Worm Life Cycle

Overview

This 45-minute lesson will engage kindergarten students working on developing their understanding of the worm life cycle as part of the unit Wiggly Worm Wonders (Lesson 3 of 10). Through storytime, interactive technology, and hands-on activities, students will identify and sequence the stages of a worm's life cycle, learning about worm habitats and development.

Learning Goal

Students will be able to identify and sequence the stages of the worm life cycle, demonstrating understanding through discussion and a cut-and-paste activity.

California Preschool Foundations & CA K-3 Science Framework Alignment

Framework	Standard or Foundation	Description
CA Preschool Foundations	Life Science	Observe and describe characteristics and basic needs of living things; understand life cycles and growth.
CA Next Generation Science Standards (K-PS3-1, K-LS1-1, K-LS1-2)	K-ESS3-1	Use observations to describe patterns and cycles in nature; understand how living organisms grow and change.
CA Common Core ELA (Kindergarten)	Reading: Informational Text	With prompting, identify the main topic and retell key details from informational text (CA ELA RI.K.2).

Materials

• Picture book or short story about worms and their life cycle (age-appropriate, illustrative)
• Interactive Google Slides presentation on worm life cycle stages with images and simple questions
• Cut-and-paste activity sheets with 4 life cycle stage images (egg, hatchling, juvenile worm, adult worm)
• Scissors, glue sticks for each student
• Large laminated chart of worm life cycle for demonstration
• Labeled images for ELL students (with simple words: Egg, Baby Worm, Young Worm, Adult Worm)
• Whiteboard and markers

Lesson Procedure

1. Introduction & Attendance (5 minutes)

• Greet students and briefly review what they learned about worms in previous lessons (e.g., what worms eat, where they live).
• Set context: "Today we're going to learn how worms grow and change!"

2. Story Time: Worm Life Cycle (10 minutes)

• Read aloud a short story about worm life cycle — emphasising the life stages and habitats.
• Pause to ask simple comprehension questions (“What is this?” “Where do worms live?” “What happens next?”) to check understanding.
• For ELL students, show labeled picture cards as you read.

3. Interactive Google Slides Presentation (10 minutes)

• Project the slides and guide the class through the worm life cycle stages, asking students to identify and sequence.
• Include activities like "Point to the egg," "Which comes first, hatchling or adult?" and simple drag-and-drop matching on the slides, if possible.
• Use the large laminated chart to physically point and reinforce sequence.

4. Cut-and-Paste Activity: Life Cycle Sequencing (15 minutes)

• Hand out cut-and-paste sheets with worm life cycle images and glue sticks.
• Explain the activity: Students will cut out pictures and paste them in order from egg to adult worm.
• Provide labeled image versions of the activity sheets for ELL students to support language comprehension.
• Circulate and assist students who need help cutting or sequencing.

5. Sharing and Review (5 minutes)

• Invite individual students to share their sequenced life cycle with the class.
• Reinforce correct sequencing and vocabulary.
• Summarize key points about worm growth and habitat.

Differentiation & Accommodations

• For ELL learners: Use labeled images, repeat vocabulary often, pair students with bilingual peers if possible.
• For students with fine motor challenges: Provide pre-cut images or allow drawing/sequencing with stickers instead of cutting.
• For advanced learners: Ask them to explain why worms need their habitats or what worms might eat at different stages.

---

Assessment

• Informal observation during Google Slides participation and cut-and-paste activity: Are students correctly sequencing life cycle stages?
• ELL students’ use of vocabulary labels and ability to point to correct stages.
• Short class discussion recap to verify comprehension.

---

Reflection and Extension Ideas

• Create a classroom worm habitat observation bin to monitor a live worm’s growth over the next week(s).
• Integrate sensory play with model worms made of clay to role-play life cycle stages.
• Invite students to compose a simple “Worm Life Cycle” song or movements to strengthen memory of sequencing.

By combining interactive read-aloud, technology, and hands-on art activities aligned with CA standards, this lesson ensures diverse learners develop foundational life science understanding about worms with language support and sensory engagement.
