Lantern Moon: Electricity in primary school with physicist Otto Lührs


Everyone who swings a pocket lamp in fast circles can oberserve this phenomenon: Even though the light of the lamp only comes from one point you can see a circular line of light. But how can that be?

Otto Lührs is a physicist and electrician. As a young boy he was curious about how radio, television and telephone do work. Today he is committed at the Technic Museum in Berlin. There he is showing his own inventions to a broad audience in order to explain physical phenomena. One of these inventions he presents at ‘Lantern Moon and Hot Ears’: Students are building a disc rotography with light-emitting diodes on the record. The students observe what happens, when the record moves quickly and also learn about the components of an electric system.

The teaching brochure ‘Lantern Moon and Hot Ears’ was created by an international working group following the Science on Stage festival 2011 in Copenhagen. The new edition with simplified texts contains templates which can be copied to promote language skills with natural sciences. Scientists explain in them, how they came to their chosen profession and the sometimes odd stories thathappened to them along the way.

The collection contains assignments to promote language skills for students with various experiments. Primary school teachers working with these assignments do not need to have specialized scientific knowledge. The brochure can be downloaded here.
