The seventh graders raised brine shrimp in Mr. Dandridge’s and Ms. Erdelyi classrooms. They looked over them for many weeks and recorded the hatchlings’ actions.
“The first one is always exciting,” says Ms. Erdelyi, a science teacher at Stacey, “It is one you will never forget.” While learning the value of teamwork, effort, and curiosity, seventh graders learned interesting information and facts about these microscopic creatures.
Brine shrimp are commonly found in the Great Salt Lake in Utah; the eggs hatch only in warm conditions. They must have a certain amount of oxygen and salt in the water, and it takes approximately three or more days for them to hatch.
The life cycle of the brine shrimp starts as the eggs hatch. They form large groups together when they are first born. Several months later, they part in their natural habitat and have eggs of their own. Brine shrimp do not have a mating process; both male and female can produce eggs.
Since these shrimp are very difficult to see, one would need more than a school magnifying glass to see them clearly. If you want to see one up close, click on the youtube video.
