmental Investigation.
National Wildlife Federation, Washington, DC.; Minnesota Environmental Sciences Foundation, Inc., Minneapolis.
This environmental unit is one of a series designed for integration within an existing curriculum. The units are self-contained and require minimal teacher preparation. The philosophy behind the units is based on an experience-oriented process that encourages self-paced independent student work. This particular unit is an introduction to the techniques of sampling. Using button and bean populations, students learn various ways of sampling. Next, they learn to use this data by constructing simple graphs based on their statistical analysis of the samples. At the end of the unit are eight additional activities designed for independent study. Students can investigate variations within human and plant populations and statistically study their frequency through random sampling techniques. This unit is designed for students in grades 3-9. Each activity contains a list of materials, directions, and discussion questions to aid the teacher. (MA)
