  1. Explorations in Physics Enhancing Scientific Literacy for Non-Science Majors w/ Real World Applications

  2. Workshop Science Project • Development of Units for the Explorations in Physics Curriculum (EiP) from 1995 - Present • Collaborative Effort • Priscilla Laws, Dickinson College • David Jackson, Dickinson College • Scott Franklin, Rochester Institute of Technology • Kerry Browne, Dickinson College • Funding • Dana Foundation • National Science Foundation • FIPSE

  3. EiP Goals • Enhance scientific literacy of non-science majors and pre-service teacher • Encourage appropriate attitudes about the process of science • Science is about making sense of the world • Emphasize inquiry over authority as the primary means of acquiring scientific knowledge • Master critical concepts in topic areas • Have positive experience w/ learning science • Learn to present results of scientific investigations • Oral • Written

  4. Achieving EiP Goals • Develop Explorations in Physics Curriculum • A set of stand alone physics-oriented interdisciplinary Curricular Units • Each unit leads students to develop an understanding of some real world phenomena • Storyline • Less material learned more deeply • EiP Units blend guided inquiry and projects • 18 class hours for structured lab-based activities and /or Interactive Lecture Demonstrations • 18 class hours for group projects recommended but not required

  5. Under Development Patterns, Fractals & Complexity Energy, Fuels & Environment Sound, Vibrations & Music Oceans, Lakes & Swimming Pools Explorations in Physics Units • Ready for Publication • Motion, Forces & Scientific Theories • Light, Sight & Rainbows • Heat, Temperature & Cloud Formation • Buoyancy, Pressure & Flight

  6. Under Development Patterns, Fractals & Complexity Energy, Fuels & Environment Sound, Vibrations & Music Oceans, Lakes & Swimming Pools Explorations in Physics Units • Ready for Publication • Motion, Forces & Scientific Theories • Light, Sight & Rainbows • Heat, Temperature & Cloud Formation • Buoyancy, Pressure & Flight

  7. Goals: Buoyancy, Pressure and Flight • To develop an experimentally verifiable model of floating and sinking. • To explore the difference between force and pressure. • To observe how gases respond to external forces. • To explore how pressure differs at various locations in air and water. • To investigate the role pressure differences play in buoyancy. • To investigate the role pressure differences play in enabling birds and airplanes to fly.

  8. Buoyancy, Pressure and Flight • Defining and measuring pushes and pulls on floaters and sinkers. • Investigating what determines whether an object floats or sinks. • Investigating pressure and how gases and liquids exert force? • Exploring how barometers and airplanes work using the concept of pressure. • Projects

  9. Buoyancy, Pressure and Flight • Measuring and defining pushes and pulls on floaters and sinkers. • Investigating what determines whether an object floats or sinks. • Investigating pressure and how gases and liquids exert force? • Exploring how barometers and airplanes work using the concept of pressure. • Projects

  10. Define floating and sinking Buoyant force measured when objects are completely submerged What Determines Buoyant Force? Size Matters!

  11. Discovering Archimedes principle • Measure the weight of the object • Out of water • In water • Measure the weight of the water displaced

  12. Buoyancy, Pressure and Flight • Measuring and defining pushes and pulls on floaters and sinkers. • Investigating what determines whether an object floats or sinks. • Investigating pressure and how gases and liquids exert force? • Exploring how barometers and airplanes work using the concept of pressure. • Projects

  13. Exploring Gases with a Syringe • Explore the behavior of a glass syringe • Tight seal • Low friction • What happens when you push or pull on the piston when you plug the end of the syringe • Identify forces on the piston

  14. Syringe Machine • Explore the connection between force, pressure and area • Kinesthetic and surprising! • Simple model for hydraulic and pneumatic systems

  15. Buoyancy, Pressure and Flight • Measuring and defining pushes and pulls on floaters and sinkers. • Investigating what determines whether an object floats or sinks. • Investigating pressure and how gases and liquids exert force? • Exploring how barometers and airplanes work using the concept of pressure. • Projects

  16. Projects: Adjusting Buoyancy • Are fish floaters or sinkers? • Students developed a model fish with controllable buoyancy

  17. Workshops • Summer Workshop • July 7-12, 2002 • Application Deadline: March 15, 2002 • Half day workshop at Summer 2002 AAPT meeting in Boise, ID • http://physics.dickinson.edu/EiPWkshp or oliver@dickinson.edu
