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…

The NGSS MS-ETS1 Engineering Design (1-4) is the focus of the article. Development of a challenging problem-based activity that is an improvement over the traditional egg drop competition is emphasized. Quantification of data collected and real-world relevance are two activity components that are viewed as improvements over the egg drop. The…

The power of 3D printing technology has grown exponentially in just the past few years--people around the world are using 3D printers to prepare food, create tailored clothing, build cars and homes, and advance the medical field in ways that never seemed possible. In classrooms across the nation, 3D printers have become increasingly common because…

This column presents ideas and techniques to enhance your science teaching. This month's issue shares information about a unit promoting scientific literacy and the engineering design process. The integration of engineering with scientific practices in K-12 education can promote creativity, hands-on learning, and an improvement in students'…

This article presents a science, technology, engineering, and mathematics (STEM) activity, building an air cannon, in a mathematics classroom. It describes an investigation grounded in STEM concepts that elementary and middle school teachers carried out to think about ways of implementing STEM activities into their instruction. This particular…

Presents a hurricane evacuation project in which students use reading, math, and problem solving skills while engaging in a hands-on multitask problem. (YDS)

Describes the construction and use of an electrooptic apparatus that can be incorporated into the classroom to test liquid crystal displays (LCDs) and introduce students to experiments of an applied physics nature with very practical implications. Presents experiments that give students hands-on experience with technologies of current interest to…

Explains a series of laboratory activities which employ a microwave oven to help students understand word problems that relate to states of matter, collect data, and calculate and compare electrical costs to heat energy costs. (DDR)

Introduces a project of constructing a rover that can maintain its upright position with minimal gravitation that is based on National Aeronautics and Space Administration (NASA) Jet Propulsion Laboratories rover designs. Tests the project in NASA's "Vomit Comet" under zero-gravity environment. (YDS)

Describes a project that uses a multidisciplinary approach to problem solving in analyzing a crime scene and suspect evidence. Requires each student to work effectively in a team, communicate in both written and oral forms, perform hands-on laboratory manipulations, and realize that the entire class was depending on their individual contributions…

Describes how interaction with several polymer manufacturing companies through industrial short courses and research projects has led to the development of dynamic and up-to-date undergraduate and graduate curriculums in polymer science and engineering technology. (DDR)

Presents hands-on activities to teach about the causes and consequences of strokes. (YDS)

Presents two components of a piece of experimental equipment, the optical training ground and the electrical panel, which can be used to construct and test different electrical circuits and study laws of electricity, experimental problem solving, and basic light phenomena. (YDS)

Describes Controlled-Operation Mechanical Energy Transducers (COMETs), which are part of a project to introduce sophomore chemical engineering students to a number of important engineering concepts that are usually addressed later in the academic program. (DDR)

Describes the incorporation of health and safety issues into the engineering curriculum and focuses on an approach that introduces students to open-ended problems early in the curriculum. Reports that students are able to provide fresh solutions to mundane problems. (DDR)
