This article describes a lesson rooted in "tinkering," an approach to learning that encourages the use of authentic, hands-on experience to develop an understanding of content and physical materials. There were several desired outcomes for this lesson. First, the authors felt that tinkering was an appropriate approach to investigating…

Computational thinking--a set of mental and cognitive tools applied to problem solving--is a fundamental skill that all of us (and not just computer scientists) draw on. Educators have found that computational thinking enhances learning across a range of subjects and reinforces students' abilities in reading, writing, and arithmetic. This book…

Jennifer Miller is a special education preschool teacher at Grant Elementary School in Muscatine, Iowa. In this article, she describes how she created and implemented a learning center with three-to-five-year-old students in an integrated morning class (nine students; four on IEPs) and an integrated afternoon class (10 students; four on IEPs) to…

What if you could challenge your 11th graders to figure out the best response to a partial meltdown at a nuclear reactor in fictional Gammatown, USA? With this volume in the "STEM Road Map Curriculum Series," you can! "Radioactivity" outlines a journey that will steer your students toward authentic problem solving while…

What if you could challenge your 12th graders to understand car crashes in the context of physical forces, manufacturing challenges, government safety standards, and individual rights? With this volume in the "STEM Road Map Curriculum Series," you can! "Car Crashes" outlines a journey that will steer your students toward…

Students use tables of anthropometric data, their own measurements, underlying principles of physics, and math to solve a problem. The problem is to determine the height of a wall mirror, and where to mount it, so that 90% of the clientele can view their entire length without stretching or bending. (Author)

Presents a sample HyperQuiz, a strictly-for-fun, genius trapping contest for occasions when the syllabus and coverage do not bear down too severely. Promotes collaboration between students, library research, and development of scientific thinking skills. (JRH)

Presents a demonstration of kinematics principles that stresses conceptual analysis over equation manipulation. Aims at focusing students' attention on concepts by using comparative problems, allowing students to predict the outcome of the demonstration and explain the reasoning behind their predictions, and extending the context in which the…

Discusses the continuity equation and presents two real-life problems involving salmon survival and the construction of dams. (JRH)

Describes how Newton's Law of Cooling and the Method of Mixtures are used to solve the basic dilemma of whether to add the cool cream to the hot coffee or to let the black coffee cool down first and then add the cream. (ZWH)

Provides a method to help students understand problem-solving techniques used in introductory physics courses. (MVL)

Notes that when using the screw as a simple machine, the pitch of the screw is important in the amount of force that will be produced. (MVL)

Describes a study that illustrates that collaborative-thought experiments are emergent phenomena triggered by events as a whole rather than being predesigned. Points out that participants gradually adopt shared graphical representations and meanings. Contains 28 references. (DDR)

Presents a problem involving the double-slit interference pattern that relates to the real-world situation of guiding an aircraft to a safe landing. (JRH)

Provides a schematic to build a black box experiment that uses light bulbs of various intensities. The students are to determine the complex circuit by unscrewing the bulbs and noting what happens. (MVL)
