Solar Light Bulbs
Our class did a Science
Project learning to use sun and water - but not money!
First, we got some boxes
(we recycled the boxes our AMCO English books come in!) and full bottles of
water, and each group painted their box with very colourful colours.
Next, we cut a square from
the top of the box and cut a circle out of this square. We glued the new shape
back onto the top of the box.
Then, we pushed half the
water bottle into the hole (on the top of the box), holding the piece we cut
off, so that the bottle wouldn´t fall.
Finally, we cut a little
door in the side so that we could see light inside the box without light bulbs.
We took the boxes outside
and tested how much light was inside the box by covering the top half of the
bottle and looking through our mini door. It was very dark and difficult to see
anything. But when the cover was taken off the bottle and the sunlight shone
into the water, it refracted down into the bottle and inside the box was bright
with sunlight!!
It's a fantastic idea! And
in poor places they do this project in the roofs of their houses and they have
solar light bulbs.
And all this, with only a
box, a full bottle of water (and colours if you want to make it beautiful!!)
