  • Resumen
    • Knowing the volume of evolved gases is helpful to select an optimal leavening agent for a particular application. The comparison of leavening agents, their reactions through the baking process in the modern and attractive way, is presented here. A gas pressure sensor probe was used to monitor the pressure change due to the carbon dioxide produced in the decomposition as a function of time. The experiment is simple to set up, uses nonhazardous materials, and provides students with an opportunity to engage with commonly used household products. It was conducted by over 200 high school students. Both students and teachers found the activity interesting. Students’ engagement was increased by seeing the real-world application of this activity. Most students and teachers recommended this activity to be part of the laboratory practices.
