Seventh graders in Mr. Dandridge’s class are about to begin the brine shrimp experiment! In this experiment, brine shrimp will be living in various conditions. Brine shrimp need specific conditions to hatch, so observing which condition is the best/fastest for the shrimp are experiment-worthy.

In an interview with Mr. Dandridge, a Stacey Middle School science teacher, he stated, “This experiment will teach students setting design, variables in experiments, and an understanding of affect outcome.”

When asked what his favorite part of doing this experiment every year, Mr. Dandridge said, “My favorite part about doing this every year is seeing the students’ reactions and their strong desire to want to come to school every day to keep themselves updated on the shrimp.”

Brine shrimp, commonly known as sea-monkeys (mainly for the structure of their tail), are aquatic crustaceans in the class Artemia. They are now the only species left in class Artemia. They have been around since the Triassic Period, which was about 199 million years ago; even then, Artemia had very few species in its class.

Brine shrimp eggs are as small as grains of sand and hatch once they are in the right environment; dormant eggs are called cysts. Once hatched, the shrimp can grow to be as long as one centimeter (approximately 0.4 inches). Although these aquatic creatures are awfully small, they are the largest organism that thrives in the varying water temperatures of the Great Salt Lake located in Utah and is a major factor in its ecosystem.

The brine shrimp will be observed for about a week. Certain parts of this assignment will be graded, as Mr. Dandridge says, “I need to know what important facts you’ve learned about brine shrimp from this experiment . . . .” If you’re in Mr. Dandridge’s science class, get excited about this experiment!


    • IKR, I did this last year in Mr. Dandridge’s class, + it was so fun + intriguing.


  1. Remember, if you want to give these little guys a good home, just ask your science teacher at the end of the experiment and he/she will be happy to let you take some home.
