On 6thMay 2016 the teachers of our school Anna Pękalska, Zofia Czyżyk and Katarzyna Olszańska together with students from class 2a and 2d took part In physics show organised by Rzeszow Polytechnics . The experiments were presented by the workers of the Polytechnics : Tadeusz Jasiński, Jan Mamczur, Krzysztof Kiszczak, Paweł Wnuk and Tomasz Więcek. The meeting was connected with the topic of the changes of energy, solar power, electric current and thermodynamics. In this interesting way students could realise that energy changes all the time. One of the most interesting parts of the experiments was dealing with solar energy as renewable source of energy .
