How a ‘Fire‑Making’ Project Ignites STEM Learning: A Case Study

Abstract

STEM education centers on science and engineering problems, offering students interconnected learning experiences. Using the research‑based project “Drilling Wood to Make Fire” as an example, the paper describes curriculum development, learning‑goal definition, teaching practice, and reflection, highlighting the project’s process, difficulties, and breakthroughs that cultivate innovative talent.

Keywords: STEM, project‑based learning, drilling wood to make fire

1. Case Background Analysis

1.1 Development Rationale

The author, a consultant for CCTV’s science channel, was invited to plan a program on the history of oxygen discovery, which required a video of modern students replicating ancient fire‑making. The task was assigned to a high‑school technology club.

1.2 Learner Analysis

Participants were high‑school sophomores with solid physics and chemistry foundations, strong hands‑on skills, and a scientific background, making them well‑suited for the “Drilling Wood to Make Fire” challenge.

2. Theme Course Design

2.1 Teaching‑Goal Analysis

Scientific goals focus on high‑school physics (mechanics) and chemistry (combustion) concepts: force analysis, energy transformation, and combustion conditions. Technological goals involve information search, tool design, and engineering problem solving, while mathematics provides quantitative analysis of tool parameters and energy calculations.

2.2 Design Idea

The STEM course adopts a project‑based learning model where students work in groups to solve the fire‑making task, integrating engineering, scientific inquiry, and mathematical computation.

3. Detailed Teaching Process

3.1 Phase 1 – Principle and Combustion Analysis

Students watch a survival video, discuss fire‑making principles, and identify three essential combustion conditions: fuel, oxygen, and sufficient friction heat.

3.2 Phase 2 – Tool Development

After one week of research and force analysis, students design wooden tools, add an air inlet for oxygen, and fabricate auxiliary devices using the school’s technology lab, applying physics, chemistry, and mathematics.

3.3 Phase 3 – Experiment and Improvement

Initial hand‑drilling attempts fail; students collaborate, redesign a gyroscope‑type drill using a 3D laser cutter, and conduct repeated experiments. Despite smoke generation, fire is not achieved due to limited airflow and low ambient temperature.

4. Teaching Reflection

The project emphasized experiential STEM learning, demonstrating the importance of experimentation in science. Students gained deeper appreciation for scientific rigor, collaborative problem‑solving, and engineering thinking, confirming that project‑based STEM education effectively cultivates innovative capabilities.
