Winter Outdoor Survival Skills

My boys are both in Cub Scouts, and are preparing for our district's annual Winter Fun Day, where the scouts their age complete a winter survival skills challenge. These 4th & 5th graders will go on a hike (backpacks required) and will have to build an outdoor shelter using the items they have with them. They will also have to build a campfire safely and properly. They will be quizzed on the items they have in their backpacks and what each item is for.

Today, while I gave them a short break from their schoolwork, this is what they constructed entirely on their own.

I think they're ready for Saturday's challenge!
