2.2: Using Growth, Development, and Puberty – Student Edition (Human Biology)

Difficulty Level: At Grade Created by: CK-12

Begin by letting students know that they are the focus of this unit. As middle school students, most of them are approaching, experiencing, or finishing puberty. This unit will help them understand the changes that they are experiencing.

Make sure that students understand the differences between growth/development, physiological/psychological, and puberty/adolescence. Complete the Mini Activity: Puberty Brainstorm.

Introduce Activity 1-1: You Must Have Been a Beautiful Baby on the first day so students have time to bring in their pictures, or ask them a week before you begin the unit, so that you will have the bulletin board ready on the first day.

Have the students read the material on what it feels like to go through puberty. Make a decision about whether you will give each student a copy of the drawings or create an overhead for your own use. Before you introduce Activity 1-2: Examining Differences, talk with your class about the way to conduct themselves when discussing sensitive material.

Conclude by reviewing the basic changes of puberty.

A suggested response will be provided upon request. Please send an email to teachers-requests@ck12.org.

During puberty, girls' breasts grow larger and boys' testes begin to produce sperm. Why would these changes be called “development,” rather than “growth?”

Puberty Brainstorm Students create a chart that lists the physical, social, and psychological changes that have occurred since childhood.
