Most of the 18 000 fertilized eggs we collected were put into a stream incubator. But, about 2000 eggs were put into an indoor incubator which the students made at the school. The water in the incubator is kept moving all the time. Also, the water is chilled to an average temperature of 4 degrees Celsius. Four degrees is not as cold as in nature, so the eggs will grow more quickly and hatch earlier.
Below are some pictures of us building our incubator. We could not include pictures of the eggs in the incubator because the flash from the camera would hurt the eggs.


Our Class Incubator
We were making our incubator. I was taking pictures of the students with the video camera and a camera. Joewillie and Kevin were licking the connectors. We put on the hoses, tees, valves, clamps, pump, connectors and chiller. The students were very happy and having fun. Mark and Mark R. were laughing very much. Penina and Joewillie were taking some pictures too. It was a lot of fun in our class. We made the incubator in about two hours.
