Lesson Objective: To learn about the life cycle of a plant

Common Core StandardCCSS.ELA-LITERACY.RI.1.1- Ask and answer questions about key details in a text.




  • Where do new plants come from?  (Allow the students to answer.)



  • New plants grow from seeds.  We have talked about how there are many different types of plants such as fruits and vegetable plants, flowers, grass, bushes and trees. 
  • All of those types of plants have seeds in or on some part of them.  The seeds fall to the ground and then they start to grow into new plants.
  • Some of you may have seen seed pods from flowers or trees on the ground when you went to a park or went for a walk in the woods. 
  • Different plants grow seeds in different places.  Grass grows seeds at the top when it gets really long.  Most people do not let their grass get long enough to grow seeds, but if you look in a field of long grass, you can see the seeds at the top.
  • Any type of plant that has flowers has seeds.  The seeds grow inside of the flower and when the flower dies or falls off, the seeds fall to the ground.
  • Trees and bushes that do not have flowers grow seeds in seed pods that fall to the ground.  Some seed pods are nuts and some are pinecones.
  • Plants that grow fruits and vegetables have seed inside the fruit and vegetables. 
  • The seeds from the plants end up on the ground and some of them start to grow.  They first grow roots, then a stem and then the leaves grow. 
  • This usually happens once a year.  The seeds end up on the ground at the end of the summer or in the fall.  The seeds are on the ground all winter and then in the spring, they start to grow.  This is called the life cycle of a plant.
  • You are going to be looking at a diagram of the life cycle of a sunflower, reading a little about the life cycle of plants and then answering questions.
  • Does anyone have any questions?



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