Fulfills Steps 3, 4 and 5 of GSUSA Brownie Automotive Manufacturing badge requirements.
This is designed with the goal of producing around 50 automotive-themed SWAPs per scout. Scale up or down per your troops needs for upcoming events that use SWAPs.
Items Needed (per assembly line):
- Supplies to make a simple automotive-themed SWAP (see sample suggestion below)
- A completed example SWAP
- Paper and pencils for team planning
- Timer
- Pins or safety pins to attach SWAPs
- Labeled bins or trays to organize SWAP parts
- Extra table space for sorting and building
Prepare Before the Meeting:
- Choose one SWAP design with multiple simple steps that can be done by hand (see below for a sample idea and images of other auto-themed SWAPs).
- Pre-cut or prep any materials that require adult help (like cutting straws, glue-dot portions, or punching holes).
- Create a completed example SWAP for scouts to reference.
- Determine how many stations (assembly steps) the SWAP will require and ensure enough parts are available to produce 50 SWAPs per scout.
Instructions (Estimated Time: 45-50 minutes):
- Introduce the Challenge (5 minutes)
- Show the completed SWAP and explain that each team will create an assembly line to produce as many SWAPs as possible, aiming for 50 per scout.
- Briefly review the idea of assembly lines and why manufacturers use them: speed, organization, and teamwork.
- Plan the Process (8 minutes)
- Divide scouts into 2 or more teams depending on troop size.
- Each team studies the SWAP design and lists out the steps needed to build it.
- Scouts assign themselves jobs so each person has a specific task (e.g., attach wheels, glue body, add pin).
- Teams draw a quick plan for their assembly line and organize their materials by step.
- Round One – Build & Time (12 minutes)
- Set a timer for 10 minutes.
- Teams build as many SWAPs as they can using their assembly line plans.
- Scouts should pause for quick quality checks every few SWAPs.
- Reflection & Revise (5 minutes)
- Stop the timer and count completed SWAPs.
- Each team discusses what worked, what slowed them down, and how they could improve their process.
- Teams adjust jobs or layout as needed.
- Final Round – Build Again (15 minutes)
- Start the timer again. Scouts return to their lines and build more SWAPs using their improved process.
- Continue until time runs out or supplies run low.
- Wrap-Up & Share (5 minutes)
- Each team shows off a few finished SWAPs.
- Scouts reflect on how teamwork, job roles, and planning helped them meet their goal. What would they do differently next time?
Suggested Automotive-Themed SWAP:
Try a Paper Car SWAP. It uses paper cards (the size of a business card) with a car printed and a cute phrase. Supplies are the cards, two buttons each card, a safety pin per card, and glue to attach buttons.
Assembly line steps could be:
- Add buttons for wheels
- Attach pin
- Check quality

Ideas for cute phrases:
- “Wheely glad to SWAP with you!”
- “Button up and roll out!”
- “Driven to make new friends!”
- “Rolling by to say hi!”
- “Fueled by friendship and fun!”
- “Honk if you love Girl Scouts!”
