Hypothesis
If acid rain does affect zooplankton then many zooplankton will die, their life span will get shorter and they will not produce as many offspring.
Materials
- Two 400 mL tanks filled with 350 mL of marine algae medium water (after 3 weeks I will add 15 more mL to each tank
- Rotifers (keratella) * measure container size
- Platymonas (their food) * measure container size
- Microscope (to count the rotifers)
- Sulfuric acid diluted to a ph of 4
- Pipette (to put a certain amount of acid rain into the acid rain tank)
Variables
To grow my rotifer, I am putting them in a tank for a certain amount of time (probably 1-3 weeks) with 900 mL of medium marine water (the water that I supplied in the tank, platymonas, (what I will be feeding them). Then, just for the acid rain tank, I will put in acid rain. I don’t think I have to feed them more than once because after the first time I put the platymonas into the tank, I do not have to do it again because the algae produces more of itself, by itself.
Ms. Minn will be the one producing the acid rain. The acid rain she makes consists of sulfur dioxide and carbon monoxide and a ph of around 2.
Procedure
The procedure that I will do will go along the lines of this:
1. Fill two tanks, to start, with medium marine water, a mimic of the water that they live in, in their natural habitat, with the pH of around 7.
2. They will both be filled with rotifer or around the same count of them (if that is possible).
3. Then, I will add a certain amount of “acid rain” into it. I will put the acid rain into one of the tanks every one to two days. I will do this consistently for a certain amount of time until the entire colony of rotifer die, if it affects them in that way while they are in the acid rain tank.
Prediction
My prediction is that the colony of rotifer, without the acid rain, will produce very well, and at the end of my project, will have many more rotifer in it than the other one. But on the other hand, the acid rain tank will not produce well at all. I think their food will die, so they will have no food supply. If they have no food supply, they will not be able to survive. So I am saying that they will not be very successful, and fail to live for more than 3 weeks.

I looked at my rotifer again but I haven't seen anything moving so I'll give them two more days to grow

My Rotifer!
All of my Rotifers died. We are getting new ones tomorrow. I will do a better job in taking notes and pictures.

getting data.
Every day, before I put the acid in the acid tank, I will take samples of how many rotifer there are per mL. Then, I will multiply it by 550. I will do this to both tanks.
I haven't done this yet because we had a double snow day, leading into a six day weekend, therefore, I did not take samples today. I will take them everyday for now and on.
