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

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.

8
Example Projects
  • The Moons of Jupiter
  • Find mass of Jupiter by using Keplers 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 40x36 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.
