This lesson accompanies the BrainPOP topic Body Systems, and supports the standard of understanding how the body is made up of interacting subsystems composed of groups of cells. Students demonstrate understanding through a variety of projects.


Ask students: 

  • How do parts of the body work together when you exercise or play a sport?
  • What do you think happens inside the body after you eat a meal?


  • Read the description on the Body Systems topic page.
  • Play the Movie, pausing to check for understanding. 
  • Have students read one of the Related Reading articles. Partner them with someone who read a different article to share what they learned with each other.

Step 3: APPLY and ASSESS

Students take the Body Systems Challenge and Quiz, applying essential literacy skills while demonstrating what they learned about this topic


Students express what they learned about body systems while practicing essential literacy skills with one or more of the following activities. Differentiate by assigning ones that meet individual student needs.

  • Make-a-Movie: Imagine you are in a microscopic car traveling through the human body. Create a virtual tour of one of the body systems.
  • Make-a-Map: Create a flowchart showing how the organs of the digestive system work together to process nutrients. 
  • Creative Coding: Code a sorting game to categorize organs into their different body systems.
