Cog’s 7-minute video, Carbon from Campfires, casts light on wood fires. It starts with plant cell walls made of complex carbohydrates like cellulose that burn to release carbon dioxide (CO2), water, heat, and light. We examine the three legs of the fire triangle and discover that wood burns indirectly. Our final look at wood points out that whether cellulose is digested, decomposed, or combusted, it is broken down into CO2, water, and energy.The Teacher Resource page gives links to information t
