Class 8 Science Curiosity Textbook Chapter 1 Exploring the Investigative World of Science question answer
Dough rises when yeast or other leavening agents produce gases like carbon dioxide, which get trapped in the dough and cause it to expand. This is a scientific question because it involves processes like fermentation, gas production and temperature effects. It leads to investigation—how ingredients react, what conditions affect rising and how changes influence the outcome. Exploring this question teaches important scientific concepts and shows how everyday experiences can lead to deeper scientific understanding.
