Materials & Equipment

Lesson 1: Introduction: cenozoic era & ice ages

Duration: 50 minutes

Starter Activity (5 minutes)

Quick Recall

Write down everything you already know about cenozoic era & ice ages. Then check against the key terms: key terms from cenozoic era & ice ages. Use a mini-whiteboard or paper.

Main Content (35 minutes)

Parent/Teacher Guide:
Before lesson: Read the script below. Pre-teach key vocab: key terms from cenozoic era & ice ages.
If stuck: Re-read the revision notes (link above), then break the content into smaller steps.
Extension: See the Stretch & Challenge ideas in Lesson 4.
Teaching Script (35 mins):
Mins 0-5 - Hook: "Today: cenozoic era & ice ages. By the end you will be able to answer exam questions on it unaided. It connects to the rest of Geology because the ideas here recur across the spec."
Mins 5-20 - Direct Instruction: Work through the core ideas below one at a time; after each, ask your student to explain it back in their own words.
Mins 20-30 - Guided Practice: Model the worked example together, then let your student attempt the first practice question with guidance.
Mins 30-35 - Independent Practice: 2-3 practice questions from Lesson 3 below, with immediate feedback.
First Look

Start with the revision notes summary, then attempt: explain the key ideas of cenozoic era & ice ages

Plenary (5 minutes)

Check Out

Your student states one thing they learned and one question they still have about cenozoic era & ice ages.

Lesson 2: Core Concepts: cenozoic era & ice ages

Duration: 50 minutes

Starter Activity (5 minutes)

Review Previous Lesson

Quick recap: write 3 key points from Lesson 1 on cenozoic era & ice ages. Check them against the notes below.

Main Content (35 minutes)

Key Fact: The Cenozoic Era (66 Ma to present) is the 'Age of Mammals' — mammals diversified after the dinosaurs went extinct
Key Fact: The Quaternary Period (2.6 Ma to present) includes the Pleistocene (repeated glaciations) and the Holocene (last 11,700 years, current interglacial)
Key Fact: During the Pleistocene, there were multiple glacial (cold) and interglacial (warm) cycles driven by Milankovitch orbital variations
Key Fact: The last glacial maximum was ~20,000 years ago; ice sheets covered much of Britain down to the Midlands
Key Fact: Glaciation shaped the British landscape: U-shaped valleys, corries, drumlins, erratics, till deposits and moraines
Key Fact: Sea level fell ~120 m during glaciations (water stored in ice sheets) and rose again during interglacials, separating Britain from the continent

Practice (10 minutes)

Q: explain the key ideas of cenozoic era & ice ages

Answer:

Plenary (5 minutes)

Explain Back

Your student teaches the key points back to you without looking. Fill any gaps immediately.

Lesson 3: Application: cenozoic era & ice ages

Duration: 50 minutes

Starter Activity (5 minutes)

Quick Recall

Recall the key terms: key terms from cenozoic era & ice ages. Define each in one sentence.

Main Content (35 minutes)

Parent/Teacher Guide: Let your student attempt each question alone first, then compare with the model answer. Award method marks for correct working even if the final answer is wrong.

Work through the practice questions on the revision notes page for this topic.

Plenary (5 minutes)

Error Review

Review any questions answered incorrectly. Identify whether the error was knowledge, method, or reading the question.

Lesson 4: Exam Practice: cenozoic era & ice ages

Duration: 50 minutes

Starter Activity (5 minutes)

Command Words

Review what these command words require: state (one point), describe (say what happens), explain (say why), compare (both sides), evaluate (judgement).

Main Content (35 minutes)

Exam-Style Question

Attempt a past-paper style question on cenozoic era & ice ages from the exam board past paper finder (see Resources), then mark it against the scheme.

Exam Tips: Cenozoic = Age of Mammals (after dinosaurs died out at K-Pg boundary) | Pleistocene = repeated glaciations; Holocene = current warm period | Milankovitch cycles drive glacial-interglacial cycles | British landscape: U-valleys, drumlins, erratics, till all indicate glaciation
Common Errors: ✗ There was only one ice age ✓ There were multiple glacial-interglacial cycles during the Pleistocene; the 'ice age' was a series of cold and warm periods, not a single cold spell ✗ Britain was entirely covered by ice during the last glaciation ✓ Ice covered Britain roughly from the Midlands northward; southern England remained unglaciated but had periglacial conditions (permafrost, freeze-thaw) ✗ Sea level rise during interglacials was caused by thermal expansion alone ✓ Sea level rose mainly because water stored in continental ice sheets returned to the oceans; thermal expansion of seawater was a secondary contribution
Stretch & Challenge (Grade 8-9):
  • Synoptic links: explain how cenozoic era & ice ages connects to another Geology topic you have studied
  • Real-world: research one real-world use or example of cenozoic era & ice ages
  • Critical: "What are the limitations of the models used in cenozoic era & ice ages?"

Assessment Criteria
