Ok so I wasn't the smartest cookie, and I blew this project's "proposal" off until tonight which is due tomorrow. Any who, I have to have 3 topics about stupid possible topics :mad:. And I can only think of one.

• Evaporation
• Get three glasses
• Fill each one up with water
• One having 5 table spoons of salt
• Another having 10
• See which one evaporates fastest

That is all that I can think of, I know that you guys are not homework hot line help. But I'm stumped >.<. All I need is a topic and a possible experiment, I'm not looking to be the best in the class, just to get a good grade. Oh and they have to be Earth Systems related. Like no paper airplanes… lol.

Thanks!!! :cool:

Acidic properties of vinegar:::: pH::::::Chemistry
submerge and egg in vinegar for a few days (until shell is soft)
conclude that the vinegar (aka acetic acid) dissolved the calcium components of the egg shell. For the control, put an egg in a glass with distilled water (or tap if you aren't needing to be that precise)

Lol, thanks I'll see what my teacher says.

could you possibly define "Earth Systems" for me?

Sorry, I guess I should have already done that.

• Unit 1 - Earth Science
• Unit 2 - Composition of Earth
• Unit 3 - Surface processes on Earth
• Unit 4 - The atmosphere and oceans
• Unit 5 - The Dynamic Earth

If that helps at all the four "earth systems" are the litosphere, hydrosphere, atmosphere, and biosphere as defined in the book.

how bout condensation:
look at the mirror when you get out of a hot shower
or put a cool mirror over a pot of boiling water

Oo, that doesn't sound half bad. Thanks!

dry ice - sublimation :p (solid to gas)

lol any others? :D

diffusion through a gas

spray a squirt of air freshener in a still room and see how far the scent goes
(or fart in a still room, and see how far it goes :p)

Hahahaha that made me laugh, how would I measure that though, just guess? And I think we might be getting a little off the topic haha

spray the bottle straight up for 3 seconds or something

have people stand 5 feet, 10 feet, 15 feet, 20 feet…….away, and see how long it take for them to smell it/if they smell it. It should smell the strongest closest to the source, and weaker as it moves out.

try to minimize movements, and make sure the furnace or something does not turn on. See how far the scent goes, through still air. How does it move if there is no air current? it diffuses.

Okay, i'll write that one down, thank you very much Brain!!!

EDIT: Wrote "Brian" instead of "Brain" Brian is my name >.>

you're welcome

He comes in useful for somethings :p

How did the teacher like your ideas?
(whenever you get back)

record the average amount of smoke released from a cigarette smoker in a day.
then record again but this time with a joint smoker, or pipe smoker/bong smoker… record which one is adding more smoke into the air. congrats lols. I am just joking lols. Not sure… i have done enough geology at school… its on to biology for me.

@brain we handed in the "proposal" (what i needed the ideas for) friday so i'll get back to you on monday :P if you hands them back

From: All that is man

Dam, i was too late.

Well, i dont know if this is considered ' Earth Systems ' but its dam cool.

Put some of that windshield wiper fluid in a water gun, hold a lit match under the tip of where the water(fluid) sprays out, and youve got your self a flame thrower :)

Lmfao you made me lol'd so hard, no that's not earth systems thanks though!

@brain we STILL haven't gotten it back yet…
