Population Connection

  • This lesson plan provides instructions and a PDF of words to use for a word web activity that allows students to identify the many connections between a growing human population and resources, the environment, and daily life.

Teaching Tips

  • Students will use a graphic organizer to connect seemingly disparate concepts like freedom, shopping malls, and illness.
