We recently attended a wilderness survival skills workshop at the Anita C. Leight Estuary Center. The focus was to learn a few skills and create a mini survival kit: a baby food jar with emergency supplies.
The instructor began by telling us what we needed to do if we found ourselves lost in the woods, and asked us to think of all the items that could be useful to us in order to survive.
She provided us with foil and we talked about how it could help us survive. We tried to make a cup which could hold water:

The cups held water for a few moments--long enough to get a quick sip:
We discussed various emergency supplies which would be needed to survive temporarily in the woods, then gathered around a table and in assembly-line fashion filled our jars with duct tape, safety pins, string, foil, band-aid, cotton ball, and a few other essentials:

The completed mini survival kits:
Our instructor explained that other items could be useful, too, such as matches, painkiller tablets or aspirin, or a plastic trash bag folded up very small, and that we could customize our kit at home.
Next, we explored the woods outside the nature center to find suitable places to create a temporary shelter. Groups of trees and places with dense shrubs or vines are good because a plastic bag can be tied to the trunks or draped on the bushes to serve as shelter and protection from wind and rain:

Since the workshop, Jacob has immersed himself into learning more about wilderness survival. He constructed survival bags with shoulder straps out of duct tape:

He made a picture list of the items he thought he should put in his bags:
Some items still need to be purchased (like a very small compass and a
small thermal blanket) but for the most part, they're ready to be taken
on an adventure and to practice our skills.
He wants to learn how to start a fire with flint or a bow drill, construct a temporary shelter in the woods, and make some animal traps. There's so much to learn about wilderness survival!
Here are some sites we've explored about wilderness survival: Tom Brown Tracker School, Wildwood Survival, and A Kid's Wilderness Survival Primer. Some of the books we're reading can be seen in "Jacob's Reading" on the right-hand sidebar.
We're also going to take a closer look at Night Owl's Creations' Wilderness Survival Unit Study.
