	Science project NEED ADVICE ASAP
fishrneat Fingerling Posts: 34 Votes: 0 Registered: 02-Mar-2005	I am doing an experiment in my Science class involving freshwater or saltwater specimens. My Ideas were: SALTWATER Hermitcrabs Fiddlercrabs FRESHWATER Snails possible Dwarf African Frogs I need an idea for an experiment not using food for the saltwater specimens ideas already were: how do they react to ________________________ (not sure about what to put in the blank thats where i need help) PLEASE HELP fishrneat Last edited by fishrneat at 21-Mar-2005 15:25

fishrneat Fingerling Posts: 34 Votes: 0 Registered: 02-Mar-2005	I thought about polution after you said it but i wouldnt want to harm the little critters

littlemousling Conchiform Posts: 5230 Registered: 23-Aug-2003	With snails, I think it's be interesting to look at a population graph - put the same number of snails in identical containers but feed the first tank one pellet per day, the second two, etc. The additional food will allow for the survival of additional snails and the population will increase (you should probably count them based on a certain shell size, ie how many snails are there in the tank which are .5" long?), but at what point will the pollution caused by the food curtail population growth? Could make for some very interesting charts, and of course you'd take nitrate readings as well as shell numbers. -Molly Visit shelldwellers.com!

fishrneat Fingerling Posts: 34 Votes: 0 Registered: 02-Mar-2005	OH YEAH , I forgot I have a very picky science teacher and need to perform trials for a week. So it would have to involve trials. Really sorry, Fishrneat

littlemousling Conchiform Posts: 5230 Registered: 23-Aug-2003	What do you mean by trials, exactly? Trials of what? -Molly Visit shelldwellers.com!

fishrneat Fingerling Posts: 34 Votes: 0 Registered: 02-Mar-2005	Trials meaning each day test something

littlemousling Conchiform Posts: 5230 Registered: 23-Aug-2003	Right - so test nitrates, check number of snails, maybe phosphates. -Molly Visit shelldwellers.com!

fishrneat Fingerling Posts: 34 Votes: 0 Registered: 02-Mar-2005	so my problem could be How does the population of snails change the level of nitrates in a small aquarium? But how do you test nitrates and what kind of pelets do snails eat?

pugperson Fish Addict Posts: 877 Kudos: 953 Votes: 293 Registered: 16-May-2003	There maybe special snail food, but dropping in an algae wafer or shrimp pellets would be something you could control. I think most snails will eat just about anything.

Megil TelZeke Fish Addict Posts: 863 Kudos: 890 Votes: 393 Registered: 21-Jul-2003	well you could test for several things. the impact of food availability and pollution on population size and growth. depending on what type f experiment this has to be u could even test different species of snails to determine hardiness and water parameter range. (i.e. some species of snails can tolerate minimal pollution where as others can withstand extremely high and dangerous levels of pollution.)

Shannen Banned Posts: 1160 Kudos: 1686 Votes: 98 Registered: 17-Feb-2004	I would like to see an experiment on stunting. Get 2 3 inch Oscars put one in a 55 and the other in a 29. See what the effects are. I'm guessing that the one in the 55 will grow faster. I've thought about doing this just to see what I get. But at my house tank realistate is at a premium. You could test for nitrates on a daily basis to keep your teacher happy. Given the expense of this I doubt anyone here will test this. Just my 2 cents.

Megil TelZeke Fish Addict Posts: 863 Kudos: 890 Votes: 393 Registered: 21-Jul-2003	Oh yes fishrneat revealed in chat that the experiment must occur within a week. that greatly limits all population and growth of most multicellular organisms.
