An Activity using Images of the Jupiter Project

• Naoki Matsumoto
• Keio Senior High School
• and JAHOU,HOU members

2
Ordinary Activity of Keplers Law

• To use Mars position data from moving Earth for
  to draw Mars orbit.
• ? Complicated (Yakkai in Japanese)
• Using mini solar system (Jupiter system)
• ?Using Jupiter project images.

3
The Jupiter Project

• July 2000Global HOU Conference in Germany,Munich
• This Project was proposed by Faye(France).
• An international joint observation project for
  education.
• The sleepless observation network for Jupiter and
  its satellites.

4
The Jupiter Project 2000

• 2000/12/17
• Participants from Germany, Finland, Sweden,
  France, USA, and Japan
• 336 images were taken by this term.

5
The Jupiter Project 20024

• Construction the environment what students can
  participate in.
• Making observation managing system on web.
• Managed by students.
• Images were taken in .2002 129 images2003 207
  images 2004 773 images

An Activity using the Jupiter Project Images

• Purpose
• Understanding Kepler's law intuitively.
• Deciding mass of Jupiter using images taken in
  Jupiter Project.
• Increasing a sense of closeness by using images
  taken by high school students.
• Object of the activity
• Earth Science for 10th Grade

7
Work book

• Making workbook using
• Web Browser

• Images were taken by Toyo-oka HS, Toko science
  and technology HS, Bisei Observatory (Bisei
  Junior High School), Yakes Observatory, and Keio
  HS.

Procedure of activity

• Download worksheet (Excel) from server.
• Measuring distance from center of Jupiter to each
  satellites on 13 images.
• Pictures in classroom
• Making Graph using Excel.
• Excel File

By Bisei Junior High School
9
Rotation and Oscillation

• Rotation ? Viewpoint switch ? Simple oscillation
• Simple oscillation Time ? sin curve
• Sin curve ? ?Radius of orbit ?Revolution
  period

Finding from the Graph
Questions on worksheet ?Draw the change of the
position when you watched the revolving body from
the front direction. ?Mark the radius of orbit
and the revolution period by red arrow

Calculation of Jupiters Mass

• ?Radius of orbit ? a (m)
• ?Revolution period ? P(sec)

?Jupiters Mass
15
Result of students
Right value 1026,1027
16
Understanding of Keplers law

• Relation of a and PInner satellite(a Small)
  ? Fast (P Short)Outer
  satellite(a Big) ? Slow (P
  Long)
• Almost students showed this relation correctly.

• This shows that Kepler's 2nd and 3rd law were
  understood.

17
The impression of the students 1

• ABOUT Calculation of Jupiters mass
• The way of the experiment is a doubtful method
  which measure distance between the stars on the
  images with a ruler. However, I was surprised
  though a proper result was provided.
• I was surprised to be able to calculate mass of
  the Jupiter by such a simple data.
• I was complicated, but was interesting.

18
The impression of the students 2

• ABOUT the Jupiter Project
• I felt reality. Because I used the real
  photographs.
• I think it is very good idea which decide mass of
  Jupiter from the images taken around the world.
• I want to join this observation project.

19
Conclusion

• I developed an activity that using the Jupiter
  Project images and carry it out.
• It includes difficult subject, however it was
  interested in students.
• It contributed to understanding of the Kepler's
  law.
• The images which were taken by same generation
  students, led reality and closeness.
