Ethanol Activity 4
This is a hands-on chemistry lab activity in which student pairs investigate and compare the efficiency and environmental impact of two combustible fuels—kerosene and ethanol. Using a LabQuest2 temperature sensor, bromthymol blue indicator, and sodium hydroxide, students measure heat released, carbon dioxide emissions, and particulate matter (soot), then collect qualitative and quantitative data to evaluate which fuel is more energy efficient and environmentally friendly.
