Abstract:
This investigation provides an opportunity to see and use real time data being collected by scientists who are working on the cutting edge of space science. The investigation can be tied in with Physics (kinematics, magnetism) and Earth Science content on the Sun and solar system structure, meteorology and weather prediction (in space) as it parallels that on Earth, and spacecraft and what they do. It also blends the use of teaching across the curriculum by integrating data analysis and mathematics.

Most parts of this investigation can be done as stand-alone activities, and are adaptable to a variety of learners.

In this investigation the learner will explore “space weather,” its measurements and prediction. The accompanying Educational Brief provides an explanation of space weather and its effects. The learner will explore web sites related to space weather and its resources. The learner will also access plots of real time data provided by some of the ACE instruments so the learner can draw inferences about the prediction of space weather.

There are variables and measurements that are comparable to what we find with Earth’s weather. These variables have specific definitions and will be outlined in the background section.

Outcome:

• The learner will identify space weather as a function of three areas or regions of study:
  

  1. The Sun.
  2. Space between the Sun and Earth.
  3. The Earth and its magnetosphere.
  

• The learner will use distance = velocity (rate) * time to calculate the advance warning time from a solar event.
  
• The learner will compare the speed of a proton to the speed of light
  
• The learner will identify relevant variables for discussing space weather forecasts, such as Kp, solar wind density and speed, interplanetary magnetic field strength, and voltage across the polar cap - convection potential.
  
• The learner will chart real time solar wind data.
  
• The learner will read an authentic piece of scientific literature based upon space weather as a topic.
  
• The learner will compose an original version of a fictional space weather events, set in the future, identifying important effects of a space storm.
