Older students might develop another MatchCard for two additional classes of fires:

Fire Extinguishers

Every home should have a fire extinguisher. If you do not, or you check the date and it is expired, now’s a great time to purchase a fire extinguisher. Let your student(s) help you pick it out. Look at the numerical rating on the extinguishers. Compare costs.

And of course, there is no sense having an extinguisher if you can’t use it. If you found your old one is expired, use it for practice. If you don’t have an expired extinguisher, use an inexpensive new one to conduct an annual practice session.

Practicing Using the Extinguisher

The mnemonic P A S S reminds us how to use a fire extinguisher: Discuss what would happen if you didn’t follow this order.

Fire and Oxygen

Smother A Fire

Fires need oxygen to burn. To demonstrate this, light a candle. Then put a transparent glass bowl or glass over the top. Watch the flame be extinguished.

Build A Campfire

If your child has not had the opportunity to start a fire (a common scouting activity), look for the chance to give him or her the chance to do so. It takes a little know how and practice. Start with small dry grass or twigs, add larger twigs, then sticks, small logs and large logs. Have them start by making piles of the five sizes of wood.

Fire Safety

More information on teaching fire safety can be found on our worksheet and activities for home safety. MatchCard 7 describes some of the most common safety hazards in homes, including fire.

Let's Think About It: Oxygen

Oxygen is highly flammable. You will see people in the community with chronic lung diseases carrying portable oxygen and inhaling it through tubing. These individuals could not go to a camp, or even sit at a restaurant with a burning candle. What other life changes would this require?

How To Use MatchCards


MatchCards make science concepts and corresponding vocabulary interactive. As students move the information pieces on the MatchCards they review the material they have already learned.
