Your assignment
Mission briefing
The ranger station has misplaced three clues to how fire works. Your detective team must find heat, fuel, and oxygen, then explain why removing one breaks the triangle. This investigation never uses a real fire.
Learning objectives
- • Name heat, fuel, and oxygen as the three needs of fire
- • Distinguish fuel from nonfuel examples
- • Explain why removing one part prevents the triangle from working
Parent preparation
- • Draw a large triangle and prepare picture cards before the child arrives. Keep matches, lighters, candles, batteries, and ignition tools out of the activity area.
- • If using wood samples, inspect for splinters and mold; use pictures instead for children who mouth objects. Choose a shaded spot so a magnifier cannot focus sunlight.
Mission steps
- 1
Open the case
Read the three labels aloud. Explain that a fire needs all three together; the triangle is a model, not an experiment with flame.
- 2
Sort the evidence
Offer one picture at a time. Place wood under fuel, the pictured lighter under heat, and the air card under oxygen. Set water aside as a nonfuel example.
- 3
Build the triangle
Have the child place each label at a corner and name it. Explain that ordinary air supplies oxygen, but air alone cannot make fire.
- 4
Remove a clue
Take away the heat card. Ask whether this model has all three needs. Repeat with fuel and oxygen without performing a real-world demonstration.
- 5
Close the case
Let the child explain the triangle back to you and draw the three clues. Put all samples away together.
Choose your challenge
Suggested levels, not eligibility guarantees. Adults assess readiness and conditions; all safety boundaries apply at every level.
- DiscovererTypically ages 5–7
- Adult reads labels; child matches three pictures with help.
- ExplorerTypically ages 8–11
- Child sorts six pictures and explains one missing corner.
- Trail LeaderTypically ages 12+
- Child builds a new picture puzzle for the adult and explains each correct match.
Completion requirements
- Match all three triangle labels with adult support as needed.
- Explain one missing-part example using pictures, not a flame.
Reflect together
- Which clue stands for fuel?
- What changes when one corner is missing?
- Why did our detective work use pictures instead of fire?
Setting
- • Indoor table or dry, sheltered backyard table
Required supplies
- Paper triangle and three paper labels
- Pencil or crayons
- Adult-selected pictures of wood, water, sunlight, a lighter, and air
Optional supplies
- • Three large clean wood samples
- • Magnifying glass for looking only
Safety notes
- No ignition, hot surfaces, or flame demonstrations; discuss pictured heat sources only.
- Air contains oxygen; children must not test breathing restrictions or cover anyone’s face.
- An adult handles any rough sample; do not collect or taste unknown plants.
Stop conditions
- Stop if a child brings an ignition tool or tries to create heat. Remove it before resuming.
- Switch to pictures if splinters, irritation, or mouthing occurs.
