When these particles hit the atmosphere a shower of new, short lived particles are formed. One of these particles is the muon. In this scenario we describe how the muon flux can be measured in the classroom using muon detectors in Stockholm House of Science. These measurements can then be compared to measurements done at ISS. The importance of the Earth\'s atmosphere and magnetic field is discussed.</langstring><langstring xml:lang="sv">Jordens atmosf&amp;#228;r tr&amp;#228;ffas hela tiden av partiklar fr&amp;#229;n rymden, s.k. kosmisk str&amp;#229;lning. N&amp;#228;r dessa partiklar kolliderar med v&amp;#229;r atmosf&amp;#228;r skapas en skur av nya, kortlivade partiklar. En av dessa &amp;#228;r myonen.
