One of the things we designed to sell our energy to Lleida was to write a document with a lot of information about our energy. These are our digital documents.

On Thursday, boys and girls of 1st ESO went to Centre de Recerca d’Energies Alternatives (CREA) in the university. We visited the premises. First we visited the Heat pump: The heat pump is a machine that takes hot water and converts it into cold water: This cold water is used to keep the building cool.

Then we visited the room of cogeneration: The room of cogeneration compresses and burns gas, producing electricity: The waste (hot water and hot oil) is used in winter.

Next we visited the solar kitchen: The solar kitchen is made of four photovoltaic cells, two in the cooking pot and the other two in the parabolic. The cooking pot can be inside the house and the parabolic outside.

Next the photovoltaic cells: the photovoltaic cells are made of electrons. When one photovoltaic cell gets the sunlight, it spreads to the other photovoltaic cells.

Finally we visited the thermal unit:  The thermal unit is made of a lot of tubes without air inside, covered with selective cover. Inside the tubes there is a thin copper tube. Inside the copper tube there is a heat tube full of water that transports it to all the tubes.

We went to the playground to test the new solar oven that some students had built. We put some bread with cheese inside and it melt!!!!! Then with a glass dish we tried to burn a newspaper but as was not very sunny and it was a bit windy it did not burn but we saw some smoke.

Last Wednesday 1er A ESO students went to the technology classroom. There, our teacher suggested us to make a solar oven. We accepted.

Our teacher gave us the necessary material:

1. Black cardboard

2. Foil

3. Cardboard box (1 small and 1 big)

4. Newspaper balls

5. Transparent paper

First we put the small cardboard box into the big cardboard box. Then, we put the newspaper balls in the big cardboard box and  the transparent paper on  cardboard box. After that, we put  sticks to support the cover and the foil inside the box. And finally we tried it !!!

We worked on saving energy. My group made a poster of a cell phone. 

Here are all our posters!

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

First we watched an animation about the greenhouse effect. Then we worked in pairs to learn about this effect. Then we ordered some sentences about the greenhouse gases and some visuals. Finally,  we had to memorize a sentence to dub the animation we watched at the beginning of the session. And this is our recording! The greenhouse effect. Our recordings
