This lesson accompanies the BrainPOP topic Forces, and supports the standard of providing evidence of the effects of balanced and unbalanced forces on the motion of an object. Students demonstrate understanding through a variety of projects.


Put a tennis ball and a ping pong ball on a flat surface. Ask students:

  • What do you predict will happen if I push both balls with the same force? 
  • Which ball do you think will go further? Why do you think this?

Push the balls with the same force. Ask students:

  •  Were your predictions correct? 
  • What other forces, besides your push, are acting on the balls? 


  • Read the description on the Forces topic page.
  • Play the Movie, pausing to check for understanding. 
  • Have students read one of the three 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 Forces Challenge and Quiz, applying essential literacy skills while demonstrating what they learned about this topic.


Students express what they learned about forces 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 a sportscaster. Create a newscast answering this question: How do different forces impact a baseball’s movement when a player hits a home run?
  • Make-a-Map: Compare and contrast the forces that impact  riding a bike uphill, downhill, and on a flat surface.  
  • Creative Coding: Code a game challenging players to sort examples by balanced or unbalanced forces. 
  • Primary Source Activity: Analyze video footage of a roller coaster in motion, and cite evidence to answer the questions.
