Photocopying rock slices In many cases it is advantageous for students to have photocopies of rock slices because these can be marked. It is usually helpful to have the original rock slice for students to see. Take a piece of A3 paper and put the slice on it and mark around the outside of the slice.  Now cut out the shape of the slice. First place a sheet of acetate (overhead transparency) on the photocopier and then the paper on top. Place the rock slice within the hole in the paper. If you can choose between text or photo on the machine choose the latter. Now you are ready to photocopy.  Adjusting the darkness may improve the copy.
