Zooniverse has several different astronomy research projects any amateur astronomy, with no initial experience, can become involved with. These projects range from galaxy classification to planet hunting to solar storm watching and more!
Each possible project requires no prior astronomical experience. Within the project page are tutorials and test examples to get you started. I highly encourage all parents to point Zooniverse out to their kids, regardless of age. Younger kids will need more assistance obviously, but you can still introduce them to the world of real astronomical research!
