The students thought about ways to help minimise climate change and got down to work.
The physical state of water changes as a result of temperature change. With climate change, the ice in the Arctic and Antarctica is melting as the global temperature rises.
Will it melt faster in the Arctic or Antarctica?
Are the consequences of melting ice in the Arctic the same as melting ice in Antarctica?
In class we made our predictions.
We used two ice cubes of the same size.
Then we put a tightly closed jar in a glass. Then we put plasticine on top of the jar to reach the top of the glass. Then fill the glass with water. Finally, place the ice cube on top of the plasticine.
Place the other ice cube in another glass with the same size filled only with water, taking care not to spill it.
Underneath each glass we placed a bowl.
It was easy to see that the ice in the glass only with water melted faster than the ice on top of the plasticine.
So the ice in the Arctic Ocean melts faster than the ice on top of the continent of Antarctica.
We also noticed that the bowl below the glass with only water remained dry. But the bowl underneath the glass with plasticine got wet.
So the ice melting in Antarctica could increase sea level rise more than the ice in the Arctic Ocean.
With this experiment we realised that we have to stop global warming to prevent Portugal and other countries in the world from being flooded.
