 Topic: Science Project?
Posted: November 09 2010 at 2:49pm |
Hi,
My 16 year old was asking about science project ideas. I suggested that doing something with SW chemistry could be both pertinent to current environmental conversations as well and fun and practical. I can even setup a brand new tank etc as part of the project.
I am looking for suggestions of ideas that would work for a science project. Hypothesis and testing to confirm the hypothesis, stuff like that. She's in chemistry right now, so reef chemistry would be a great focus. Just wondering about the implementation and testing of something with maybe 5-6 weeks to put it all together.
One restriction is it can't involve vertibrates.
Ideas?

How about: Reverse Daylight Refugium
People use reverse daylight on their refugium to reduce ph swings when your main tank lights go out.

Well...Maybe not Aquarium related...but, you could do a project on water quality.
The tap water from some cities is better than others. You could take water samples from various locations throughout the valley and test the water...calcium, fluoride, etc.

Last year my daughter did a science project to see which light spectrum grew macro algae the best. She cut two 6 inch lengths of chaeto and put one in a jar under a 6500K bulb and one in a jar under a 10000K bulb. After 6 weeks, she pulled them out and measured them. One grew significantly better.

I asked this question years ago and didn't get much response. I should have tried again because some of these ideas are pretty good. I hate coming up with ideas for science fairs. My daughter a few years ago did experiments on how lighting effects the growth of Phytoplankton.
This year, my daughter is experimenting on how to kill Majano anemones since I basically had to throw away thousands of dollars worth of livestock because they destroyed my tank. All I have left in my tank is live rock and thousands of anemones. I turned the lights and pumps off about 2 months ago and they are still all there.

The effect on pH of water movement and gas exchange, RDP effects, etc.

I wonder if you can control the cal and alk to make it snow in a dramatic effect, as planned, on queue. I'm sure there is stuff to talk about if you can make it obvious enough. I've never seen it happen, in a reef with alk and cal, so I'm not really sure.
A precipitate is sure to be a topic they learn about. I guess it's not super exciting though.
Maybe you could test the amount of cal and alk in coral skeleton. Just to prove where those are going.

That's a fun one that would also provide a show.

Hummm... I have a physical science report due soon, and I was going to do it on keeping a mini reef in your home. We have to stick to "physical science" and not really biology, but I figure if I stay more in gadgits, water flow, balancing chemicals, ph, lighting, temp, etc. I should be cool. Though for a heads up, I may pick on some of you (*looks around at everyone*) and get some interviews on tank keeping. he he he
