My Topic Activity
Lesson 1: Observing the Life Cycle of Pumpkins
Overview
Students observe growth and decomposition while learning
about and growing pumpkins. This unit is
tied to both literacy and math lessons during the pumpkin season. It provides a
great opportunity to bring nonfiction literature to the read-aloud time and
introduce your students to facts about the world around them. Students will learn about the life cycle of
pumpkins from nonfiction books and will practice early reading skills in a
shared reading related to the unit.
Objective
Students will:
1. Learn about the life cycle of a pumpkin.
2. Observe growth and decomposition.
3. Learn where food comes from.
4. Practice early reading skills through a shared reading.
Materials:
•Pumpkin Circle: The Story of a Garden by George Levenson,
and other books that you've used to teach life cycles
•Chart paper for recording student observations during the
read-aloud
•Pots, soil
•Pumpkin seeds
•One large piece of a pumpkin
•Jar
•Student Observation Journals (PDF)
•Five Little Pumpkins by Iris Van Rynbach
•Pocket chart for shared reading
•Sentence strips
Set Up and Prepare:
1. Print student journals, one per student.
2. Make sentence strips with the text from Five Little
Pumpkins and mount it in the pocket chart for the shared reading (as shown in
the photo above).
Directions:
Part I: Nonfiction Reading
Step 1: Ask students questions about where pumpkins (and
other foods) come from. Then tell students you will read Pumpkin Circle: The
Story of a Garden to help us learn about where pumpkins come from and how they
grow.
Step 2: Read Pumpkin Circle: The Story of a Garden aloud to
the class. Stop to discuss what students notice and learn about pumpkin growth.
As students recount the story, chart the sequence of the pumpkins' growth.
Step 3: To grow your students' understanding, follow up this
reading with other books that teach life cycles and plant growth.
Part II: Planting Pumpkins
Step 4: Review with students what they learned about a
pumpkin's growth and tell them they’ll get to grow a pumpkin plant in class.
Then give each student a pot, some potting soil, and several seeds to plant.
Step 5: Show the students how to dig a hole in the soil and
plant their seeds. Guide them when watering their seeds. You’ll need to water
the pots and put them in the sun daily.
Part III: Observing Growth and Decay
Note: You may want to start this part when the seeds are
just starting to sprout.
Step 6: Discuss with students what they do at home with old
fruits and vegetables. What did they learn in Pumpkin Circle: The Story of a
Garden about pumpkins that get old and mushy? (Introduce the words
"decay" and "decompose.") Ask them: Have they ever seen
fruit that is starting to decay, or get old and yucky?
Step 7: Tell students that you will watch a pumpkin grow,
from the beginning to the end of the pumpkin life cycle. Tell them they will
watch their potted pumpkins sprout and grow, then show students the piece of
fully-grown pumpkin and tell them that we’re going to keep it in a jar (so it
won’t smell) and watch the pumpkin grow old and decay.
Step 8: Pass out the Student Observation Journals (PDF).
Tell students to record (with pictures or words) what they see as they take
care of their seeds and watch the piece of pumpkin decompose. Look for ways to
connect the students’ observations to books you are reading and things they are
learning. Students will take their plants home after they have grown to a
predetermined height.
Part IV: Shared Reading
Step 9: Shared readings are a non-threatening environment
for early readers to practice tracking, fluency, phrasing, and sight words. The
story Five Little Pumpkins by Iris Van Rynbach is a great book to use as a
shared reading with this unit. (As the students become familiar with the text,
I use it for skill-based mini-lessons — see below for an example.) Take out the
pocket chart with sentence strips that you prepared for the Five Little
Pumpkins.
Step 10: Read the Five Little Pumpkins poem from the
sentence strips. While reading, point to the words with a long pointer.
Step 11: Once the students are comfortable with the poem,
let volunteers lead the reading with the pointer. Optional: Have the students
make pumpkin puppets and act out the poem as you read it together.
Reproducible Worksheets
Student Observation Journals
Supporting All Learners:
Encourage students who don’t normally raise their hand
during discussions. Give them the opportunity to read the poem to you or the
class -- as long as they feel comfortable doing so. Allow sufficient wait time
for students to gather their thoughts and formulate their answers. Some
students will be encouraged to read the pocket charts when the pointers are a
different shape, size, or perhaps something fun like a large hand.
Lesson Extensions:
Take students to see a real pumpkin patch with a field trip.
Home Connection:
Have parents talk with their children about the food they
buy at the grocery store. Where does
that food come from? How does it grow? Perhaps they can find smaller and larger
pumpkins at the store.
Assignments:
Students will participate in a shared reading of a poem, and
discuss the stages of a pumpkin’s growth.
Evaluation:
1. Are the students incorporating things learned from the
read-aloud into their thinking?
2. Were they interested in the topic?
3. Did they go to the pocket charts on their own time and
read them?
4. Do you see the reading skills practiced during shared
reading when students are reading independently?
Assess Students:
1. Did students participate in discussions?
2. Do students participate in the shared reading?
