National Agricultural Literacy Curriculum Matrix
Sunflower Life Cycles
K - 2
Students will learn about the growth and development of sunflowers, identify how sunflower seeds are used, and make a paper plate sunflower illustrating the life cycle of the sunflower.
- Small white paper plates – one per student
- Seed to Seed Cycle diagrams copied on orange or yellow paper – one per student
- Large craft sticks or popsicle sticks – one per student
- These can be purchased at craft stores – most sizes will work for this activity
- Sunflower seeds – at least 6 per student
- Green paper, cut into 1” pieces
- Sunflower heads or pictures of sunflower heads
- Glue and/or Tape
- Sunflower House be Eve Bunting

life cycle: the stages a living thing goes through in its life
Did you know? (Ag Facts)
- Sunflowers are primarily grown in North and South Dakota. Several other states, such as Minnesota and California, also produce sunflowers.
- Kansas is called the Sunflower State!
- The average yield of sunflower seeds is 1,513 pounds per acre.
Background Agricultural Connections
Interest Approach – Engagement
- Tell students that you are going to give them some clues and that you want them to guess what kind of flower you are thinking of. Use all or some of these clues:
- This flower has a green stem and leaves.
- The petals of this flower are usually yellow.
- This flower can be more than 10 feet tall when it's full grown.
- This flower produces seeds that sometimes we like to eat.
- "What flower is it? (A sunflower!)
Activity 1: Sunflower Lifecycle
- Read the book, Sunflower House, by Eve Bunting to the students. As you read, Discuss with students the meaning of a “life cycle.” Point out the steps of the sunflower lifecycle as you read the story.
- Show students the Sunflower Cycle pictures. Show the students an actual sunflower head with the seeds inside if you can, but if not, use the pictures provided with this lesson. Go through each step of the cycle. Place the pictures on the board with tape or a magnet and leave them for the next activity.
Activity 2: Paper Plate Sunflowers
- Distribute the activity supplies.
- Glue the Seed to Seed Cycle in the middle of the paper plate, and set aside.
- Ask students what the first step in the Seed Cycle is (seed). Have students glue one sunflower seed about 1” up the craft stick, as if they were planting a seed in the ground and the stick is the stem that would grow from the seed.
- Ask students what the next step in the cycle is (sprout). Talk with them about what is needed for a seed to germinate. Have students draw roots on their craft stick below the seed with the brown crayon.
- Ask students what the next step is (grow). As the stems and leaves begin to grow, have students cut out leaves from the green paper and glue them to the stick above the seed.
- Ask students what step 4 is (flower). Have them color the white paper plate around the Seed to Seed Cycle. Use scissors to snip the plate edges to the center circle to create flower petals.
- Talk with students about step 5 (fruit). Students should glue sunflower seeds to the center of the Seed to Seed Cycle.
- Tape or glue the paper plate flower to the craft stick.
Concept Elaboration and Evaluation
After conducting these activities, review and summarize the following key concepts:
- Sunflowers are grown by farmers for the seeds and oil they produce.
- The life cycle of a sunflower begins and ends with a seed.
Read the book, "Seed, Soil, Sun: Earth's Recipe for Food" by Cris Peterson.
Have students work through the life cycle beginning at different starting points. You could act out each stage and play charades play pictionaryand draw each stage to review and check for understanding.
