Of the most universal applications in integral calculus are those involved with finding volumes of solids of revolution. These profound problems are typically taught with traditional approaches of the disk and shell methods, after which most calculus curriculums will additionally cover arc length and surfaces of revolution. Even in these visibly…

With crosscutting concepts such as stability and change in the "Next Generation Science Standards," this article was written for those who have wondered how to teach these concepts in a way that is relevant to students. In this investigation, students ask the question, "Why is the pond dirty?" As students investigate the health…

In this article, the author presents three different tasks that can be used to assess students' understanding of the concept of length. Three important measurement concepts for students to understand are transitive reasoning, use of identical units, and iteration. In any teaching and learning process it is important to acknowledge students'…

Discover the treasure of learning activities in your daily paper. This 20-cent text has resources for teaching reading, language arts, mathematics, science, social studies, art, career education, and local history. (Editor)

Describes a method used to teach the concept of radiometric dating using mathematical equations. Explores the lack of information in textbooks on how to solve radiometric dating problems using mathematical concepts. (SAH)

Presents the equations of motion governing the trajectory of a cricket ball subject to a linear drag force. Uses a perturbation expansion technique to solve the resulting trajectory equation for the range of a cricket ball struck into the outfield. (Author/ASK)

Presents methods for estimating running speed, length of a broad-jump, height of a pole vault, and time to run up a flight of steps as examples of elementary numerical mechanics. (SL)

This article describes a demonstration in which a straightened coathanger supported by threads and held near the ears resembles bells or gongs when struck. A mathematical explanation of the effect is provided. (MVL)

Described is a team assignment where groups of students work on stoichiometry problems that apply to the real world. Teams of students act as chemical companies that have orders to fill for a customer. Included are the details of the customer order, student participation, and the evaluation procedure. (KR)

Presents the following activities for teaching elementary students about the metric system: Metric Soda Fountain, Metric Meals, Metric Moola, and Metric Golf. (PR)

Water rockets are used to present Newton's three laws of motion to high school physics students. Described is an outdoor activity which uses four students per group. Provides a launch data sheet to record height, angle of elevation, amount of water used, and launch number. (MVL)

Describes a summer program for prefreshman science students entering Xavier University, designed to develop their problem-solving and academic abilities by emphasizing the connection between reading comprehension and analytical skills. (MKM)

Discusses the use of computers in chemistry courses at the United States Military Academy. Provides two examples of computer projects: (1) equations of state, and (2) solving for molar volume. Presents BASIC and PASCAL listings for the second project. Lists 10 applications for physical chemistry. (MVL)

Describes the learning style inventory and learning cycle developed by David Kolb. Discusses the learning cycle's four stages as concrete experience, reflective observation, abstract conceptualization, and active experimentation. Offers an example from a chemical engineering class in which Kolb's ideas are used in an effort to improve instruction.…

Provides a rationale for a learning environment in science classrooms that integrates science, mathematics, and technology while solving authentic problems. Describes activities that can be used in such an environment and presents data regarding students' attitudes toward the described activities. (MDH)
