On the Monday the whole school was excited to learn that the little salmon had started to hatch. By plugging the microscope into the laptop we were able to project the images straight onto the white board.
One of the eggs hatched in front of the class and the little alevin wiggled out. The big egg sac meant that he had to really move a lot to make any headway. Whilst we will have a few weeks to be taught how to swim next term. The salmon know how to swim straight away without anyone there to teach them. It is all pretty amazing.
The children all had a go at taking some of the photos. If you take them in quick succession you can stitch them together to make a little animated 'GIFF' that makes it look like it is moving.
You can see a lot with a magnifying glass but the microscope -cheap as it is- really does open up a whole new world for the children to explore. The Alevin is only about 2cm long, its only about 2mm wide apart from its egg sac which is about 8-10mm.
Again you can see the blood vessels and because it's a moving photo you can see that it is 'breathing the water' in and out as the gills open. You can again make out the heart pumping and the speckled pattern on his skin to help camoflauge him.
We think we can see a lens forming on the dark saucer shaped eyes, what do you think?
