Water with salt energy
 

 They needed:
The children took two glasses., a copper wire, a piece of aluminium foil and metal wire and three cables. A quarter glass of boiling water and ¼ glass of  common salt.
 
What they did:
They  twisted a piece copper wire, we folded the foil in a shape of a square. They joined one cable to a piece of  aluminum foil, and the second one to a spiral of copper wire, and then they connected them to the metal wire.
The pupils reinforced the connections with a strong tape. Then, whey repeated the whole procedure once more. Finally, They connected those two parts with the aid of the cable and metal wire, and we placed them in two separate glasses.
They made a solution of boiling water and salt. Children poured the solution into two glasses. They connected the ends of the cables to Grześ mobile phone.
 

 

Water energy

Julia brought her younger sister’s toy – a mini water turbin. She showed all the pupils how a water-power station works.

Kinetic energy

 The children  brought a racing track together with toy cars. Toy cars were then set in motion and kinetic energy was generated as a result of crashes. 

Energy which comes from noise

The children prepared drums, a membrane, which they got from a balloon stretched over a pipe, a microphone and, of course, the battery. Provided with the instruments, the pupils started playing in order to make a big noise. The membrane started vibrating as a result of the formed acoustic wave. The microphone, which was close to the pipe, picked the vibrations and transfered the generated energy onto the battery.

The solar energy

They used a model of solar battery

The vulcano energy

The pupils used a model of volcano made from cartoon and plaster, where the bottle was placed inside. Vinegar and soda were poured into the bottle which caused the volcano eruption.
