      Hey guys what do u think about this i’m thinking about something easy i can do at home or in my backyard anyone any ideas. A project that i won’t need any microscopes or telescopes or radiology ….. there Mr. Mistery… what now 8)

      Lol, telescopes.

      Why not try growing fungus on different pH mediums?

      *bonus* use a UV light to irradiate and select for special survivors.

      Hey yah guys thanks also i have an aquarium with guppies 4 snails and 6 neon tetras. Oh I just got an idea!!!!!!!!!!!!!!!!!!!! What are the effects of different ph levels on the tank. This is a good projct because guppies like a low ph and guppies like the ph relatively neutral. Also I have all the equipment already .

      Hey guys can you help me with the project on giving me some ideas on how to make my project the best?

      thanks, locobw

      Hey guys it suppost to be a fish tank!!!!!!!!!!!!!!!!!!!!!! I just jotted that down so yah…it’s a fish tank that i’m going to do the science project on.

      You’ll kill them lol. Why don’t you try testing them for pavlovian behavior? Like maybe put a flashing light in the tank when you feed them.

    • #79352

      Yes I might kill some but not really because in one 6- gallon tank i had like 36 fish and the pH was like yellow which is like 5.0 or 4.9 or so and some of them died but the tank in all was fine.

      What’s Pavlovian behavior, and where will i get a flashing light for a fish tank? God…. you guys i can tell are a lot older than me. 😯

      To save the fish we need to find this guy a project. Put on thinking caps.

      Dude i already got a project i’m gonna do but i didn’t know killing fish that i already have wasn’t a good idea but i mean it’s science you do stuff like that.

      Ok, I got one for you. Determine the affects of electromagnetism on fish. Place a electromagnet in the center of the tank, and observe the reaction of the fish. Just be sure to not to use greasy dirty stuff to stick in the tank, afterall we do not want to kill the fish.
      Perhaps in addition you can make the same observation with just a plain magnet.
      Also consider this. I have taken it from
      http://www.apa.org/science/anguide.html

      Justification of the Research

      A. Research should be undertaken with a clear scientific purpose. There should be a reasonable expectation that the research will

      a) increase knowledge of the processes underlying the evolution, development, maintenance, alteration, control, or biological significance of behavior

      b) determine the replicability and generality of prior research

      c) increase understanding of the species under study; or

      d) provide results that benefit the health or welfare of humans or other animals.

      We also learned a similar set of guidelines in my ethics course

      one should also consider replacing higher animals with lower animals and also whether the study is redundant(duplicates previous research).

      Hey guys I got one more question what would be the purpose of the project? How does it affect the real world to put a magnet in a fish tank?

      Pleas tell me cause i think it’s pointless

      Fish seem to have the ability to perform feats of Navigation. How are they able to do this? One thing for sure is that the planet is one big magnet. Do the fish somehow sense this? I know sharks have a strong sensor for electromagnetism, the ampullae lorenzini. It was just a thought. Good question though. Maybe someone else has other ideas for a project. What is your timeline?

      Well the project is due February the 22nd.
      Also I asked the science teacher if the magnet was a good idea she said, " what if nothing happens how long will u observe it?" So i’ll email the teacher

      P.S: yah i remember last year we learned about how Birds migrate and know where norht and south are

      Hey guys this is my purpose. Tell me what you think.

      The purpose of this project is that i will see if the small magnet affects the aquarium the same way the magnetic field affects the world.I will see if their are any changes in the fish’s behavior. I will also observe if the magnet weakens and loses its electromagnetism. Another thing I will observe is if the fish have a sort of change in navigation by that I mean if they like to sleep in the front of the tank or the back of the tank. Basically I will find out if the electromagnetism from the small magnet in the fish tank act like a magnetic field.

      Also what kind of magnet should I use, like one of those kitchen magnets or like one of those really strong magnets, I was thinking the ones from the kitchen( not part of purpose)

      Try varying the field strength, that would help you confirm/disconfirm your hypothesis.

      In order to vary field strength as Mith says, you would need a electro-magnet.
      http://www.howstuffworks.com/electromagnet.htm

      As far a regular magnets. Neodymium magnets, also called rare earth magnets are the bomb. Maybe too expensive though, about 2-5 bucks. They can be found at electronic surplus stores. Maybe your teacher can help locate a source in your area for you. Here is one source for ordering online.

      I would really like to hear how this works out for you. Good luck.

      Before you set yourself on the course of this project, you should consider a couple of things.

      How are you going to measure quantitatively change in behavior? Specifically what type of changes are you measuring? In this case you might want to observe initially if there’s any sort of response before deciding on a unit of measurement.

      What if there is no change in behavior? More often than not, this would be the norm. Be prepared to answer why this is the case and what other experiments you might need to test your hypothesis.

      For example, in birds only some species such as pigeons can do this, but can all fishes? What if you used a different species of fish that also exhibits homing behavior such as salmon? You can also take a similar line of reasoning for types of magnets, and how you used the magnets.

      First off ICO, listen to Mith, He is like Mr. Wizard. Secondly I kinda thought up a test setup for you. In one test, use a fake magnet, the other test you could divide the tank with some sort of median, and put magnet on one side of median with fish on other side. Try exp with both poles of magnet. Then do same on other side of median. I made a little drawing to illustrate.

      Yah my dad said to use neodymium magnets and i know how we are going to do the project

      Hey but i’m not gonna get salmon to do the expirement i’ll just do with tetras and guppies.

      And i don’t get it how am i gonna get a unit of measurement on my observations on how i see the fish react. Also Marineland or Tetra FIn sure does not make medians for a 10 gallon tank that would be humongous and where would i get it and i sure don’t know how to make it i’ll just stick with my other idea.

      I was thinking maybe i should use different stength magnets like a N40 neodymium magnet and a N48 magnet and a regular kitchen magnet. Also i was thinking of putting a fish block between 2 magnets and see how the fish react, also I was thinking of putting food in different areas of the tank.

      P.S: FOr the median thing to work i would have to get one of those little tanks that separate the Betas from fighting and I would put 2 fish on one side. And then I would put a magnet on the other like Michael Xy said.

      Just a quick disclaimer: I never tried this experiment, and the results may prove to be less than what might be expected. So before you go to far into this, maybe just run a quick exp with a magnet to see if anything happens. I would feel bad if I gave you bad advice. Like I said, it what just an idea. Scientist often prove their own hypothosis wrong through experiments. That is why the do them 🙂
      Does that make sense?

      Yah I get it but i already gave the idea to the teacher.

      What happens if nothing happens, well i guess i just say nothing happened 😕 Not a big deal. My dad said to make a magnetic field i need 2 mgnets that one faces the south side and the other one faces the north side.

      So yah i’ll see if anyone else has done this project and has posted their indings on the web.

      Read my post, it’ll give you something to think about if "nothing" happens. Remember nothing is relative to what you’re measuring. If the fish become more active and you were measuring attraction to the magnet then "nothing" happened according to your recording criteria.

      Another thing, remember that magnetic fields decrease with relation to distance(r) with this relationship:

      1/r^2

      Yah i know if nothing happens that’s what i’m measuring so yah i knw that. Also i know that with distance the field decreases in strength
