Lesson Plan: Stars - Science

Subject:  Science 

Grade: 3 

Lesson Objective: To learn about how a star is formed and then answer questions related to that information 

Standard:  CCSS.ELA-LITERACY.RI.3.1- Ask and answer questions to demonstrate understanding of a text, referring explicitly to the text as the basis for the answers. 




  • How many stars do you think there are?  Where do you think they came from?  (Allow the students to answer.) 



  • There are billions of stars in the universe and most have been around for millions of years! 

  • It is a lot of fun to look up at the sky at night and see the stars.  It is also fun to find constellations when we are looking at the stars.   

  • People have used the stars for hundreds of years to help them to navigate or get around.  Stars have also been used to help scientists figure out how planets Earth, move. 

  • Today, we are going to be learning about how a star is formed.  It takes about ten million years for a star to form.  That is a really long time! 

  • Once the star is formed, it goes through a life cycle.  After it is formed, it is around for millions to billions of years depending on how big it is. 

  • Once the star has reached the end of its life, it burns out.  If the star is a very large star, it will expand and then burn out.  If it is a small star, it just burns out and then it is not there anymore.  This also takes millions of years to happen.   

  • Stars are so interesting and there is so much to learn about them.  

  • You are going to read about how a star is formed.  You are then going to answer questions about what you have read. 

  • Does anyone have any questions? 



  • Who would like to share your answers?  (Allow the students to share)
