Snow Shelter

We're Morgan, Thianna, and Rio, and we dig SNOW! Not only do we dig it, we jump in it, ski on it, and snowboard over it. But snow isn't all fun and games. Getting stranded in snow and freezing cold weather can be really dangerous. We built a snow shelter called a quinzhee. It's actually a little cave you dig in a big mound of snow. But we weren't sure it would really keep us warm overnight. For our segment on DragonflyTV we asked: Will a snow shelter keep you warm when the temperature dips below freezing?

How would you investigate this question?
What equipment would you need? How would you keep track of the temperature both inside and outside the snow shelter? Write your ideas in your notebook then discuss them with your class or visit Snow Shelter to see what the DFTV scientists found out.
