4th Grade

What I learned today:

 

First Visit –
  • Today we learned about smoke and that it is poisonous, hot and impossible to breath.
  • We learned that we cannot smell or see smoke in our sleep.
  • We learned that a smoke detector gives us early warning of smoke in our home.
  • We should find smoke detectors on the ceiling in bedrooms and on every level of our house.
  • The best kind of smoke detector is a working one.  However many smoke detectors in homes do not work.
  • We learned that a smoke detector has three parts a sensor (sniffer), a speaker (horn sounder) and a power supply (battery).
  • We learned how to use the test button to make sure our smoke detector works.  We do this every month.
  • We replace the battery every six months.
  • We get a new smoke detector every ten years.
  • Our homework is to see how many smoke detectors we have a home and if they work.

Second Visit –
  • We reviewed our homework and talked about who had non-working smoke detectors and how they fixed them.
  • Today we learned about geometry.  Really?
  • We learned about the FIRE TRIANGLE.  The fire triangle is made up of three sides, fuel, heat and oxygen.
  • We learned that if we can remove one leg of the triangle, the fire will go out.
  • Fuels in solids, liquids and gases.
  • A solid fuel might be wood.  A liquid fuel might be cooking oil and a gaseous fuel would be natural gas.
  • Heat is required for fuels to reach their ignition temperature.  Heat sources include sparks, electrical energy, friction and many others.
  • Oxygen is all around us and we cannot control oxygen levels.
  • We learned that we all have a new job- to prevent fires by keeping the three parts of the fire triangle from coming together.
  • When we see the three parts of the triangle coming together, we call this a FIRE HAZARD.
  • We then looked at several examples of fire hazards and discussed how to correct them.
  • Our homework is to look at rooms in our home watching for fire hazards.  We will correct them and tell the class how we did it next time.

Third Visit –
  • Today, the fire department brought the fire safety house.
  • The fire safety house is really a trailer, but just like a real house it has a meeting place in case there is a fire.
  • We picked the flag pole for our meeting place because it is ALWAYS THERE, AT LEAST TWENTY FEET AWAY, IN THE FRONT OF THE HOUSE, and ON THE SAME SIDE OF THE STREET.
  • Inside the fire safety house we reviewed some points from earlier lessons.
  • Then, the smoke detector went off!
  • We learned to crawl to the door (our primary escape route), and open it a crack to check the hallway.
  • The hallway was blocked by smoke!
  • We then shut the door, used a blanket to keep smoke out of our room and crawl to the window (our secondary escape route).
  • We then climbed down the fire safety ladder and went to our meeting place.
  • At the meeting place we remembered our two jobs: to count noses and call 9-1-1.
  • After the “fire” was out and it was safe to go back inside we went in with the firefighters to investigate what happened.
  • We found that the fire triangle had come together.  An electrical cord (the heat source) had shorted out under a rug (the fuel source) and mixed with the oxygen in the air to create a fire.
  • Fortunately the smoke detector gave us early warning so we could escape.
  • We reviewed that we should check our smoke detector once a month, we should change the battery every six months and we should replace smoke detectors every ten years.
