Presents an activity, appropriate for children in grades five through nine, that requires students to reconstruct a Lego structure after reading other students' written description of the construction process. Highlights the connection between explicit writing and scientific observation and involves students in observing, classifying, measuring,…

Describes the construction of a model to show circumpolar stars. (BR)

Presents a lesson that introduces students to polarized light using a problem-solving approach. After illustrating the concept using a slinky and poster board with a vertical slot, students solve the problem of creating a polarized light show using Polya's problem-solving methods. (MDH)

Outlines the formula and the preparation needed to design lesson plans adaptable to any science situation. Provides a detailed example using molds. (Author/MA)

Suggests making insect models to learn more about the world of insects. List of materials needed and recommended procedures are provided. Also suggests other interdisciplinary activities for investigating insects in the classroom, including the preparation of an insect zoo using the student-constructed models. (BC)

Presented is a cooperative learning activity in which students assume different roles in an effort to produce a relief map of the ocean floor. Materials, procedures, definitions, student roles, and questions are discussed. A reproducible map for the activity is provided. (CW)

Provides instructions to build an inexpensive device to demonstrate wave-motion to elementary school children. (MDH)

Provides instructions for the construction of a paper mache classroom planetarium and suggests several student activities using this planetarium model. Lists reasons why students have difficulties in transferring classroom instruction in astronomy to the night sky. (DS)

An activity is described in which students learn modeling skills by creating concrete models with familiar objects. Teaching methods, materials, procedures, and outcomes are discussed. (CW)

Provides instructions for constructing a model of a working thermostat and suggests several student activities using the model. (DS)

Reported are the results of a survey of elementary and secondary school students' portraits of scientists. Discussed are sample demographics, gender and race comparisons, scientists and role models. The positive results of these voluntary submissions are stressed. (CW)

Describes a science project in which students make models of polymers using polyvinyl alcohol solution. Students make T-shirts using polymer paint to remind them of their activities. (MDH)

Describes an activity that involves exploring a model cave made out of a two-person tent as a way to add science process to a thematic unit on bats and spiders. This multifunctional learning center provides students with a variety of hands-on experiences, helps students focus on observable things from nature, and emphasizes process skills. Lists…

Students explore the workings of the lever, wheel and axle, and the inclined plane as they build simple toys--a bulldozer and a road grader. The project takes four weeks. Diagrams and procedures are included. (PR)

Directions for the construction of a model bog habitat are provided including examples of plants and animals which may be suitable. Activities that use this model are suggested. Background information on the ecology and chemistry of the bog is included. (CW)
