  • investigating sea level rise due to global warming in the teaching laboratory using Archimedes Principle
    Institute for Future Environments; Science & Engineering Faculty, 2015
    Co-Authors: Stephen W Hughes, Darren Pearce

    Abstract:

    A teaching laboratory experiment is described that uses ArchimedesPrinciple to precisely investigate the effect of global warming on the oceans. A large component of sea level rise is due to the increase in the volume of water due to the decrease in water density with increasing temperature. Water close to 0 °C is placed in a beaker and a glass marble hung from an electronic balance immersed in the water. As the water warms, the weight of the marble increases as the water is less buoyant due to the decrease in density. In the experiment performed in this paper a balance with a precision of 0.1 mg was used with a marble 40.0 cm3 and mass of 99.3 g, yielding water density measurements with an average error of -0.008 ± 0.011%.

  • a technique for fast and accurate measurement of hand volumes using Archimedes Principle
    Australasian Physical & Engineering Sciences in Medicine, 2008
    Co-Authors: Stephen W Hughes, Jaclyn Lau

    Abstract:

    A new technique for measuring hand volumes using Archimedes Principle is described. The technique involves the immersion of a hand in a water container placed on an electronic balance. The volume is given by the change in weight divided by the density of water. This technique was compared with the more conventional technique of immersing an object in a container with an overflow spout and collecting and weighing the volume of overflow water. The hand volume of two subjects was measured. Hand volumes were 494±6 ml and 312±7 ml for the immersion method and 476±14 ml and 302±8 ml for the overflow method for the two subjects respectively. Using plastic test objects, the mean difference between the actual and measured volume was -0.3% and 2.0% for the immersion and overflow techniques respectively. This study shows that hand volumes can be obtained more quickly than the overflow method. The technique could find an application in clinics where frequent hand volumes are required.

  • developing and evaluating physics teaching material with algodoo phun in virtual environment Archimedes Principle
    International Journal of Innovation in Science and Mathematics Education, 2015
    Co-Authors: Harun Celik, Ugur Sari, Untung Nugroho Harwanto

    Abstract:

    This study examines pre-service science teachers’ perception on computer-based learning (CBL) experiences through virtual physics program. An Algodoo program and smart board was used in this study in order to realize the virtual environment. We took one specific physic topic for the 10th grade according to the physics curriculum in Turkey. Archimedes` Principle is one of the most important and fundamental concepts needed in the study of fluid mechanics. We decided to design a simple virtual simulation in Algodoo in order to explain the ArchimedesPrinciple easier and enjoyable. Smart board was used in order to make virtual demonstration in front the students without any real experiment. There were 37 participants in this study who are studying pedagogical proficiency at Kirikkale University, Faculty of Education in Turkey. Case study method was used and the data was collected by the researchers. The questionnaire consists of 28 items and 2open-ended questions that had been developed by Akbulut, Akdeniz & Dincer (2008). The questionnaire was used to find out the teachers`perceptions toward Algodoo for explaining the ArchimedesPrinciples. The result of this research recommends that using Algodoo program in physics teaching has positive impact and can improve the students’ understanding.
