that a fresh water ice would float higher in fresh water then salt water? I know this is confussing but, i'm doing a science project, and my teacher says that hypothosis are normally wrong, so i want mine to be wrong. Any sciencetific reasons why fresh water ice would have more above the surface than in salt water?

There is absolutely no reason to think fresh-water ice would float higher in pure water than salt water.
That being said -- you should never choose a hypothesis that you believe is wrong. That is completely pointless. If you believe the hypothesis is wrong then why are you doing the experiment? I can't imagine why your teacher is telling you that most hypotheses (by the way, hypotheses is the plural of hypothesis) are wrong... That's misleading at best, and I'm not sure that it's even true.
Still, you should go with the hypothesis you think is correct. The experiment should either support or refute that hypothesis, and you can then write a lab report on it based on the results. Whether or not the hypothesis seems obvious is not important at all. You should always use a hypothesis that you believe will increase knowledge on the subject. I'm sure many young people would have no clue as to whether fresh-water ice would float higher in fresh/salt water... This is a great experiment, no reason to mess things up by choosing a hypothesis you believe is incorrect.

Science works by proposing hypotheses and then testing them. The hypothesis is that ice floats higher in salt water than in fresh water. You can test it by careful observation, you can test it by mathematics using specific gravity. If your hypothesis is correct, great, you have discovered something you didn't know before. If it is incorrect you have also learned something.
By the way, science does not deal in beliefs. It deals in evidence. If ice does not float higher in salt water, believing it does will not make it so.

Fresh water ice will float higher on salt water because salt water is denser. Though if the ice is made of salt water it will float normally in salt water.

first of all, don't try to make your hypothesis wrong, not all are wrong, and if it is right, you look smarter. for the ice, the density of salt water is greater than that of fresh water, so ice will float higher in salt water

you shouldn't manipulate your experiment. just make a hypothesis and stick with it. and i wouldn't say that most hypothesis are wrong. .
salt water is denser, so fresh water ice would float higher in salt water than in fresh water.

Tell me why you get fresh water on ice from salty water instead of salty water when the salty ice is melting. then test it out.

This is density.Fresh water ice means pure water.There is salty water.

Sorry can't help you... i don't know either

dude... the thing about density, duh. Do your own science project, smoke some pot and reeeeeeeelax.
