Survival Challenge: Make a Net

Objective

Students will design and create a functional net using natural fibers or provided cordage. This challenge teaches practical survival skills, teamwork, and resourcefulness, while introducing knot-tying techniques and the basics of weaving.

Materials Needed

Provided Materials:

• Cordage: Twine, paracord, jute rope, or plant fibers (for advanced learners).
• Frame (optional): Branches or sticks to create a loom-like structure.

Natural or Salvaged Materials:

• Long grass, cattail leaves, bark strips (e.g., willow or cedar), or vines.

Tools:

• Knife or scissors for cutting fibers.
• Awl or stick for making holes (optional).

Safety Gear:

Gloves (for handling rough fibers) and a first aid kit.

Preparation

1. Workspace Setup:
   • Choose a safe outdoor or indoor workspace with enough room for students to spread out.
   • Provide a demonstration area for teaching knots and weaving techniques.
2. Teaching Stations:
   • Knot-Tying Basics: Demonstrate square knots, slip knots, and overhand knots.
   • Net Patterns: Show examples of different net patterns (e.g., square mesh or diamond mesh).
   • Material Prep: Teach how to harvest and prepare natural fibers if applicable.
3. Sample Net: Have a finished net ready for inspiration and to show the final goal.

Instructions

Step 1: Design the Net

• Decide on the net's purpose (e.g., fishing, carrying items, or trapping).
• Sketch the size and pattern of the net.

Step 2: Prepare Materials

1. If Using Natural Fibers:
   • Collect fibers and soak them in water if necessary to increase flexibility.
   • Strip fibers into long, thin pieces and twist them into cordage if not using pre-made string.
2. If Using Provided Cordage:
   • Cut cordage into appropriate lengths based on the net size.

Step 3: Construct the Frame (Optional)

• Create a rectangular or circular frame using sturdy branches or sticks.
• Secure the frame with lashings or by planting it into the ground.

Step 4: Weave the Net

1. Tie a horizontal top cord to act as the main line.
2. Cut multiple vertical cords (for warp lines) and attach them evenly to the top cord.
3. Tie knots at equal intervals to form a grid pattern (square or diamond).
4. Continue adding rows of knots, ensuring the spacing is consistent.
5. Finish by tying the bottom row securely.

Step 5: Test the Net

• Use the net for a survival task such as catching lightweight objects, trapping small items, or carrying materials.

Challenge Variations

1. Timed Build: See who can create the most functional net in a set time.
2. Material Scavenger Hunt: Add a scavenging element for natural fibers.
3. Strength Test: Test nets for durability by lifting progressively heavier objects.
4. Advanced Patterns: Introduce more complex netting techniques, like triangular or hexagonal patterns.

Debrief and Reflection

• Discuss the historical and practical uses of nets in survival scenarios.
• Reflect on what worked well during the challenge and what could be improved.
• Share insights on the importance of precision, teamwork, and creativity.
