This science unit focuses on measuring skills using students' own sneakers and the unit of measure. Two activities with differing levels of difficulty are presented. (MT)

Described is a workshop for grades 5-8 school teachers and students related to synthetic polymers. Participants become familiar with polymer theory and practice experiments they can use in class. Sources of materials used in the workshop are listed. (RH)

Orthodontic braces and how they work are discussed. A science unit and task card on teeth is provided. (MT)

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)

Tree frogs are small (2-5 cm) animals which not only interest students but also can be maintained in classrooms for a few days. Characteristics (species, ranges, habitat, reproductive cycle, and locomotion) and housing/care needs are described. Long-term maintenance is not recommended due to the difficulty of providing live food. (DH)

Suggests using crickets for classroom activities, providing background information on their anatomy and reproduction and tips on keeping individual organisms or a breeding colony in the classroom. (JN)

Here are 10 activities guaranteed to enrich your science curriculum and to increase your students' interest in the world of insects. (Author)

Designed for elementary school teachers, this article describes the recent eruptions of Mt. St. Helens, provides basic information on volcanos, and gives instructions for making a model volcano in the classroom. Resource materials for students and teachers on volcanos are listed. (SJL)

Presents a unit on volcanoes for third- and fourth-grade students. Includes demonstrations; video presentations; building a volcano model; and inviting a scientist, preferably a vulcanologist, to share his or her expertise with students. (JRH)

Presents hands-on science activities using inexpensive, hand-held microscopes and slides made from simple, readily available materials. The article describes how to introduce students to microscopes and presents directions for using the microscopes and making slides. A student page investigates fingerprints with microscopes. (SM)

Twelve desk-top experiments and demonstrations which illustrate properties of and facts about gas are presented. Each experiment includes: purpose, materials needed, instructions, and a list of facts and properties that have been observed. Several of the activities also include questions for students and items for discussion. The topics of the…

Suggestions are made for using traditional Halloween activities, such as jack-o'-lantern carving, bobbing for apples, and trick-or-treating, for classroom learning. (SJL)

Kite flying as a fun class project is proposed as a way of letting students apply what they've learned about air. A design for a kite made from a trash bag is provided, as are kite flying tips and resources. (MT)

A study is described which demonstrates that children create naive theories of science that are highly resistant to change, even when other concepts are seemingly understood. Ways of promoting conceptual change in children's understandings of how the world works are suggested. (MT)

Magic can stimulate children to think creatively and retain what they learn. This article offers tips and step-by-step instructions to bring magic into the classroom. Children learn scientific principles, are required to read and follow sequential instructions, and are encouraged to stand in front of the class. (MT)
