Educational worksheet showing physical changes during puberty for males and females.

Problem Overview:

The task is to label the images of a male and a female with puberty-related changes. Some changes apply to both genders, while others are specific to males or females. The goal is to match the correct changes to the appropriate parts of the body.

Solution Approach:

1. Identify Gender-Specific Changes:
- Female-specific changes: Menstrual cycle starts, breasts develop, hips widen, vaginal discharge is produced.
- Male-specific changes: Testes start to produce sperm cells, increased muscle growth, facial hair grows, voice deepens.

2. Identify Common Changes:
- Growth spurts, pubic hair grows, underarm hair grows, mood changes, body odor becomes stronger, shoulder widens, pimples or acne.

3. Label the Images:
