Experimenting is an important part of studying,
possibly THE most important part, and science projects on solar energy
can be very simple to do.
With the increasing awareness of environmentally friendly sources of
energy, or more particularly, the damage that is being done by the use of
fossil fuels such as oil and gas, solar energy science projects are being
welcomed by teachers as a great way to make younger people more
responsible for the health of their planet.
Simple science projects on solar energy might include the
following:
Building your own solar panel is another great idea, but will cost a
little more money. You could buy photo-voltaic (or PV) cells quite
inexpensively online, from Amazon.com or ebay.com.
There are several grades of quality, but it's best to keep costs down
by purchasing the least expensive, which is most likely going to be the
poorest quality. Of course, for science projects on solar energy this
doesn't matter, because it's not a problem if it doesn't last very long
due to its lack of durability. It only has to last long enough to present
it.

Building a solar powered oven using the same principles as when the
interior of a car gets very hot on a sunny day.
Showing how solar energy can extract water from the ground by
evaporation, by digging a hole in moist earth, putting a cup in it and
then covering it with a clear polythene sheet with a pebble on the sheet
above the cup.
More solar energy science projects might include using a magnifying
glass to heat water in something, such as water in a thimble. Don't let
your children get carried away with the magnifying glass though, because
they CAN make things catch fire of course.
A simpler version of this using almost no equipment other than two
cups of water is put these outside, one in direct sunlight and one in the
shade. After about half and hour, it becomes clear that the water in the
shaded cup is not anything like as hot as the one in the sunshine.
Depending on your child's age, determines what level of solar energy
science projects should be used. For example, what might be very
interesting for children (and the teachers who will grade them!) in grade
7 won't be the same for those in second grade.
There are lots of amazing experiments that can be put together will
little cost, and sometimes these are far more interesting for both
children and teachers alike than the ones that cost you a lot of
money.
The key to getting this right should be a balance between pure science
and great presentation. The science part is easy, and the only way you
can get your child to present it well is to make sure that THEY really
like the subject.
That way, their very enthusiasm will win over both their classmates
and teachers.
