Biology Homework Help me?

Bio HW BCR

The concentration of salt in water affects the hatching of brine shrimp eggs. A scientist want to determine the best conditions in which to hatch the shrimp eggs. In a laboratory, brine shrimp will grow at room temperature in small glass containers of salt water.
-Describe the steps of a controlled experiment that would determine the best saltwater concentration in which to hatch brine shrimp eggs.

In your response, be sure to indicate
-the materials that would be used
-the type of data that will be collected
-how the data will be used to answer questions about the salt requirements of brine shrimp

PLEASE HELP.
Just…help me start off?
I’m not sure how to start this and where to go with it…

Its all greek to me.

Brine shrimp and ammonia?

We have to do an experiment in my biology class to determine the effect a variable on the hatching of brine shrimp; we can choose any variable we want. My group is going to test the effect of nutrients (mainly nitrogen), and at first we thought we would using plant fertilizer (without any poisons of course). Now I’m considering using ammonia, and I’m wondering if that would be a bad idea because I have to bring it to school. I don’t care about the effect it will have on the eggs because, well, it’s an experiment, and the whole point is to see what happens. It’s not dangerous is it (unless you drink it or something of course)? The odor is pretty localized and won’t spread through the whole room, right?
Well, I don’t care if they die as long as they hatch. :P And the salinity was an obvious variable that a lot of people are doing, so we didn’t want to do that. I also think light would be harder to control. Thanks for the replies!

What is important to include/look-up in a scientific lab introduction? BIOLOGY LAB…

I’m doing a lab on juvenile brine shrimp. First they are just put into four sections with no factors changed (like a control) and then counted after 30 minutes. Then the same thing happens and they are broken up into four but each one is exposed to a different amount of light. It is to compare aboitic and biotic factors or independent and dependant factors that affect them.

What should I look up and research for the introduction?
What should I include and in what form/ order (ie; background info, hypothesis; justification for hypothesis?)

a couple of biology questions please help me???!?!?!?

Brine Shrimp (newly hatched)

Newly hatched brine shrimp (SeaMonkeys!) under a dissection microscope. Much better than those peasly little plastic magnifying bits on the tank.
