Help for science exhibition project
 
Mad scientist, plz. i need help for chosing my science project. I want help making a working model which is probably a model of eco -friendly energy, or some-thing like that, which is not VERY complicated, i am in grade 8, please help or tell me what you would prefer making.
Thanks,
Akshay :)

hmmm. "a model of eco -friendly energy"

That is something more difficult, and i am not to sure it can be easily done.

Building a solar power light might be something to consider.... or using water to collect Hydrogen.

Here is a link on how to make a solar cell.

And here is a link on how to bottle hydrogen.... i guess you could make some kind of "engine". Where the battery breaks down the water, the H and O2 are then funneled into some sort of combustion chamber and boom.

I have done that before with varying degrees of success.
Even then tho.. that is not so efficent. It takes a lot of energy to break H2O appart.... and the battery you are using will be wasted quick {9v only last about 10min.} And that can be very dangerous, as Hydrogen is very explosive. So if you do choose that make sure your parent is with you! But you can run a small "engine" off water. But there is a lot of trial and error with this to....

Hope that helps some :)
If that seems to be no help... tell me and I will try to come up with an idea.

Thanks, but onemore thing...
 
Thanks for the reply, and i guess the links u gave were a little complicated, and i am in grade 8 and don't know much about ampere and solar currents, etc. I guess i would ask you to give me something more simpler and on a topic which u would prefer. I would appreciate if u reply.
Thanks,
Akshay

Energy Science Project
 
thanks Archenemy for your always excellent suggestions! You're the best!

Akshay, try going to [url]http://www.all-science-fair-projects.com/science_fair_projects.php?s_terms=energy+generator &type=0&s_difficulty=2&hidden=1&s_category=[/url]
to see if any of the projects are suitable for you. If not, let us know and we will try to see what else we can do for you!

Truly Madly Yours :eek:

ecosystem
 
I've seen these bowls with fish and live plants that illustrate an ecosystem. It shows how solar energy (from the sun) allows the plants to grow, and then the fish eat the plants. Then there is of course the cycling of the gases -- the plants take up carbon dioxide and release oxygen, and the fish take up oxygen and release carbon dioxide.

you need a project on energy so why not do one on solar energy which is the rage today.
you can eve make a simple working model of a solar cooker, water heater, furnace or if you try a solar cell.

you can even make a model of a wind mill to generate electricity and i think you'll find all this on the all-science-fair-projects search engine.
all the best.....

Great suggestion!
 
Thanks for the good advice! :)

just trying to help
 
hi everyone well I did a same thing I did for eco friendly the hypot was: which liquid helps plants to grow better. I used: salt water, saugar water, tap water, bottle spring water, rain water and milk...

hope it helps :)
do tell us how it goes ;)
