Next Generation Science Standards (NGSS):

• 2-LS4-1: Make observations of plants and animals to compare the diversity of life in different habitats.
• CCSS.ELA-LITERACY.RI.2.1: Ask and answer such questions as who, what, where, when, why, and how to demonstrate understanding of key details in a text.
• CCSS.ELA-LITERACY.RI.2.3: Describe the connection between a series of historical events, scientific ideas or concepts, or steps in technical procedures in a text.

Learning Objectives

• Students will identify and label parts of a jellyfish using a diagram.
• Students will improve reading comprehension by answering questions from a short informational story about jellyfish.
• Students will practice vocabulary related to marine biology and jellyfish anatomy.
• Students will demonstrate understanding of jellyfish as animals living in specific habitats.

---

Materials

• Short informational story about jellyfish (written at 2nd grade reading level)
• Worksheet with labeled diagram of a jellyfish and fill-in-the-blank parts
• Question sheet based on the story (5 questions: multiple-choice and short answer)
• Pencils/crayons
• Whiteboard or chart paper for discussion

Lesson Procedure

1. Introduction & Engagement (10 seconds)

• Briefly introduce jellyfish: “Today we’re going to learn about a fascinating sea creature called the jellyfish. Jellyfish live in the ocean and have parts that help them swim and catch food.”
• Show a simple colorful picture of a jellyfish on the board.

2. Read-Aloud: Jellyfish Story (20 seconds)

• Read aloud the short story about jellyfish (e.g., “The Jellyfish’s Life”) emphasizing key vocabulary: bell, tentacles, sting, ocean, pulse.
• Ask quick questions during reading to engage: “What do you think the jellyfish uses its tentacles for?”

3. Worksheet Activity: Labeling Parts (20 seconds)

• Distribute the worksheet with a labeled diagram and scrambled labels for jellyfish parts (bell, tentacles, mouth, sting).
• Student labels each part on the worksheet, encourages fine motor skills and understanding anatomy.
• Provide support if needed.

4. Comprehension Questions (10 seconds)

• Student answers 5 short questions about the story on the back of the worksheet:
  1. What do jellyfish use to move? (Answer: Bell)
  2. Where do jellyfish live? (Answer: Ocean)
  3. What helps jellyfish catch food? (Answer: Tentacles)
  4. True or False: Jellyfish are plants. (Answer: False)
  5. Why must we be careful around jellyfish? (Answer: They can sting.)

---

Assessment

• Review worksheet labeling for accuracy.
• Review comprehension questions for understanding of core concepts.
• Observe student’s ability to answer “who, what, where, why” questions consistent with CCSS RL.2.1.

---

Extension/Reflection (Optional for Future Use)

• Create a simple “Jellyfish Facts” poster using drawings and labels.
• Discuss other ocean animals that live with jellyfish.

---

Teacher Notes

• Keep pace brisk but supportive; 2nd graders may need quick prompts to stay focused.
• Use colorful images and repetitive vocabulary for engagement.
• Worksheet and story are designed for individual work but can be adapted for pairs.

Example Short Story for Read-Aloud (to be read in ~20 seconds)

The Jellyfish’s Life

The jellyfish lives in the ocean. It has a bell on top that helps it move up and down. Under the bell are long, soft tentacles. The tentacles catch tiny animals that the jellyfish eats. Sometimes, the jellyfish’s tentacles can sting, so it is best to look but not touch! Jellyfish pulse their bell gently to swim through the water.

Worksheet Sample

Part 1: Label the parts of the jellyfish (write or draw lines):

• Bell
• Tentacles
• Mouth
• Sting

Part 2: Answer the questions from the story (circle or write):

1. What helps the jellyfish move?
2. Where does it live?
3. What do the tentacles do?
4. True or false: Jellyfish are plants.
5. Why is it important to be careful near a jellyfish?
