Creating a solar oven publié le 22/03/2009
Najprej smo sončno peč poskusili narediti brez učiteljev. To smo delali tako, da je vsak sam naredil svojo maketo peči. V dveh urah nam je uspelo narediti različne makete sončne peči, kakor se nam je zdelo najboljše.
Potem smo se z učiteljem fizike, g. Staretom, odločili, katera peč je najbolj primerna in se lotili dela.
Naredili smo nekakšen načrt in se zmenili za mere. Zbrali smo material, ter začeli izrezovati posamezne dele peči. Ko smo naredili vse dele, smo jo sestavili in jo poskusili, tako da smo preverili njen odsev sonca s pomočjo laserja.
A SOLAR OVEN
First, we tried to make a model of a solar oven without our teachers. We tried to make different models. In two hours each of us managed to prepare the model as we thought it would be best.
Then, together with our Physics teacher, Mr Stare, we decided which model of the solar oven would be the most suitable and set to work.
We drew a plan and thought of the measures. We collected the material and began cutting out the individual parts of the solar oven. When all the parts were prepared, we put them together, and then we tried to check the reflection of the sun with the help of a laser beam.
We used a box and covered it with an aluminium paper. The box was big enough to put a pan inside it. After the covering with the aluminium paper we tested the oven by exposing it to the sunrays and we also used a little cuisine thermometer to know the inside temperature. We realized that the temperature was high enough to cook small quantities or to warm dishes already cooked.
