basically i am given an invasive species (african giant snails..they were imported to hawaii)
can any one please give me a ROUGH idea of how the following experiment could possibly be cairried out please?
how can you tEST a hypothesis (not in real life though..only for school...) that this species truly is invasive ? any CREATIVE, original brilliant ideas would be so greatly appreciated, you have no clue!!
thanks!!

So you're not actually conducting the experiment, you said "not in real life" An invasive species is something that moves in, takes over, destroys and does not benefit the habitat. Kind of like humans are to the earth. If you were to introduce this snail to an area full of the foods it likes, it would consume everything and produce nothing of value to the habitat. As snails reproduce very quickly, and are for the most part hardy, they just need to avoid a lot of direct sun, an area rich in vegetation would be in great danger of being consumed quickly by an outbreak of these snails. So you tell a story of how your blah blah plants were wiped out, then you found this population of snails, identified them and learned that they are invasive.

Maybe get a range of local vegetation and put it in a box with the snails to see if they can live on it. They cant be invasive if they cant survive on the local food

You could compare the amount of vegetation eaten by your local species, compared to the Giant African Land Snail.
You could try to explain, that due to competition, other species would die out.
You could prove it one way, by having them in seperate boxes with an amount of food, and see how much is consumed in a period of time.

they had that problem in Brazil as well. the only thing that comes to mind as an experiment to show this is to have several small ice cubes and the same number of larger ice cubes died red - or any other color for that matter. As you melt the ice cubes with a hair dryer, it will be shown how the colored ice blends in with and or powers the clear ice cubes. Best I can think of. Good luck with that.
