Summary Burn ethanol in a jug to make a blue flame and a sound. Science content Chemistry: Chemical Changes (2, 7) Physics: Energy forms, Conservation of Energy (1, 3, 4, 5) Lessons activity is in Combustion Materials large heat proof flask or jug 95% ethanol long handled lighter safety goggles and a good distance between the activity and students Procedure Add a little ethanol to the jug. Swirl it around to coat the sides and evaporate into the volume of the flask. Ignite at the top. Discuss the chemistry of the reaction: ethanol + oxygen -> water and CO2Model the chemistry of the combustion reaction Grades taught Gr 4 Gr 5
