Stand the spaghetti upright and stick the other end into the clay on the card. Release the spaghetti. Repeat steps 3 and 4 using shorter pieces of spaghetti until you find the length that the clay will support. Inupiat are the native people of Alaska's North Slope, which includes the town of Barrow, the northernmost community in the United States. Children born in the Arctic regions of Alaska , be they Inupiat or another race, never see a real tree unless they travel out of the Arctic tundra .
Tundras are dry with long, cold winters and short, usually cool, summers.
The tundra's lack of moisture, cold temperatures, and short growing season are factors that prohibit tree growth. In the Arctic tundra, permafrost thaws to a depth of only 18 in. Tree roots cannot grow in such a shallow space. And even if they could, they would die when the ground refreezes during the long, cold winter. In the activity you saw that the clay could support a piece of spaghetti only about 2 in.
