flat = Brine shrimp hatching  =

Monday the fifth grade class put shrimp eggs in water and added 0 teaspoons of salt, 2 teaspoons of salt, 4 teaspoons of salt, 6 teaspoons of salt. On Tuesday they looked at the cups. There was no shrimp in the 0 teaspoons, there were about 10 shrimp in the 2 teaspoons, there might have been some in the 4 and 6 teaspoons. The shrimp were almost clear when they first hatched and then they turned pink and almost red. They have no eyes so they just swim out of control. By: Derek Baker
