Ants in Action

Learning Objectives

By the end of this 60-minute session, Year 3 students will be able to:

• Describe the life cycle of an ant using correct vocabulary (egg, larva, pupa, adult).
• Identify and explain basic ant behaviours such as communication, foraging, and nest building.
• Recognise what ants typically eat and explain how ants find their food.
• Work collaboratively to conduct simple research and make observations.

National Curriculum Links (England, Year 3 - Animals including humans & Living things and their habitats)

• SCIENCE - Working scientifically:

  • Gather, record, classify and present data in a variety of ways to help answer questions.
  • Use straightforward scientific evidence to answer questions or to support their findings.

• SCIENCE - Animals, including humans:

  • Identify that animals, including humans, have offspring which grow into adults.

• SCIENCE - Living things and their habitats:

  • Understand the difference between things that are living, dead, and things that have never been alive.
  • Explore and compare the life cycles of different living things.
  • Identify and describe the basic needs of animals for survival (food, water, air).

Materials Needed

• Large printed diagram of an ant life cycle (egg → larva → pupa → adult)
• Collection of colourful photos or laminated cards showing different ant behaviours and foods
• Magnifying glasses (1 per pair)
• Small clear containers or plastic observation boxes with live ants (alternatively, videos of ant colonies for virtual observation)
• Paper and coloured pencils for drawing
• Large whiteboard or flip chart with markers
• Sticky notes or small index cards for recording observations
• Printed fact sheets or simple information booklets about ants
• Plastic trays to keep materials organised
• Timer or stopwatch for activity pacing

Lesson Breakdown

1. Introduction & Engagement (10 minutes)

• Starter question: "What do you already know about ants?"
  • Invite quick responses and write ideas on the whiteboard under headings: Life cycle, Behaviour, Food.
• Show the large ant life cycle diagram and briefly introduce each stage using simple descriptive language.
• Explain how ants live in colonies and have special jobs.

Teacher prompt: “Today, we’re going to be ant experts! We’ll learn how ants live, what they eat, how they behave, and even get to observe some live ants.”

---

2. Ant Life Cycle Exploration (15 minutes)

• Divide the class into 5 groups of 5 students.
• Provide each group with a set of life cycle cards shuffled randomly (egg, larva, pupa, adult).
• Task: Put the cards in the correct order and explain each stage to their group members using the fact sheets.
• Ask each group to share their ordering and explanation with the class.
• Teacher reinforces vocabulary and stages, correcting gently where needed.

Key questions:

• "What happens during the larva stage?"
• "Which stage is the ant fully grown?"

---

3. Ant Behaviour and Food Discussion (10 minutes)

• Using the photo cards, facilitate a guided whole-class discussion spotlighting:
  • Ant communication through pheromones and antennae touching.
  • Foraging behaviours: how ants work together to find and carry food.
  • Nest building and caring for young ants.
• Highlight the variety in ant diets: sugar, other insects, leaves, seeds (depending on species).
• Introduce the idea of ants as part of the ecosystem and how their behaviour helps their colony survive.

---

4. Hands-On Observation Activity (15 minutes)

• Organise paired students with magnifying glasses and observation boxes (or videos if live ants unavailable).
• Task: Observe and note any ant movements or behaviours.
• If available, set up simple trails with sugar or small food bits near the ants to observe foraging behaviour.
• Students record their observations, draw the ants focusing on details like legs, antennae, and behaviour they see.
• Teacher circulates to support observations and ask probing questions:
  • What are the ants doing?
  • How do they move?
  • Are more ants coming or going from the food?

---

5. Reflection and Assessment (10 minutes)

• Bring the class back together and invite volunteers to share their drawings and observations.
• Use a quick quiz or oral Q&A to assess:
  • Can you name the ant stages?
  • What is one thing ants do to help their colony?
  • What kind of food do ants like?
• Provide a short worksheet with 3-4 simple questions matching the objectives for those who finish early or for evidence gathering.
• Set extension challenge (optional): Find out more about other insects and their life cycles at home or in the school grounds.

---

Assessment Suggestions

• Formative: Group life cycle ordering and explanations, class discussions, observation notes and drawings.
• Summative: Completed worksheet answers and verbal quiz responses aligned to objectives.
• Peer Assessment: Encourage pairs to discuss their drawings and observations, giving feedback on details noticed.
• Teacher observations: During activities, check scientific vocabulary use and understanding of life cycle stages, behaviours, and diet.

---

Adaptations & Extensions

• For lower ability learners, provide labelled life cycle cards and more guided questions during observation.
• For higher ability learners, add a simple classification challenge comparing ants with other insects or explore ant role diversity (workers, queen, soldiers).
• Consider a cross-curricular link by writing a short diary entry from the perspective of an ant or creating a mini poster about what ants eat and why.

This lesson plan provides a vibrant, hands-on, and curriculum-aligned approach to learning about ants that will excite Year 3 pupils and develop their scientific thinking and observational skills.
