Star+Classification

 =Star Classification = I like to use this activity before we talk about star types. The students work in groups and arrange the stars according to their choice of property. They make some observations about their arrangement, then choose another property. After they have done this several times, there are questions and their very own special H-R diagram to plot the stars.

I run the stars on different color paper (indicated on the pages in the document), then laminate them and cut them out.  (This is not original with me. I found the activity on [|middleschoolscience.com]  and put it in a format I like)
