This RSE pupil-facing video introduces the physical and emotional changes that occur during puberty. It explains the role of hormones and how they drive the transformation from childhood to adulthood, including changes in both male and female bodies. The video covers the development of secondary sexual characteristics, such as growth spurts, changes in voice, body hair, and menstruation. It also addresses the emotional impact of puberty, including mood swings and body image concerns, reassuring children that these changes are normal and experienced by everyone, albeit at different times.
