Jurassic Period Introduction

Overview

This 60-minute lesson introduces Year 5 students to the Jurassic period within Earth’s history. It builds foundational understanding of geological timescales, the environment of the Jurassic era, and the dinosaurs that lived then. The lesson combines visual, auditory, and kinesthetic activities aligned with The National Curriculum for England Science programme of study for Key Stage 2, specifically focusing on understanding changes in the environment over time and the interrelationship of living things.

Science: Key Stage 2 (Years 3-6)

• Pupils should be taught to:
  • describe the differences in the life cycles of a mammal, an amphibian, an insect and a bird (relevant for understanding life stages)
  • recognise that living things have changed over time and that fossils provide information about living things that inhabited the Earth millions of years ago
  • construct and interpret a variety of food chains, identifying producers, predators and prey (linked for later lessons within the unit)
  • describe the changes as humans develop to old age (to contrast past creatures with today).

History:

• Pupils should develop an awareness of the past, using common words and phrases relating to the passing of time

Geography:

• Use maps, atlases and digital software to locate countries and describe features — applies to understanding Jurassic Earth geography.

Learning Objectives

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

1. Understand the place of the Jurassic period in Earth’s timeline and identify its chronological order.
2. Describe key characteristics of the Jurassic period including climate, geography, and dominant species.
3. Collaborate to create a visual timeline showcasing the eras of Earth’s history emphasizing the Jurassic period.
4. Evaluate and discuss what life might have been like during this time with reasoned hypotheses.

Resources Required

• Large printed or projected Earth history timeline (from Pre-Cambrian to Quaternary)
• Colourful timeline strips (prepared in advance) for student grouping activity
• Images and fact cards of Jurassic dinosaurs and environment features
• Large chart paper and markers for group work
• Interactive whiteboard or projector
• Sticky notes for student hypotheses
• World map (to locate Jurassic landmasses)

Lesson Structure

1. Starter Activity (10 minutes)

Objective: Activate prior knowledge and introduce the concept of geological time.

• Prompt discussion: “What do you know about dinosaurs and when they lived?”
• Show a simplified timeline of Earth’s history at the front of the classroom.
• Introduce the terms: Mesozoic Era, Triassic, Jurassic, Cretaceous Periods.
• Ask: “Where do you think the Jurassic period fits within this timeline?”

Assessment: Observe verbal responses to gauge existing understanding.

2. Main Teaching Input (15 minutes)

Objective: Develop understanding of Jurassic period characteristics.

• Teacher-led explanation about the Jurassic Period (~201 to 145 million years ago):
  • Warm climate with no polar ice caps.
  • Dominant vegetation: coniferous forests, cycads, and ferns.
  • Notable dinosaurs: Stegosaurus, Allosaurus, Brachiosaurus.
  • Geography: Pangaea beginning to break apart, formation of shallow seas.
• Use visuals: images and video clips (2-3 mins max) to illustrate environment and creatures.
• Locate Jurassic landmasses on the world map to illustrate shifting continents.

Assessment: Questioning throughout to check comprehension and recall.

3. Activity: Group Timeline Creation (20 minutes)

Objective: Construct a detailed visual timeline to reinforce sequencing and facts about the Jurassic period.

• Split 30 students into 5 groups (6 per group). Each group receives timeline strips representing different periods (Pre-Cambrian, Paleozoic, Triassic, Jurassic, Cretaceous, Quaternary).
• Groups order and stick strips onto large chart paper.
• Each group adds key facts and pictures about their assigned period, focusing particularly on Jurassic (they use fact cards).
• Encourage creativity: colours, drawings, quick dinosaur sketches, or significant climate notes.

Assessment: Evaluate group's timelines for accuracy, detail, and participation.

---

4. Class Discussion: Life in the Jurassic (10 minutes)

Objective: Develop hypotheses and reasoning about daily life during the Jurassic period.

• Groups share ideas on “What might life have been like during the Jurassic?”
• Students write their best guess on sticky notes (e.g., diet of dinosaurs, weather, dangers).
• Teacher facilitates to challenge assumptions gently and steer towards scientific evidence.

Assessment: Use of sticky notes to check student reasoning; verbal peer feedback.

---

5. Plenary (5 minutes)

• Recap key points: Where Jurassic sits in Earth’s history, main features of the period.
• Pose a question for reflection: “Why is it important to learn about times like the Jurassic Period?”
• Highlight upcoming lessons: Evolution of dinosaurs, extinction events, fossil evidence.

---

Differentiation

• Support: Pre-prepared vocabulary cards, sentence starters for timelines and discussion.
• Challenge: Encourage some groups to research one Jurassic dinosaur in more detail and present a “Did you know?” fact to the class.
• Use visuals and hands-on activities to engage different learning styles.

---

Assessment Opportunities

• Informal questioning during starter and input phases.
• Observation and evaluation of group timeline activity for understanding of sequencing and content.
• Review of hypotheses during discussion to assess conceptual grasp.
• Sticky note reflections provide a quick written formative assessment.

---

Cross-Curricular Links & Extension Ideas

• English: Write a diary entry from the perspective of a Jurassic animal (to use in language lesson).
• Art: Create 3D dinosaur sculptures using clay or recycled materials in a later lesson.
• Computing: Use digital timeline software for students to create an interactive timeline.

This engaging and interactive introduction to the Jurassic period equips students with a solid chronological framework, knowledge of the period’s environment and organisms, and critical thinking skills aligned with the Key Stage 2 National Curriculum.
