This learning module uses the Blender Tool to compare images of the plane of the Milky Way in fourteen different wavelengths. The student uses the blender to load a different wavelength into each of the three color components (red, green & blue). The resulting image can be manipulated in order to display the similarities and differences of various images. The student works through a problem tree which asks questions about specific images.

This problem, in its entirety (including the problem tree and the blender tools) is available here.

The Python script of the problem tree for this exercise is available.
