Described is an experiment designed to illustrate photosynthesis. The experiment is based on a classic experiment performed by vanHelmont in the sixteenth century. A list of materials, procedures, and concepts are discussed. Variations are suggested. (CW)

The construction and stocking of an in-class pond is discussed. Suggestions for eight activities using the pond are provided. A list of 15 references is included. (CW)

Describes the construction of an effective plant incubator for classroom use using a five-gallon plastic bucket. (JRH)

Discusses some of the remarkable capabilities and fascinating behavior of plants. Describes several simple experiments that young scientists can accomplish with plants to demonstrate their ability to sense, react, and adapt to their environment. (JJK)

The slime mold Physarum polycephalum provides an easily maintained classroom plant which can act like an animal. Directions are given for: acquiring the organism; activating it; observing its life cycle; and viewing protoplasmic streaming. (DH)

Suggests science activities using amaryllis plants. Includes information on growing the plant and its annual growth cycle. (SK)

Provides: (1) background information on trees, focusing on the parts of trees and how they differ from other plants; (2) eight activities; and (3) ready-to-copy pages dealing with tree identification and tree rings. Activities include objective(s), recommended age level(s), subject area(s), list of materials needed, and procedures. (JN)

Project AIMS (Activities to Integrate Mathematics and Science) has as its purpose the integration of subject matter in grades K-9. Field testing of the curriculum materials produced by AIMS indicates that this interpretation produces the following beneficial results: (1) mathematics becomes more meaningful, hence more useful; (2) science is…

Describes a game in which elementary school students learn the importance of plants and some techniques of plant identification. (LS)

Describes an experiment designed to introduce students to chromatographic techniques. Also describes a teacher demonstration in which leaves obtained during the spring and fall are analyzed using chromatography. Procedures for both the experiment and the demonstration are outlined. (JN)

Using many different media, students can turn leaves into images which can be used for study, bulletin boards, collections, and identification. The simple techniques described include pastel printing, smoke prints, ink or tempura printing, bleach printing on t-shirts, ditto machine printing using carbon paper, and making cutouts. (DH)

Samara (winged seeds from maple and ash trees) can be used for open-ended inquiry or a series of directed science activities. Attributes, observations/inferences, drawing, motion, floating, seed structure, creative design, and measurement are some of the suggestions for classroom use of these seeds. (DH)

Provides: (1) background information on how trees reproduce, what they need to survive, and where they grow; (2) six activities dealing with these topics; and (3) a ready-to-copy page showing trees around the world. Each activity includes an objective, recommended age level(s), subject area(s), list of materials needed, and procedures. (JN)

Provides: (1) background information on plant and animal relationships in forest communities; (2) four activities dealing with these relationships; and (3) five ready-to-copy pages for students. Activities include objective(s), recommended age level(s), subject area(s), list of materials needed, and procedures. (JN)

Discusses various plant parts used as food (including seeds, roots, stems, and leaves), emphasizing the origin of plant materials bought in the supermarket. Also discusses several concepts of nutrition, menu planning, and the relationship between food and energy from the sun. (JM)
