Survivor Alevin

Today we explored the obstacles that Alevin have to overcome to survive once they hatch.  We used creative movement and tag to simulate the hazards and predators that the Alevin face.  Now we understand how lucky they are to survive!

Swim Bladder Investigation

Yesterday we used some film canisters and plasticine to investigate how salmon can stay afloat in the water.  It was challenging trying to get them to float under the water but not touching the bottom!

Dilution

Everyday we test the water in the salmon tank to see how much ammonia is in there.  When there is too much we replace half the water to dilute and amount of ammonia.  

Today we used green food colouring, water and pipettes to help us understand what diluting a solution means.

Long shadows

To begin our learning on space we went outside to measure our shadows at different times of the day. The first ones on the right were traced around 9:30 and the second ones on the left at 11:45. The shadows are long because it is winter and the sun is low in the sky.
