Some of the most important scientific studies are associated with either incredibly large dimensions (e.g., the universe) or extremely small proportions (e.g., the cell). While a teacher's curriculum may often switch from mega-expanses to minutia, they should question how easily students comprehend the change in sizes. This article addresses…

The average American produces around 1,600 pounds of garbage every year, and it is estimated that 50 percent of that waste is material that could be composted (Clean Air Council, 2012). Instead, most is sent to landfills and incinerators. In technology and engineering education, a great deal of time is spent in talking, teaching, and thinking…

One tool for enhancing students' work with data in the science classroom is the measure line. As a coteacher and curriculum developer for The Inquiry Project, the author has seen how measure lines--a number line in which the numbers refer to units of measure--help students not only represent data but also analyze it in ways that generate…

To help teachers get off to a good start, this paper presents the updated "Back-to-School Guide" that is brimming with new-media ideas and resources. It outlines ten tips, along with easy-to-use tools, that will help teachers build their classroom community, survey students to bring out their ideas, and make learning more collaborative. Links to…

The American Association for the Advancement of Science and the National Academy of Science have emphasized the need to design curriculum such that students do not simply learn about science, but also do science. Although obviously the knowledge-building practices among scientists and children in elementary school science classrooms will always be…

Highlights science activities that focus on rivers. Describes how students can create model rivers in small pans and suggests activities to use with children when visiting rivers. Also annotates four children's books that have rivers as a major theme or plot component. (MDM)

Describes a science unit used in a fourth-grade class to teach students about Bernoulli's law of flight, the similarity of tetrahedrons to birds, and the construction of tetrahedron kites. Also includes thought-provoking math questions for students. (MDM)

Using the example of a ten-year-old boy working on a science project, the author discusses the question of when and how much the teacher should intervene and direct a child's independent learning activity. (SJL)

Since 1975, the Association for Childhood Education International has published a column called "Classroom Idea-Sparkers" in each issue of Childhood Education journal. The column provides practical help for classroom teachers, preschool through middle school, offering educators ideas and activities to help extend learning and make it more relevant…

This article discusses how Magnetic Levitation (Maglev) can be taught to gifted students in grades 4-9 using hands-on activities that align to the National Science Standards. Principles of magnetic levitation, advantages of magnetic levitation, construction of a Maglev project, testing and evaluation of vehicles, and presentation of the unit are…

Reviews five compact disc-read only memory (CD-ROM) products and one video series that focus on science projects: (1) "Body Park" (Virtual Entertainment); (2) "The Magic School Bus Explores the Solar System" (Microsoft); (3) "The Magic School Bus Explores the Human Body" (Microsoft); (4) "Science Curriculum Assistance Program" (Demco); and (5)…

Through the use of science-reading kits, one teacher develops practical application of children's reading skills. Each child designs and builds appropriate materials for science learning kit on the subject of his/her choice. (SA)

Describes secondary science programs designed to meet the educational, behavioral, social, and emotional needs of students who do not appear able to benefit from, or adapt to, the traditional educational system. Includes an outline of lessons encompassing a multidisciplinary, computer integration plan for hatching chicken eggs, and directions for…

Children with special learning needs participate fully in the authors' science classes every day; their job as teachers is to bring about meaningful science connections for all students, including those who do not communicate their knowledge most effectively through the ways most typically associated with classroom learning (i.e., reading,…
