estufas solares



A new club for girls has been formed. We are focusing on the environment- studying the Bible to see what it has to say about creation and doing hands-on activities as well, such as today's attempt to make a solar stove.
The stove is made using two cardboard boxes, tin foil, and black paint. The boxes are places one inside the other. Both are lines with tin foil (shown in the picture above) and the outside box is painted black. A lid is made in a similar way and a flap is cut on the top (the lid is being painted in the picture below). A piece of glass (or a Reynold's oven bag, if such thing could be found here) is placed over the opening of the lid, so that light can be reflected from the inside of the flap into the box. We will attempt to cook rice in the box on Thursday to see if it actually works.

so is that like a eco- version of the EasyBake oven?? Hope it worked!

It got up to 180 degrees Farhenheit today!
I think we need to do some modifications to get it to boil- it has been suggested we put cardboard wings on it and paint them black so it catches more sunlight. And it seems that you need a really clear day, because every time a cloud rolls by the temperature goes down.

Wow, that would be really cool in so many ways for so many people if you can get it to work!

We modified it this week, so it now has wings on it. We'll give it a try next Tuesday to see if it captures more sunlight this way and perhaps will boil.
