Hatching Aquatic Eggs



These are the eggs in their dormant state. They are magnified 200 times. 
Without the microscope, they looked like brown powder!

These are the hatchlings after 4 days (magnified 100 times.)


During science, we are learning about the conditions for life in aquatic biomes. We are doing an experiment to find out how salinity affects the hatching of aquatic eggs. After setting up solutions of various salinities we have observed the tiny eggs to see if they hatch. We discovered that the solution with 2 spoons of salt seemed to be the optimum environment for these creatures.

When we look at them with a magnifying glass, we only see tiny squiggles zig-zagging back and forth. Using a special microscope called a Proscope, we can watch our hatchlings swim and see more detailed features. It has been fascinating to observe them under magnification!

Next, we will learn more about this mystery creature...what type of animal it is and how it lives in its natural habitat.
