=== '''Survival Challenge: Make a Handsaw''' ===

==== '''Objective''' ====
Students will use a provided saw blade and natural or salvaged materials to craft a functional handsaw. This challenge develops problem-solving, creativity, and practical craftsmanship skills essential for survival scenarios.
----

=== '''Materials Needed''' ===

==== '''Provided''': ====

* Saw blade (toothless strip or salvaged blade with teeth intact).
* Metal wire or strong cordage (optional, for securing blade).

==== '''Natural or Salvaged Materials''': ====

* '''Handle Material''': Sturdy branches or wood pieces (hardwoods like oak, ash, or maple work well).
* '''Fasteners''': Natural cordage, vines, or salvage items like nails or screws (if allowed).
* '''Tools''':
** Hatchet or handsaw (for shaping wood).
** Whittling knife.
** Drill (manual or improvised awl).

==== '''Safety Gear''': ====
Gloves, goggles, and a first aid kit.
----

=== '''Preparation''' ===

# '''Set Up Workspace''':
#* Prepare a safe crafting zone with cutting and assembly stations.
#* Provide demonstrations of tool use and safe handling of sharp objects.
# '''Teach Basic Principles''':
#* Explain how saws function and the importance of stability and ergonomics in handle design.
#* Show examples of basic saw designs (e.g., bow saw, straight-handled saw).

----

=== '''Challenge Instructions''' ===

==== '''Step 1: Design the Handsaw''' ====

# Decide on a saw type (e.g., straight handle or bow saw).
# Sketch or plan the design before starting.

==== '''Step 2: Craft the Handle''' ====

# '''Straight Handle (Simple)''':
#* Select a straight, thick branch (about 1.5–2 inches in diameter).
#* Carve a groove to seat the saw blade securely.
# '''Bow Saw Handle (Advanced)''':
#* Find a branch with a natural curve or assemble a bow shape from multiple pieces.
#* Use cordage to create tension across the bow to hold the blade.

==== '''Step 3: Attach the Saw Blade''' ====

* Drill or carve holes in the handle to align with holes in the blade (if present).
* Secure the blade using cordage, natural fiber, or metal wire.
* If no pre-drilled holes exist, carve notches to seat the blade tightly and lash it in place.

==== '''Step 4: Test and Refine''' ====

* Use the saw to cut small branches or wood.
* Adjust the handle or blade attachment for stability and comfort.

----

=== '''Challenge Variations''' ===

# '''Timed Build''': See who can create a functional saw the fastest.
# '''Material Scavenger Hunt''': Incorporate a scavenger hunt to find natural materials for the handle.
# '''Durability Test''': Test saws on progressively thicker wood to assess strength and effectiveness.
# '''Design Creativity''': Award points for ergonomic design or innovative attachment methods.

=== '''Debrief and Reflection''' ===

* Discuss what worked well and what could be improved.
* Reflect on how designing and building a tool enhances problem-solving and adaptability.
* Share insights into teamwork and resourcefulness during the challenge.

----This challenge is ideal for fostering ingenuity and engineering skills while emphasizing the importance of functional tools in survival situations. It aligns with Acton Academy's learner-driven approach and encourages practical application of knowledge.
