If football captures the interest of students, it can be used to teach physics. In this case, a Beckham free-kick can be used to introduce concepts such as drag, the Bernoulli principle, Reynolds number, and the Magnus effect by asking the simple question: How does he curve the ball so much? Introduces basic mechanics along the way. (Author/ASK)

Uses interactive science and technology centers as an example of the application of Heidegger's ideas about technology. Discuses Heidegger's concerns about uncritical acceptance of technology. (Contains 27 references.) (SK)

Introduces a science activity on the bonding of chemical compounds. Assigns students the role of either a cation or anion and asks them to write the ions they may bond with. Assesses students' understanding of charge, bonding, and other concepts. (YDS)

Describes a lesson plan for teachers of grades 2-8 to build a capillary action water clock. Includes a list of objectives, a list of skills/concepts addressed, a rationale for inclusion in the curriculum, and an illustrated lesson outline. (Author/MM)

Describes an inquiry-based biochemistry activity on the industrial applications of cellulase, which is known as biostoning, and used to soften denim jeans. (YDS)

Describes a paternity simulation experiment with two situations. Uses ABO blood group analysis and horizontal agarose electrophoresis to identify the biological fathers. (YDS)

Presents two activities. In the first activity, students investigate a question that they choose on one of the selected toys. In the second activity, students keep journals on their experiences during the investigations. (YDS)

Introduces a scientific mystery story problem on the chemical and physical properties of metals involving characters Sherlock Holmes and Dr. Watson. (YDS)

Presents an exercise designed as a team building experience for managers that can be used to demonstrate to science students the potential benefit of group decision-making. Involves the ranking of options for surviving a large earthquake. Yields quantitative measures of individual student knowledge and how well the groups function. (Author/YDS)

Describes an activity that can be used to help middle and secondary school students develop more informed understandings of some important aspects of the nature of science in the context of teaching Rutherford's experiments and atomic structure. (Author/MM)

Explains the limitations of a traditional density experiment and presents an inquiry-based laboratory experiment which allows students to develop an understanding on the relationship between the object's properties and the volume of water the object displaces. (YDS)

Investigates a number of virtual experiences and creates three categories: (1) virtual field trips; (2) virtual digs; and (3) field trips incorporating virtual reality. (Author/MM)

Advances six practical suggestions in transpiration whereby teachers can support students in their struggle to put their thoughts, especially everyday mental models, in accordance with classroom experimental evidence. Discusses the wider implications for how to teach about living things and how to view the status of analogies in science generally.…

A compact disc (CD) serves as a diffraction grating for the study of the dependence of angles of diffracted beams on that of the incident beam from a laser. The demonstration/experiment illustrates the occurrence of different orders of diffraction. Knowledge of the wavelength of the laser permits determination of the groove spacing within ~1% by…

Describes an investigation into the photosynthetic potential of the different developmental stages of the green unicellular alga Haematococcus pluvialis. Reviews the biotechnological applications of astaxanthin, the red pigment which can be extracted from Haematococcus pluvialis. (Author/MM)
