Lesson: Earth and Space

Year: 5 | Subject: Science | Time Allocation: 100% (approx. 60-70 minutes)

Class/Set: ____________ Date/Term: ____________

LO (WALT): To describe the movement of the Earth and other planets relative to the Sun, and explain the mechanisms of day, night, and tides.

Success Criteria (WILF):

1. I can describe how the Earth and other planets orbit the Sun.
2. I can explain how the Earth's rotation on its axis creates day and night.
3. I can identify the Moon's gravitational pull as the primary cause of oceanic tides.

1. Starter (15%)

• Facilitate: 'Gravity Brainstorm' retrieval practice. Ask students to spend 2 minutes listing everything they know about gravity and the solar system from Year 3 and 4.
• Question: Use a 'Think-Pair-Share' approach: "If the Sun is so much larger than the Earth, why doesn't the Earth just fall into it?"
• Explain: Introduce the concept of 'orbit' as a balance between the Earth's forward motion and the Sun's gravitational pull.
• Challenge: Ask for a volunteer to name the eight planets in order from the Sun (My Very Easy Method Just Speeds Up Naming).

2. Main Activity (70%)

Teacher Input:

• Explain: Use a large globe and a powerful torch (to represent the Sun). Darken the room if possible to heighten the visual impact.
• Script: "Class, imagine this torch is the Sun. It stays still while the Earth does two things at once. It orbits the Sun—a journey that takes 365 and a quarter days—but it also rotates on its own axis. This axis isn't straight up and down; it's tilted. As the Earth spins, the side facing the Sun experiences day, while the side facing away experiences night."
• Model: Rotate the globe slowly. Point to the UK on the globe. Demonstrate: "Look at the UK now. It’s in the light. As I spin the globe, watch how it moves into the shadow. This is what we see as sunset."
• Explain: Transition to the Moon and Tides. Model: Place a smaller ball (the Moon) near the globe. Script: "The Moon doesn't just look pretty; it’s a powerful magnet for our oceans. Its gravity pulls on the Earth’s water, creating a 'bulge'. As the Earth spins through these bulges, we experience high tide and low tide."
• Check: Ask a student to explain why we have two high tides a day if the Moon is only on one side. (Clarify the concept of the 'centrifugal' bulge on the opposite side).

Student Task:

• Task A (Orbits): Draw a scientific diagram of the solar system. Label: Include the Sun, Earth, Moon, and at least three other planets. Annotate: Use arrows to show the direction of orbits and rotation.
• Task B (Day & Night): Write a 'Letter to a Penpal' in Australia. Explain: Describe why, when it is 10:00 am and sunny in London, it is 8:00 pm and dark in Sydney. Use the terms 'axis', 'rotation', and 'spherical'.
• Task C (Tides Reasoning): Analyse a tide timetable for a local coastal town (e.g., Blackpool or Brighton).
  • a) ☐ Identify the time of the highest tide.
  • b) ☐ Identify the time of the lowest tide.
  • c) ☐ Explain what would happen to the tides if the Moon were twice as far away from Earth.
• Support: Provide a 'Word Bank' for Task B (Axis, Rotation, Orbit, Celestial, Hemisphere).

3. Plenary (15%)

• Evaluate: Conduct a 'Human Solar System' demonstration. Assign students roles (Sun, Earth, Moon). Have them move physically to represent a day, a month, and a year.
• Check: 'Hinge Question' via MCQ (Multiple Choice Question):
  • What is the primary cause of tides on Earth?
  • a) ☐ The wind blowing across the Atlantic Ocean.
  • b) ☐ The gravitational pull of the Moon.
  • c) ☐ The Earth's orbit around the Sun.
  • d) ☐ Underwater volcanoes.
• Consolidate: Review the 'Success Criteria'. Have students tick off which ones they feel confident about in their exercise books.

4. Resources

• Large globe and high-intensity torch.
• Small sphere (Moon model).
• Exercise books and coloured pencils.
• Tide timetable handouts (localised data).
• 'Word Bank' scaffolds for EAL/SEND students.

⚠ TEACHER’S GUIDANCE

🚀 Pedagogical Landing

• Year 5 Calibration: At this stage, students often confuse 'rotation' (spinning on an axis) with 'revolution/orbit' (circling the Sun). Ensure you use physical modelling to distinguish these two movements clearly.
• Misconception Alert: Many students believe the Sun 'moves' across the sky. Explicitly use the globe and torch to show that it is the Earth's movement that creates this illusion.
• Working Scientifically: Encourage students to use the tide timetable to look for patterns. This builds 'Data Interpretation' skills required at KS2.
• Safety & Nuance Check: ⚠ Ensure students do not look directly into the high-intensity torch during the demonstration to protect their eyesight.

✅ Answer Key & Mark Scheme

• Task A (Orbits):

  • Sun: Central position.
  • Earth/Moon: Moon orbiting Earth while Earth orbits Sun.
  • Planets: Correct relative order (Mercury, Venus, Earth, Mars, etc.).
  • Arrows: Anti-clockwise direction is scientifically accurate for most orbits.

• Task B (Day & Night):

  • Explanation: Must state that the Earth is a sphere and rotates on its axis.
  • Reasoning: Because the UK and Australia are in different positions (hemispheres/longitudes), they face the Sun at different times.

• Task C (Tides Reasoning):

  • Task C Answer (a & b): (Dependent on the specific timetable provided in class).
  • Task C Answer (c): If the Moon were further away, its gravitational pull would be weaker. Therefore, the tidal bulge would be smaller, and the difference between high and low tide would decrease.

• Plenary Hinge Question Answer:

  • b) ☐ The gravitational pull of the Moon.
