KOG Ranger Program
How Things Burn
What is the fire triangle? Young ranger learn about the three elements needed to start a fire and keep it going (heat sources, fuel sources, and oxygen) with a class demonstration involving a candle in a jar.
Curated OER
Rusting, Burning and Oxygen
In this rusting, burning and oxygen activity, students read about chemical reactions and are given diagrams of a rusting bicycle, a burning candle, and a variety of chemical changes. Students make observations and explain the chemical...
Curated OER
Photosynthesis in a Jar
Students simulate Joseph Priestley's experiments using a bell jar. They demonstrate that oxygen is necessary for fire and animals but that given time, plants can create oxygen, allowing fires to burn and animals to breathe.

How Fire Burns
Students observe teacher demonstration, discuss Fire Triangle, examine three things that fire needs to continue burning, including fuel, oxygen, and heat, and discuss how Stop, Drop, and Roll strategy is safest method of stopping...
Curated OER
Making Oxygen
Use demonstrations to enlighten learners on oxygen's role in combustion. Use potatoes and hydrogen peroxide to increase oxygen concentration in a jar, then stick a glowing splint and a burning wad of steel wool into the newly formed...
Curated OER
Fossil Fuels: Facing the Issues
Students explore energy by researching fuel usage on Earth. In this fossil fuel instructional activity, students define fossil fuels, the energy created by burning them, and the impact on the environment when using them. Students conduct...
Curated OER
Measurement of Volume
Students measure the volume of a clear container using a candle and sand. In this measuring volume lesson plan, students time how long a candle stays lit in a clear glass container. They fill it with sand and find the volume and then use...
Curated OER
What is Fire?
Learners conduct an experiment. In this fire instructional activity, students view an experiment where they learn the conditions needed to keep a fire burning. Learners discuss the experiment and learn about the fire triangle.
Curated OER
Floating Candles
Students observe a combustion reaction and deduce the components necessary for the reaction to occur. They also identify and interpret the relationship between pressure, volume, and number of molecules for gasses. Finally, students use...
Curated OER
Chemical Changes
Second graders investigate chemical changes and reactions and will identify four characteristics that indicate a chemical change. In this chemical change lesson plan, 2nd graders perform experiments that promote chemical changes. They...
Curated OER
Fire Triangle
Students discuss what humans need to stay alive. They observe a candle that is lit and talk about candle safety and controls. They think about what a candle needs to keep burning and relate it to what people need to stay alive. They...
Curated OER
Fire Triangle in the Forest
Young scholars investigate the physical properties of fire by creating storyboards. In this elements instructional activity, students view a video clip of forest fires and identify the cause. Young scholars create large storyboards...
Curated OER
Oxygen vs. Air Pressure
Learners conduct an experiment to determine if water level is affected by a change in oxygen level or air pressure.
Curated OER
What's the Connection Between Convection and Inversion?
Ninth graders observe a simulation demonstrating the difference between convection and inversion. They explain where and when convection and inversion layers occur and how each impacts air quality, and by connection, human health.
Curated OER
The Chemistry of Fire and Other Oxidation Reactions
Young scholars explore the process of combustion.
Curated OER
Carbon Dioxide: The Heat is On
Young scholars examine the greenhouse gases affecting the atmosphere. In groups, they participate in activities in which they examine the effects of heat on the atmosphere and phytoplankton. They research how the phytoplankton differ...
