Helium, 2, Department of Education, School Operations - Kivalliq Baker Lake, NU
Helium: Helium was originally discovered on the sun. The element gets its name from the Greek word Helios which literally means "the sun". The sun was chosen in my design because it is unique to this element, and it fits well with my design. I chose to place an Inukshuk in my design because it is a symbol that represents Inuit culture. The Inukshuk was placed at the top of the world to represent its place in the territory of Nunavut. Inukshuks are used to guide hunters and provide direction which has been important to the survival of our people.
