Nothing brings out the best in eighth-grade physical science students quite like an engineering challenge. The wind turbine design challenge described in this article has proved to be a favorite among students with its focus on teamwork and creativity and its (almost) sneaky reinforcement of numerous physics concepts. For this activity, pairs of…

Most middle school students comprehend that organisms have adaptations that enable their survival and that successful adaptations prevail in a population over time. Yet they often miss that those bird beaks, moth-wing colors, or whatever traits are the result of random, normal genetic variations that just happen to confer a negative, neutral, or…

The author was looking for a demonstration that actually used wind shear forces to set up the tornado effect when he saw a video produced by The Tornado Project called "Secrets of the Tornado". This video not only shows dozens of actual tornadoes, but also gives construction techniques for several different styles of tornado boxes that are…

There is a dynamic synergy between the visual arts and the natural sciences. For example, science relies heavily on individuals with visual-art skills to render detailed illustrations, depicting everything from atoms to zebras. Likewise, artists apply analytic, linear, and logical thinking to compose and scale their work of art. These parallel…

"A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas" emphasizes that the practice of science is inherently a model-building activity focused on constructing explanations using evidence and reasoning (NRC 2012). Because building and refining is an iterative process, middle school students may view this practice…

Describes the preparation and importance of a project where junior high school students stenciled "No Dumping! Flows to the Bay!" on storm drains in the area of their school. (PR)

Describes combining the simple activity of collecting monthly student height measurements with the technology of using a computer spreadsheet for a year-long activity that teaches measurement and data manipulation. (PR)

In eighth grade, students usually learn about forces in science class and linear relationships in math class, crucial topics that form the foundation for further study in science and engineering. An activity that links these two fundamental concepts involves measuring the distance a spring stretches as a function of how much weight is suspended…

Describes a project where students build their own catapults and modify them to solve four problems. Suggests the unit be integrated with a social studies unit on the Middle Ages. (PR)
