Earth’s Rhythms and Motions

Grade 6 Science

Duration: 70 minutes
Class Size: 36 students

Learning Objectives (Aligned to Common Core and NGSS)

Next Generation Science Standards (NGSS)

• MS-ESS1-1: Develop and use a model of the Earth-sun-moon system to describe the cyclic patterns of lunar phases, eclipses of the sun and moon, and seasons.
• MS-ESS1-2: Develop and use a model to describe the role of gravity in the motions within galaxies and the solar system.

Common Core State Standards (CCSS ELA) - Crosscutting with Science

• RI.6.3: Analyze a scientific text to explain how the moon’s and sun’s influence cause tides and seasons.
• SL.6.4: Present information clearly, emphasizing key points about Earth’s tilt, rotation, revolution, tides, and seasons.

---

I Can... Statements

• I can explain how Earth’s rotation and revolution cause day/night and seasons.
• I can describe how the tilt of the Earth influences seasons and equinoxes.
• I can explain how the gravitational pull of the moon and sun causes tides.

---

Success Criteria

• Illustrate Earth’s rotation and revolution in a diagram showing day/night and seasons.
• Use models to show how tides are created by gravitational forces.
• Accurately define equinox and solstice and their significance.
• Work in groups to demonstrate understanding and present clear explanations.

---

Materials Needed

• Globe for Earth model
• Flashlight (representing the Sun)
• Ball (representing the Moon)
• Large poster paper and markers
• Tide chart printouts
• Lined paper and pencils
• Projector for short animations/videos (optional)

Lesson Breakdown

1. Engage & Explore: Earth’s Movements (10 minutes)

• Activity: Using a globe and flashlight, demonstrate Earth’s rotation (24 hours) and revolution (365 days).
• Discussion: Ask students why we have day and night, introduce the concept of tilt (23.5 degrees).
• Differentiation:
  • Visual learners benefit from the physical globe and light.
  • Provide sentence starters for ELL or struggling writers: "Earth spins to make ________."
• Formative Check: Ask students to turn & talk: What would happen if Earth didn’t tilt?

---

2. Explain: Seasons and Equinoxes (15 minutes)

• Use the globe to model Earth’s tilt and orbit around the sun.
• Define equinox (equal day/night) and solstice (longest/shortest day).
• Students sketch quick diagrams of Earth’s position during each season.
• I Can Focus: I can describe how Earth’s tilt causes seasons and equinoxes.
• Success Criteria: Accurate diagram labeling and correct explanation.
• Differentiation:
  • Provide fill-in-the-blank diagrams for struggling learners.
  • Advanced learners: Research how seasons differ in the Southern Hemisphere.

---

3. Explore: Tides and the Moon’s Influence (20 minutes)

• Hands-on Model: Pair students — one holds a ball (moon), one globe (Earth). Using string or their arms to demonstrate the gravitational pull causing ocean tides.
• Show tide charts, discuss how sun and moon influence daily tides (high vs low).
• I Can Focus: I can explain how the moon and sun cause tides.
• Success Criteria: Demonstrating the tide model and describing tidal patterns.
• Differentiation:
  • Use peer support for hands-on modeling
  • Provide visual tidal graphs and key vocabulary list (gravity, tide, moon phase).
  • Extension: Calculate tidal differences in two different locations using provided data.

---

4. Explain & Apply: Rotation, Revolution, and Daily Patterns (10 minutes)

• Review rotation (day/night) and revolution (year cycle) with students summarizing in their own words.
• Use a short animation or diagram to reinforce concepts.
• Mini quiz/discussion: What would Earth be like without rotation? Without revolution?
• I Can Focus: I can summarize Earth’s movements and their effects.
• Success Criteria: Participation in quiz and accurately stating effects.

---

5. Group Challenge: Design a Tides and Seasons Comic Strip (15 minutes)

• Students create a 4-panel comic strip explaining tides, Earth’s tilt, and seasons using simple drawings and words.
• Groups present strips to the class (2 minutes each).
• Differentiation:
  • Provide templates with example panels for those who need more support.
  • Encourage advanced learners to include scientific terms and extra detail.

---

Assessment

• Observation of student participation during models and discussions.
• Review comic strips for accurate scientific understanding.
• Exit ticket: Write a 2-3 sentence response to "How do Earth’s tilt and the moon’s gravity make life on Earth different every day?"

---

Extension Activities for Advanced Learners

• Research and present how tides differ on the coasts of the U.S. (Pacific vs Atlantic).
• Investigate the science behind eclipses related to Earth, Moon, and Sun positions.
• Write a short story imagining a day on a planet with no tilt or different rotation speed.

---

Additional Differentiation Strategies

• For students with special needs: Incorporate tactile models and visuals; allow oral or video responses.
• For ELL students: Provide vocabulary flashcards ahead of time; pair with bilingual peers; use gestures and visual aids.
• For students with high interest: Challenge them to create a digital animation or video explaining the concepts.
