Observing sun spots
Use the telescope that you made in a last experiment. Set it up so that it points directly at the sun and focus it so that a clear and bright image of the sun is formed on a piece of white cardboard placed a short distance from the eyepiece lens.

Do not look at the sun by the telescope, unless your eyes are protected by a dark glass filter.
