Lesson Plan: Life Cycle

Subject:  Science

Grade: 2

Lesson Objective: To learn about where frogs life, the life cycle of frogs and then answer questions about the life cycle

Standard:  2-LS4-1: Make observations of plants and animals to compare the diversity of life in different habitats.




  • Have you ever seen a frog?  What do you know about them?  (Allow the students to answer.)



  • There are many different types of frogs.  Frogs are animals that are in amphibians.  They live the first part of their lives in the water and the last part of their lives on land. 
  • All of that is part of their life cycle.  A life cycle shows the changes that happen to a living thing as it moves through its life.
  • Some living things, like plants and butterflies, go through many changes during their life cycle that change the way that they look.  Other living things, like people, only get bigger.
  • The life cycle of a person starts when you are a baby.  You are born as a baby, then you grow into a child and then an adult.  As an adult, you are able to have a baby and the life cycle starts again.
  • People look the same from the time they are born until they grow to be adults.  We have all of the same body parts when you are born that you have when you grow up. 
  • Did you know that there are some animals that have different body parts when they are born and when they grow up?
  • Raise your hand if you think that you can describe the life cycle of a frog.  (Allow the students to answer).
  • You are going to read about the life cycle of a frog, just like the frog in The Frog Prince.
  • 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)
