2. Repeat with steel wool. Try ... ... a tightly rolled "snake" ... .. a thin, wispy "cloud" ...


3. How should you prepare iron to make it burn? Does your answer apply to wood? Explain.

4. Write a number in each box to balance this chemical equation:

* Use eye protection.

* Don't touch hot metal--let it cool.

* Use paper or foil to protect tabletop.

* Keep clothing and hair away from flame.


To study the rapid oxidation of iron to iron oxide. To understand that smaller particle size speeds the burning process.


Copy the lab for each student or lab team.

Steps 1-2. Common sense dictates careful supervision when using fire or any potential hazard. Caution students that iron can burn skin severely even if it appears cool. A paper mat serves both to protect table tops and give visual evidence of burn hazards (smoke and burned holes). Or, use foil to reduce smokein the air. Step 2.
