=== '''Survival Challenge: Make a Pump Drill''' ===
==== '''Objective''' ====
Students will design and construct a working pump drill using natural and provided materials. This activity teaches engineering principles, problem-solving, and tool-making skills, critical in survival scenarios.
----
=== '''Materials Needed''' ===
==== '''Provided Materials''': ====
* '''Drill Bit''': Metal or salvaged piece (can be substituted with a sharp stone or nail for primitive use).
* '''Cordage''': Strong string, twine, or paracord.
==== '''Natural or Salvaged Materials''': ====
* '''Drill Shaft''': A straight branch or dowel (about 18–24 inches long).
* '''Flywheel''': A heavy, flat piece like a stone with a hole, a wooden disk, or a salvaged object like a metal plate.
* '''Handle''': A crossbar, such as a sturdy stick or dowel (about 12 inches long).
==== '''Tools''': ====
* Knife for carving.
* Awl or drill for creating holes.
* Sandpaper (optional, for smoothing).
==== '''Safety Gear''': ====
Gloves and goggles.
----
=== '''Preparation''' ===
# '''Set Up Workspace''':
#* Create a safe area for carving, drilling, and assembling.
#* Provide safety instructions on tool use and handling sharp objects.
# '''Learning Stations''':
#* '''Engineering Principles''': Explain how the pump drill works using inertia and rotational motion.
#* '''Material Selection''': Teach students how to choose sturdy wood or materials for durability.
#* '''Tool Assembly''': Demonstrate each step of the construction process.
# '''Sample Pump Drill''': Have a completed drill for demonstration.
----
=== '''Challenge Instructions''' ===
==== '''Step 1: Construct the Drill Shaft''' ====
* Find or cut a straight branch or dowel about 18–24 inches long.
* Carve one end to securely hold the drill bit or sharp object.
==== '''Step 2: Create the Flywheel''' ====
# Select a heavy material (e.g., stone, wood disk, or metal plate).
# Drill or carve a hole in the center to fit snugly onto the shaft.
# Slide the flywheel onto the shaft and secure it with glue, wedges, or cordage.
==== '''Step 3: Make the Handle and Cord Mechanism''' ====
# Drill a hole through the shaft near the top, leaving enough space for the handle to move freely.
# Insert the crossbar through the hole to serve as the handle.
# Tie a length of cordage to the top of the shaft, loop it around the crossbar, and tie it back to the shaft below the handle.
==== '''Step 4: Assemble the Drill''' ====
* Attach the drill bit to the bottom of the shaft using glue, a notch, or lashings.
==== '''Step 5: Test the Pump Drill''' ====
# Place the bit against a soft wood surface or material to drill.
# Pump the crossbar up and down to create rotational motion.
# Adjust cord tension or flywheel weight as needed for optimal performance.
----
=== '''Challenge Variations''' ===
# '''Timed Challenge''': Compete to construct a functional pump drill within a set time.
# '''Material Scavenger Hunt''': Include a search for natural or salvaged components.
# '''Advanced Engineering''': Test designs for efficiency by drilling through progressively tougher materials.
# '''Decorative Challenge''': Award points for creativity in the appearance of the finished drill.
----
=== '''Debrief and Reflection''' ===
* Discuss the role of tools like the pump drill in historical and survival contexts.
* Reflect on challenges faced during construction and how they were overcome.
* Encourage students to share insights about teamwork, resourcefulness, and innovation.
----This challenge combines hands-on learning with engineering principles, perfectly aligned with Acton Academy's philosophy of fostering curiosity and self-directed growth.
