File folders can be used effectively to develop and retrieve information about animal classification systems. Animal characters are drawn separately on the front side of a file cover and holes are punched next to each character. (PS)

Describes an approach to teaching animal classification by applying a scientific examination of the types and arrangement of the teeth. This approach may be used by high school students. (HM)

Presents activities that have been proven to teach young learners to sort and classify objects that contain more than one attribute. The activities require that students employ the use of sorting hoops and attribute blocks to create Venn diagrams, the assembly of which requires practice. Includes cross-curricular uses of these learning tools.…

Describes science activities used in an eighth grade class such as metric measurement exercises, classification problems, experiments with batteries and bulbs and a series of activities concerning chemical reactions. (BR)

Describes the construction and use of a shell-discovery kit for students to employ in actively investigating the natural world. (WRM)

Presents several activities designed to teach students about the characteristics, classification, life cycle, and uses of the luffa (gourd). (WRM)

Describes an inexpensive technique for providing student opportunities to observe and identify the variety of small animals living in the first few inches below the surface of the soil. A classification key to some small soil animals is also presented. (HM)

Recommends the use of beans as an inexpensive, durable, and readily available resource for developing science-process skills in K-8 students. Shares strategies for using beans in graphing, patterning, and classifying. (DDR)

Describes an activity for studying weeds in grades four through nine. "Wanted" posters are prepared with the scientific name of a common weed and a few identifying features. Students find the plant, give it an "alias" or common name, and then draw the "wanted" picture. Presents six wanted posters and describes expansion lessons and follow-up…

Discussed are the advantages and processes of making collections with children. An activity for making a classroom collection (herbarium folios) is described and includes materials and procedures. The processes of collecting and classifying are stressed. (CW)
