Key Questions


  • Describe the difference between the small intestine and the large intestine.
  • What happens as food travels through the small intestine?
  • What are villi? How do they help with digestion?
  • The author says undigested leftovers end up in the large intestine. What does it mean if something is undigested?
  • What is poop? Why is poop important?
  • How does the diagram contribute to our understanding of the digestive system?
  • What does the author teach about in the section "Large Intestine"?
  • What is the main topic of this section of the text? How do you know?







For many the topic of this text will be silly or disgusting. At the beginning of class make sure to set a serious tone, explaining that digestion and poop are an incredibly important part of keeping our bodies healthy and functioning properly, and that as second graders they are mature enough to learn about it.
