In this article, the author describes an activity using physical models -- each a clear plastic box enclosing a miniature coastal town, complete with real water in the "ocean." This activity shows students a natural cause-and-effect relationship that is scientifically simple, yet even many adults don't grasp the worldwide implications:…

This article is a presentation of a three-day sequence of lessons that engaged fifth-grade students in an exploration following the activities of scientists. From asking questions and analyzing data, to engaging in scientific modeling, to defending their theories to the scientific (classroom) community, these fifth graders were mirroring how…

The inclusion of engineering in the Next Generation Science Standards (NGSS) as a key component of K-12 science learning has provided both opportunities and challenges for elementary teachers. One challenge is integrating the design thinking processes that undergird engineering with core science concepts and current issues facing scientists and…

The "Next Generation Science Standards" ("NGSS") shift what it means to teach and learn science. One significant change emerges from the central role of discourse. As the practices are language-intensive and the performance expectations explain what a student should be able to do in science, every student must learn the…

Earth's surface is constantly changing. Weathering, erosion, and deposition break down Earth materials, transport those materials, and place them in new locations. Children see evidence of these processes all around them. The sidewalk or playground surface cracks and has plants growing in it. Pieces of a rock wall or the sides of a building…

Real science means wrangling with peers over real ideas. Wouldn't it be thrilling to emulate a real life model of science in action in classrooms? How? By starting with a great, hands-on activity modeling an object in space that introduces both key vocabulary and science concepts with visuals to support retention and learning; encouraging…

Reports on the use of 3D topographic models to teach Earth Science. Relates how students at a middle school made cardboard cut-out models to illustrate plateaus, a volcanic mountain, and other landforms. Provides teaching suggestions for the activity and a grading rubric. (MM)

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 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)

Presents several classroom ideas to help students understand their relationship to and their place in the universe as well as how difficult it would be to find life beyond Earth. Lists activities for children including the "Map Procedure," the "Model Procedure," and "Good Ol' Sol." (CW)
