Where to See an Aurora
Where can you see an aurora in North America? After completing an astronomy activity, scholars can locate the exact coordinates. Pupils plot points of the inner and outer ring of the auroral oval and answer questions based on their...
PHET
CME Plotting
Young scientists build on their previous knowledge and apply it to coronal mass ejections. By plotting the path of two different coronal mass ejections, they develop an understanding of why most don't collide with Earth.
