All Hatched!

Hatching is done.  Here's a quick video of a group of the hatchlings.

Hatching!

The first eggs are starting to hatch.  At this point they do not resemble fish, they appear to be an egg with two eyes and a little white tail.  Here is a quick video of the female on the eggs that have not yet hatched.

Spawning in the Science Room

When I came into school yesterday I got quite the surprise. Overnight, one of my brown bullheads made a nest and laid a mass of eggs. At this point I wasn't sure if one of the other two brown bullheads in the tank was a male to fertilize them, but as the day progressed it seemed that one was displaying nest protecting behavior typical of a male. So the current hypothesis is that we have a true spawning event and that we can expect hatching within the next 6-9 days. 

Spring Migrants

The spring migrants are starting to show up in decent numbers.  The marshes are filling up with male Red-winged blackbirds presenting you the with opportunity to see interesting territorial displays as they compete for their habitat.  The females will be arriving soon and will breed with the males who have set up the best territories. 

Attention Chemistry Students

All Molar Heat Capacity Lab trials need to be completed by Tuesday 2/7/12 at 3:30pm.  Trials can be done before school, after school, or during study halls (by appointment only).

Open House

Stop in at our Open House on February 15th from 5:00pm - 7:00pm.  The science department will be demonstrating a Cellular Respiration + Photosynthesis Lab using Vernier data acquisition probes and the Promethean Board.
