Bear Life Cycle

Grade 5 Science – British Columbia Curriculum

---

Overview

This 60-minute lesson introduces Grade 5 students to the life cycle of bears. It aligns with the British Columbia Science Curriculum, focusing on growth, development, and survival of living things (Grade 5 - Life Sciences).

---

Curriculum Alignment

Curricular Competencies:

• Communicating and representing: Share observations and ideas about life cycles using oral and visual methods.
• Questioning and predicting: Pose questions related to how bears grow and survive throughout their life stages.
• Planning and conducting: Participate in hands-on activities to explore life stages.
• Processing and analysing data and information: Sequence life cycle stages based on observations.

Content:

• Describe growth and changes in animals during their life cycles.
• Understand the concepts of survival and environmental adaptation.

(Classified under BC Science Curriculum: Grade 5, Life Sciences – Growth and Changes in Animals; Big Idea: Growth and changes in living things happen in predictable ways.)

Learning Objectives

By the end of this lesson, students will be able to:

1. Identify and describe the five main stages in a bear’s life cycle: birth, infancy, juvenile, adulthood, and hibernation.
2. Explain how bears develop and survive through these stages.
3. Illustrate the bear life cycle in sequence using creative visuals.
4. Demonstrate understanding of the connections between the bear’s life cycle and its environment.

Lesson Timeline

Time (minutes)	Activity Description	Purpose
0 – 10	Engage / Introduction Show images of bears in different life stages. Ask students what they notice and know about bears. Take quick brainstorm on board.	Activate prior knowledge & curiosity
10 – 20	Teach / Direct Instruction Explain the five stages of the bear life cycle with visuals. Highlight survival strategies like hibernation.	Build conceptual understanding
20 – 35	Explore / Group Activity In pairs, students receive life cycle sequencing cards to arrange in correct order. Then, they work on poster boards to illustrate each stage, adding vocabulary notes.	Collaborative learning, reinforce sequence & vocabulary
35 – 50	Explain / Sharing and Discussion Pairs present their life cycle posters to the class. Discuss connections to habitat and survival. Use questioning to deepen understanding.	Develop communication skills & critical thinking
50 – 58	Elaborate / Individual Reflection Complete the “Bear Life Cycle” worksheet — students draw and write brief descriptions of each stage.	Individual processing & evidence of learning
58 – 60	Evaluate / Exit Ticket On sticky notes, students write one new fact they learned and one question they still have. Collect for assessment and follow-up.	Quick formative assessment & engagement check

Detailed Activity Descriptions

1. Introduction & Engagement (10 mins)

• Show large colourful photographs of a bear cub, juvenile, adult bear, and a bear in hibernation.
• Invite students to share what they notice or already know.
• Record ideas on whiteboard under headings: “What we know” and “What we want to know”.

2. Direct Instruction – Life Cycle Stages (10 mins)

• Using visuals, describe each stage:

  • Birth: Cubs born in dens during winter.
  • Infancy: Cubs nurse and learn survival skills.
  • Juvenile: Young bears explore and develop independence.
  • Adult: Mature bears reproduce and prepare for winter.
  • Hibernation: Bears sleep through winter to conserve energy.

• Emphasise how each stage helps bears survive in their environment.

3. Group Sequencing and Illustration (15 mins)

• Hand out life cycle cards to pairs (5 cards each—one per stage).
• Students arrange cards in order.
• Using poster boards and art supplies, create a life cycle illustration.
• Add quick notes or keywords about each stage to reinforce vocabulary.

4. Sharing and Discussion (15 mins)

• Each pair briefly presents their poster.
• Prompt questions:
  • Why is hibernation important?
  • How do baby bears learn to survive?
  • What happens if a stage is disrupted?
• Connect answers back to survival and adaptation concepts.

5. Individual Worksheet (8 mins)

• Students complete the worksheet illustrating the cycle and describing each stage in their own words.
• This supports assessment of individual understanding.

6. Exit Ticket (2 mins)

• Each student writes on a sticky note:
  • One fact they learned.
  • One question they still have.
• Collect sticky notes for ongoing assessment and future lesson planning.

Assessment Methods

• Formative: Observation during group sequencing and presentation; participation in discussions.
• Summative: Completed worksheet showing understanding of the life cycle sequence and characteristics of each stage.
• Exit Tickets: Provide insight into individual learning and remaining misconceptions.

Assessment will focus on:

• Ability to sequence life cycle stages correctly.
• Use of vocabulary in oral and written forms.
• Understanding connections between life stages and survival needs.
• Engagement and collaboration skills.

---

Adaptations and Extensions

• For diverse learners: Provide illustrated cards with fewer words or labelled drawings; pair stronger readers with peers for support.
• Extension for interested students: Research different bear species and compare their life cycles.
• Cross-curricular opportunity: Write a creative story from the perspective of a bear cub experiencing the different life cycle stages.

---

Teacher Reflection

• How effectively did students sequence and represent the life cycle stages?
• Were students able to connect survival and adaptation vocabulary to their drawings?
• Did the exit tickets reveal any common misconceptions to target in future lessons?

This lesson balances inquiry, collaboration, and individual reflection, strictly aligning with the British Columbia Grade 5 Science curriculum. It encourages curiosity about nature, clear communication, and deep understanding of animal life cycles within an age-appropriate, engaging format.
