Brine Shrimp
Since last time we experimented with brine shrimp we got some weird results so we decided to try a new experiment. We put brine shrimp in test tubes full of sugar water, sprite, clean water, salt water and lemon water and put the vials under a heat lamp. Brine shrimp can hatch in many different liquids but only in a few they can live we found out. The brine shrimp hatched in all the liquids but only lived over the whole period of time in salt water and sugar water. We were all so happy that they hatched in the salt water because we have been trying to do this for a while now. Our evidence is we put the little eggs under the microscope and looked to find life such as empty eggs and the shrimp swimming or just staying in one spot but out of the egg. We found is the second day in every liquid but the third day we only found them still swimming in two. Some of the error we had is that we could not get the exact same amount if eggs in each, we also could not get the exact same amount of liquid in each vial. I observed some if the live brine shrimp moving and swimming around. I got to see a few of the shrimp come out of the eggs. That helps me to know that there was living brine shrimp. I understand now that the shrimp need their own environment to live in. When we did the experiment with the brine shrimp and did not put it under the heat lamp we dud nit get any to hatch in anything but sugar water but once we put it under the lamp more hatched. I still don't understand why the eggs could hatch in different environments and how they only sometimes hatch in salt water. I think it's odd how they don't hatch in their natural environment.
