Inuit (Inuktitut) names for ice siku general name for ice saattuqthin ice ainniqcrack in sea ice ipruaqtittuqthick ice maniillatuneven ice created by pressure nanukpolar bear

Frozen Oceans Primary The ice was thick enough to have a camp built on it

Frozen Oceans Primary And even thick enough to land a plane on it

Frozen Oceans Primary Normally the ice was thick enough for the explorers

Frozen Oceans Primary But sometimes, the ice broke up

Frozen Oceans Primary And the explorers had to use their sleds as a raft

Frozen Oceans Primary Or even crawl across very thin ice, hoping it did not crack

Frozen Oceans Primary And if you’re very unlucky, the ice will crack under your bed

Frozen Oceans Primary Sometimes the ice pushes together into ‘ice rubble’

Frozen Oceans Primary Rubble is very hard to ski across

Frozen Oceans Primary The explorers have to choose their way carefully

Frozen Oceans Primary What’s happening to Arctic sea ice? Average What can you tell from the graph? 1.How does the area of sea ice in the Arctic change during the year? 2.Compare the sea ice area between the average and 2012.

Frozen Oceans Primary Why does ice matter?

Frozen Oceans Primary Why does ice matter? Many animals need the sea ice to survive.

Frozen Oceans Primary Why does ice matter? The black water absorbs heat and melts more ice.

Frozen Oceans Primary Why does ice matter? Melting ice can cause sea levels to rise.

Frozen Oceans Primary Why does ice matter? Changes in the ice in the Arctic could make Britain colder.

Frozen Oceans Primary How do you feel about the loss of Arctic sea ice? Do you think people need to work to protect the Arctic?
