Plain flour has a lot of chemical energy packed into it. When the flour is in a clump or pile it does not ignite although it may blacken. This is because there is not enough flour exposed to the oxygen in the air. Aerosolising the flour exposes it to much more oxygen allowing a self sustaining combustion reaction to occur when an ignition source…

We describe a third-year undergraduate course that focuses on multiscale modeling and protein folding and has as its primary goal the encouragement of students to integrate thinking across and beyond disciplinary boundaries. The ability to perform innovative and successful research work in STEM (science, technology, engineering, and mathematics)…

This article describes a lesson taught in a designated English Language Learner (ELL) classroom in an elementary school in Pawtucket, Rhode Island, using a sheltered instruction approach. Eighty one percent of the students at this school are from diverse ethnic backgrounds where 25 per cent of them receive ELL services. A variety of languages are…

Wind is reemerging as a clean and reliable source of energy--primarily for the production of electricity. This article discusses how to create a pinwheel to explore wind power. It presents a 5E learning-cycle lesson in which students construct a simple pinwheel-type windmill to test the power generated by different designs. Students compare three-…

Invention activities challenge students to tackle problems that superficially appear unrelated to the course material but illustrate underlying fundamental concepts that are fundamental to material that will be presented. During our invention activities in a first-year biology class, students were presented with problems that are parallel to those…

In this paper, we discuss our approach in teaching the final-year course Process Systems Engineering. Students are given ownership of the course by transferring to them the responsibility of learning. A project-based group environment stimulates learning while solving a real engineering problem. We discuss postgraduate student involvement and how…

Educational robotics activities are gaining in popularity. Though some research data suggest that educational robotics can be an effective approach in teaching mathematics, science, and engineering, research is needed to generate the best practices and strategies for designing these learning environments. Existing robotics activities typically do…

Describes an approach to teaching engineering design that involves analyzing, designing, building, and testing a simple structure. Explains the procedures for the various activities and discusses how the design concept can be incorporated into other courses. (ML)

Usually the textbook descriptions of analytical methods fall short of making comparisons among several methods employed for analysis. Emphasis should be placed on making decisions about using a particular method on the basis of its merits. Listed are experiments that could be used for instruction. (PS)

Explores the use of extra credit in an introductory geology course. Covers the organization and rational behind the program. (PR)

Discusses the development of a one-year laboratory course in an effort to provide a link between traditional laboratories devoted to a single area of chemistry and the total involvement of a single narrow research project. Included are outlines of 32-hour lectures and 11 experiments performed in the integrated course. (CC)

Two linked courses examining conservation science and art history of 17th-century Dutch painting are described. The two courses have been taught on campus and, most recently, as study-abroad courses in collaboration with the Center for European Studies, Universiteit Maastricht, The Netherlands. The highly interdisciplinary courses are intense, yet…

Describes an elementary science methods course at Eastern Illinois University designed to interest pre-service elementary teachers in the process of science. Instead of a traditional final examination, students select an open-ended problem and report the results of their investigations. Fifty sample research problems are listed. (JR)
