Science Week at Clooncagh

This week at Clooncagh we had great fun celebrating Science Week! We learned a lot about convection currents in particular. Convection currents have a lot to do with the way heat rises and cold sinks. In the oceans the hot water rises to the top and the cold water sinks. The salt water also affects this, the water in the oceans is salty but when the water from the ice caps melt the salt water sinks to the bottom and the fresh water comes to the top. These currents are called thermohaline currents. In a science experiment in Mr. Dukes classroom he filled a large container with water and put it on top of the cooker. He put a dyed ice cube in the water and it melted like normal and sank to the bottom. Then he turned on the heat and the water heated up so that all the dyed water rose.

We also watched a video to make sure we understood what was happening, the video was really good as it made us understand what was happening but was still really fun to watch, The name of the person in the video was Bill Nye the Science Guy. Our teacher took photos of the experiment too.
