Exploring Physical and Chemical Changes through Lemonade Making

The video tutorial takes place in a kitchen setting, where the instructor demonstrates how to make lemonade while exploring the concepts of physical and chemical changes. The tutorial includes lighting a candle to discuss melting and burning, boiling water to observe evaporation, dissolving sugar in water, squeezing lemons for juice, and mixing ingredients. The video concludes with a glow experiment, encouraging viewers to identify the types of changes occurring throughout the process.
