On 11th and 12th May 2017 the teachers of our school together with students from class 2a and 2b took part in physics show organised by Rzeszow Polytechnics . It was the second time we participated in thie event. This year the experiments were also presented by the workers of the Polytechnics : Tadeusz Jasiński, Jan Mamczur, Krzysztof Kiszczak, Paweł Wnuk and Tomasz Więcek. We were amazed with the presentations as all of them were completely different ones then the ones we saw last year. 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 .
