projectes 1r A Institut Joan Oró

On the fifth of March 2014, we went to the technology workshop. It was time for “Scientists in action”:

We did four difference experiments:

The first one: Electricity using a chemical reaction. The chemical reaction with the iron or copper make electric charges and then make electricity.

The second one: Electricity using photovoltaic panels .The photovoltaic panels have electrons and when the sunlight impacts with the electrons of the photovoltaic panels, they move and generate electricity.

The third one :Electricity using electromagnetic method. We used a magnet and a wire that have electrons. We moved the magnet up and down. The electrons move and generate electricity.

And the fourth one: Electricity using the piezoelectric method. There is a little hammer that when we click on that, a spark goes out and it makes an electric impulse
