Science and engineering practices (SEPs) and crosscutting concepts (CCs) constitute a significant part of "A Framework for K-12 Science Education" (NRC 2012). As teachers, the role of the authors is to highlight the pivotal role that both scientific knowledge and the practices used to generate knowledge play in learning. This article…

Have you ever heard of a Maglev train? Who would be crazy enough to think that exploring how a high-tech train little known in the United States works with a group of fourth-grade students would yield understandings about the properties of magnetism, force and motion, and inquiry science? Fortunately, the authors--a college methods professor and…

Simple activities are described which use paper clips and straws or a board to demonstrate the properties of the lever. (BB)

"The Dirty Water Challenge" is a fun activity that teaches children about their environment in an engaging and practical way. Inquiry is embedded within the practical--students have to design, plan, and then build their own design of water filter. Students are exposed to important concepts from a variety of scientific disciplines, including how…

Provides guidelines for simple acceleration experiments with string and attached weights as a means to stimulate the reticular activating system (RAS) of the human brain. Several methods (discrepant events, curiosity, choices, and doubt) are suggested for promoting RAS high-level thought. String drop experiments provide concrete experiences with…

Describes a magic show designed to encourage young children in physics and chemistry. Discusses how a little "razzle-dazzle" can effect children positively. Tells how to organize and perform a magic show. Details six tricks that focus on principles of chemistry or physics. (CW)

Describes a hands-on lesson in magnetism designed to be used with upper elementary grade students. Emphasizes structured experiences which involve the student in measuring, data collecting, graphing, and extrapolating information. (TW)

Presents activities that utilize balloons to encourage students to explore questions related to scientific concepts. Concepts explored include light, heat, charged ions, polarization, and the sense of smell. (MDH)

Uses a projector, a prism, and two screens to demonstrate the composition of white light and detect color. (MDH)

Uses a discrepant event to teach students about volume and area. Outlines directions for class demonstration, needed materials, questions, a story problem, and related activities to perform this assignment. (Author/RT)

Describes several science activities designed around the upcoming Winter Olympics ice skating events which demonstrate the scientific principles behind the sport. Students learn that increasing the pressure on ice will lead to the ice melting, the principle involved in the spinning swing, and the technology of skates and skating outfits. (PVD)

Presents a unit of three lessons to teach Newton's Laws of Motion. After rotating through learning centers, answering questions, and recording observations, students are asked to generate a "class law" that explains the scientific phenomenon they observed. (MDH)
