Yesterday, we had our first eggs hatch!  The newly hatched eggs are called alevins.  They look like this:

The sac on the bottom of the newborn baby trout is its egg, which it is still using for nutrition.

Middle school students viewed one of the alevins under our new digital microscope, which is able to take pictures and videos.  Below, see a closeup picture, taken by 8th grader Hunter, of the alevin's spine and another of its egg sac:

It's so exciting to have new life in our classroom!  Feel free to come down and see the new babies.
