Introduction
Imagine you are attending school in Antarctica. The whole school is a big Igloo! Over the last couple of years, slowly the ice around the school has been melting and we don’t know why. The water in the ocean also seems to be getting higher.
If the ice continues to melt or the water keeps rising, what will our school look like in 50 years? Will the school be underwater, on stilts or completely VANISHED? You may need to think about how we will get to school? Will we be rowing or swimming to school?
Task
Today your task is to:
-
Watch this video.
-
Think about what happened to the ice in the glass? Write down what you think occurred and what is the reason is occured? Hint: Think hot and cold.
-
Click the icon to find out more.
Show a page of info about Melting:
Melting is when an object changes from a solid into a liquid.
Items have a melting point, which is the temperature in which it will melt.
The reverse of a melting point is known as the freezing point.
- Now check out this video.
What change in the state of matter can be observed here?
Process
Dig Deeper
Melting and Freezing are processes where our states of matter change.
Rewind: Thinking back to our cold and icy Igloo School, if we know the ice around our Igloo has been melting in recent years, what do you think our school will look like in 50 years?
Will the water become shallower and shrink up? Or will it become rise and become higher and we might need to Swim to school!
Write down a few sentences or create a drawing in your workbook of what you think the Igloo school will look like in 50 years. Will it be on stilts or underwater?
Evaluation
This is how your work will be evaluated.
Conclusion
Congratulations! You have completed this whole Webquest! Remember to share your new knowledge with all your friends. A game you might like to play now is to identify as many different states of matter and where possible, changing states of matter such as freezing and melting as we have explored in this Webquest. Good luck!
