In this article, the author describes another teacher's unique approach to teaching science in one unusual second grade classroom. Immediately upon entering the classroom, the author was surrounded by an array of colors, shapes, and objects typically found in a forest. A multitude of puppets, stuffed animals, and live animals filled the classroom.…

An extremely simple, inexpensive, and safe method is presented, which emulates nucleic acids isolation and electrophoretic analysis as performed in a research environment, in the context of a secondary school hands-on activity. The protocol is amenable to an interdisciplinary approach, taking into consideration the electrical and chemical…

Molecular biological methods, such as the polymerase chain reaction (PCR) and gel electrophoresis, are now commonly taught to students in introductory biology courses at the college and even high school levels. This often includes hands-on experience with one or more molecular techniques as part of a general biology laboratory. To assure that most…

In this descriptive case study, we describe a 10-day program of study of motion down inclined planes during which a class of 21 second graders investigated scientific relations such as mass and speed, speed and momentum, and mass and momentum via both text-based experiences ("second-hand investigations") and hands-on, materials-based experiments…

Prevention, not detection, is the best way to reduce plagiarism, the author writes. In this article he shares his own hard-won experience in coming to this view. By adopting this new view, some will regain their role as mentor teachers and will not be reduced to policers of plagiarists.

Science enquiry activities set in an industrial context are motivating for children and teachers. In this article, the author describes Children Challenging Industry (CCI) project, an initiative developed and coordinated by the Chemical Industry Education Centre at the University of York, and now running in four northern regions of England (Humber…

In this article, the authors describe their experience in extending a manual practice set to accounting software. The "Systems Understanding Aid" by Arens and Ward (2001) has been used for some time in the authors' Accounting Information Systems course. The extension involved requiring students to redo the project using Peachtree Complete…

Students in introductory chemistry classes typically appreciate seeing the connection between course content and the "real world". For this reason, we have developed a synthesis of creatine monohydrate--a popular supplement used in sports requiring short bursts of energy--for introductory organic chemistry laboratory courses. Creatine monohydrate…

We describe an inexpensive device for performing capillary electrophoresis (CE) separations with fluorescence detection. As a demonstration of the device's utility we have determined the mass of riboflavin in a commercially available dietary supplement. The device allows for separation of riboflavin in [asymptotically equivalent to] 100 s with a…

This article describes a four-year project undertaken to develop a set of performance tasks that could be used for assessing hands-on science in Irish primary schools. It begins by considering some of the literature on performance assessment and concludes with a discussion on the potential of the tasks to support teaching and learning in science.…

This study examines the development of mental models of air by kindergarten students after completing a series of hands-on, inquiry-based science lessons. The lessons focused on two properties of air: (1) that air takes up space and (2) that it is made of particles ("balls of air"). The students were interviewed about their ideas of air and about…

A soap film and bubble festival is held in order to celebrate the National Chemistry Week. The solution to make best soap solution, bubbles and wand are explained.

Toilet paper (TP) composition and physical characteristics were used to model scientific investigations that combined several "National Science Education Standards." Experiments with TP permitted the integration of TP history, societal change resulting from invention, mathematics (including geometry and statistics), germ theory, and personal…

A local middle school requested that the Water Center of Advanced Materials for Purification of Water With Systems (WaterCAMPWS), a National Science Foundation Science and Technology Center, provide an introduction to pH for their seventh-grade water-based service learning class. After sorting through a multitude of information about pH, a…

Members of a team of educators and university students participating in the project, Pittsburgh Partnership for Energizing Science in Urban Schools, addressed the issue of helping students develop investigative skills within the context of an introductory science unit for fourth graders. The unit focuses on data-collection techniques and is a…
