Abstract:

This investigation provides an opportunity for the learner to access some real-time Advanced Composition Explorer (ACE) spacecraft data. The ACE/SWEPAM data plots they will access will be used to determine temperature and radial speed for the solar wind. In addition, the learner will use a variety of information about the ACE spacecraft to solve sample physics problems dealing with conversion factors, kinematics, mass/weight, momentum, and work/power/energy. In the investigation the learner is provided with the appropriate physics equations and conversion factors and is asked to solve the problems. The problem sets could be used:

• throughout a physics course to introduce students to some specifics about the ACE mission
  
• to provide supplemental problems to be used while studying the topics listed above
  
• as a review set for a final exam in physics.
  
  

There are two accompanying Educational Briefs. The first provides an explanation of basic atomic structure and explains the ACE project. It is the

Outcome:

• The learner will access some ACE real-time SWEPAM data plots to determine temperature and radial speed for the solar wind and answer associated questions.
  
• The learner will be able to list instances where their physics curriculum relates directly to work being done by scientists who are working on the cutting edge of space science.
  
• The learner will be able to solve physics problems dealing with conversion factors, kinematics, mass/weight, momentum, and work/power/energy
  

Suggested Grade Level & Duration:
Grades 9-12; 1 to 2 fifty-minute periods.

Materials:
The learner will need a computer with internet access, a scientific calculator, and an attached printer (to print a copy of the procedure for the investigation if so desired).
