Exploring Cell Types

Overview

This 60-minute lesson introduces Year 6 students to the fundamental concepts of cells, focusing on prokaryotic and eukaryotic cells, and the differences between animal and plant cells. The lesson aligns with the National Curriculum for Science in England, specifically addressing statements under the "Living things and their habitats" and "Animals, including humans" sections for Key Stage 2.

Curriculum Links

• National Curriculum Science KS2 (Year 6):
  • Biology - Living Things and Their Habitats:
    • Describe how living things are classified into broad groups according to common observable characteristics and based on similarities and differences, including microorganisms, plants and animals.
  • Biology - Animals, including Humans:
    • Identify and name the main parts of the human circulatory system, and describe the functions of the heart, blood vessels and blood. (Supports understanding of cells in context of larger systems.)
  • Working Scientifically:
    • Use straightforward scientific evidence to answer questions or to support their findings.
    • Use classification keys to help group, identify and name a variety of living things.

Learning Objectives

By the end of the lesson, students will:

1. Define what a cell is and understand that all living things are made of cells.
2. Identify the main differences between prokaryotic and eukaryotic cells.
3. Recognise and describe the structure and functions of animal and plant cells.
4. Compare and contrast animal and plant cells by noting their differences.
5. Use vocabulary related to cells accurately (e.g., nucleus, cytoplasm, cell membrane, chloroplasts, cell wall).

Resources Needed

• Projector or interactive whiteboard for visuals
• Pre-prepared printed diagrams/posters of prokaryotic and eukaryotic cells, plant and animal cells
• Microscopes (if available) or images of real cells under microscope
• Blank cell outline worksheets for annotation
• Colouring pencils/markers
• 'Cell fact cards' (small cards with key features and functions)

Timetable and Activities

Time	Activity	Description	Differentiation/Support
0-5 mins	Starter - What is a Cell?	Brief whole-class discussion: Ask students what they know about cells. Explain all living things are made of cells. Show a simple animation or picture of cells to engage students.	Use visuals and encourage sharing prior knowledge.
5-15 mins	Exploration - Prokaryotic vs Eukaryotic Cells	Present clear diagrams comparing prokaryotic (simple, no nucleus) and eukaryotic cells (complex, with nucleus). Use analogy: "Prokaryotes are like tiny stores with no manager (nucleus), eukaryotes have a manager." Show examples (bacteria as prokaryotes, plants and animals as eukaryotes). Ask students to sort ‘cell fact cards’ into groups.	Use visual sorting activity to aid kinesthetic learners. Provide sentence starters for lower ability.
15-30 mins	Interactive Task - Animal vs Plant Cell Structure	Show labelled diagrams of animal and plant cells. Discuss key organelles and their functions: nucleus, cell membrane, cytoplasm common to both; plant cells have cell walls, chloroplasts, and large vacuoles. Use an identical blank outline of cells worksheet for students to label and colour. Play “Cell Function Match-Up”: match organelle names to their functions.	Provide completed diagram for less confident pupils to reference; extension task for higher ability to write sentences explaining cell functions.
30-40 mins	Hands-On Challenge - Build a Cell Model	In small groups (4-5), students create a simple 3D model of either an animal or a plant cell using craft materials (playdough, pipe cleaners, paper). Each model must include labelled organelles. Groups present their models explaining the function of at least 3 parts.	Mixed-ability groups promote peer support. Provide scaffolding charts.
40-50 mins	Class Discussion - Comparing Cells	Use a Venn diagram on board to compare animal and plant cells. Students contribute by calling out differences and similarities based on learning and models. Teacher clarifies and summarises key points.	Visual learners benefit from diagram; discussion supports oral learners.
50-60 mins	Plenary & Assessment - Quick Quiz & Reflect	Conduct a short quiz (5 quick questions) on Kahoot or paper quiz to assess understanding. Example questions: “What is the function of the nucleus?” “Name one difference between prokaryotic and eukaryotic cells.” Conclude with ‘Think-Pair-Share’: students say one new thing they learned and one thing they want to know more about.	Quiz can be oral or written to suit needs; peer discussion enhances confidence.

Assessment Ideas

• Formative: Teacher observations during sorting and model activities, questioning during discussion.
• Summative:
  • Completed labelled cell diagrams accurately showing plant/animal cell differences.
  • Quick quiz results reflecting understanding of cell types and properties.
  • Verbal explanations during presentations of cell models.
• Extension: Written paragraph comparing animal and plant cells using key vocabulary and explaining why cells are important.
• Support: Sentence prompts or partially labelled diagrams for lower ability learners.

---

Differentiation and Inclusion

• Visual aids, models, and hands-on activities support different learning styles.
• Group work encourages peer mentoring.
• Scaffolded worksheets and sentence starters for learners who need more support.
• Oral questioning and assessment for learners with writing challenges.

---

Teacher Reflection Prompts

• Did the students demonstrate clear understanding of prokaryotic and eukaryotic cells?
• Were learners able to use correct scientific vocabulary confidently?
• How effectively did the model-making consolidate knowledge?
• Were all learners engaged through differentiated tasks?

Homework Suggestion

Research and bring pictures or information about a specific microorganism (prokaryotic cell) or a plant/animal cell type to share in the next lesson.
