  1. A Year at Howard High School of Technology John D. Shaw Funded by National Science Foundation Graduate Teaching Fellows Program in K-12 Education (GK-12) DGE 0538555

  2. Our Team John Shaw Graduate Fellow + Teacher Dr. Ralph May Physics and Astronomy University of Delaware Chemistry and Integrated Science Howard High School of Technology

  3. Goals • Develop innovative methods to convey ideas and scientific method. • Emphasize universal nature of physical laws. • Emphasize data taking and analysis. • Emphasize deductive reasoning to generate predictions. • Stimulate independent thought and research.

  4. Example Projects The Rotation of the Sun A Project CLEA computer based lab adapted for use in NCCVoTech. Students observe real images of the sun and follow sunspots over several days

  5. Example Projects

  6. Example Projects • The Rotation of the Sun • Learn to take and analyze data. • Repeat observations for accuracy. • Compute synodic and sidereal rotation. • Importance of taking observing point into account. • Discover different rates of rotation depending on latitude.

  7. Example Projects The Moons of Jupiter A Project CLEA computer based lab. Students observe simulated images of the four Galilean moons of Jupiter. Measure the distances from Jupiter and periods of orbits by fitting sine curves to data. Period Maximum Distance West Period Distance from Jupiter Period Maximum Distance East 0 90 180 270 360 0 ө

  8. Example Projects The Moons of Jupiter Find mass of Jupiter by using Kepler’s Third law: Mass =(distance)3/(period)2. Extend to Earth – moon system, and other bodies in the solar system.

  9. Example Projects Scale Model of the Solar System Students calculate distances and planet/moon sizes if the Earth were 1 cm, 1 inch or 1 foot in diameter. Plot orbits on 40”x36” map of Wilmington. Determine location of planets today and plot. Compute and plot location of planets in one years time.

  10. Example Projects Scale Model of the Solar System

  11. Example Projects • Scale Model of the Solar System A Quantatative Prediction! Where a planet will be observed in the future based only on knowing how far a planet is from the sun and where it is observed to be now. 1 foot scale Earth – Orbits of Mercury, Venus and Earth

  12. Other Duties Assist with Chemistry lab experiments Observe student successes and problems with traditional studies and new projects.

  13. Conclusions Use of “hands-on” materials were most effective in conveying ideas. Greatest problems are engaging students and students’ false preconceptions. Improved my ability to better communicate scientific knowledge and my own research to a broad audience.
