Mineral Spark & Rock Friction Science Lab

30 mins Ages 7-9 Outdoor

An engaging, screen-free learning activity that builds real-world creativity and critical thinking for kids aged 7 to 9.

Materials Needed

  • • Ferrocerium fire steel rod with scraper (1 unit)
  • • Metal pie pan or baking sheet (1 unit)
  • • 100% pure cotton balls (3 units)
  • • Water quenching cup (1 unit)

Pro Tips

  • → Pull the ferrocerium rod backward against the stationary striker rather than pushing forward; this prevents knocking over your tinder.
  • → Fluff out a cotton ball into a wispy nest; dense cotton will not catch sparks easily.
  • → Keep a cup of water beside the metal pan for immediate quenching after ignition.

Safety First

Conduct strictly over a metal pan on concrete or dirt away from dry brush. Adult supervision required.

Step-by-Step Instructions

1

Step 1

Set a clean metal pie pan flat on a patch of bare dirt or concrete, away from dry brush.

2

Step 2

Fluff out a single dry cotton ball into a loose, airy fiber nest in the center of the metal pan.

3

Step 3

Position the tip of the ferrocerium rod directly against the edge of the cotton nest at a 45-degree angle.

4

Step 4

Scrape the steel striker firmly down the rod to shave burning sparks onto the tinder until it catches, then extinguish safely.
