Weekly Lesson Plan: Why Do We Have Day and Night?
Lesson Overview
Target Age: 6 Years Old (1st Grade)
Subject: Earth Science
Duration: 1 Week (5 Daily Sessions, 30-45 minutes each)
Learning Objectives
By the end of this week, the learner will be able to:
- Identify the Sun as a source of light and the Earth as our home.
- Define "rotation" as spinning like a top.
- Demonstrate how the Earth’s rotation creates day and night using a model.
- Explain that while one side of the Earth is in sunlight (Day), the other is in shadow (Night).
Materials Needed
- A globe (or a large ball like a basketball)
- A strong flashlight (to represent the Sun)
- A small sticker (to represent "us" on the map)
- Dark construction paper and yellow construction paper
- Crayons or markers
- A spinning top or a fidget spinner
- "Day and Night" Log (a simple notebook or printed chart)
Day 1: The Great Light in the Sky
The Hook: Ask the student, "Does the Sun go to sleep at night? Where does it go when you go to bed?"
Content & Practice
- I Do: Explain that the Sun is a giant star that is always shining. It doesn't actually "move" across the sky; we are the ones moving!
- We Do: Look at pictures of the Sun and the Earth. Identify where we live on the globe and place a sticker there.
- You Do: Draw a picture of the Sun on one side of a piece of paper and the Earth on the other. Draw a line connecting the light to the Earth.
Talking Point: "Imagine the Sun is a giant, unmoving campfire, and we are walking around it!"
Day 2: The Big Spin (Rotation)
The Hook: Give the student a spinning top or a fidget spinner. Ask, "What do we call it when something turns around and around in one spot?"
Content & Practice
- I Do: Introduce the word Rotation. Explain that the Earth spins around like a top, but it spins very slowly so we don't feel it.
- We Do: Stand up! Have the student stand in one spot and spin slowly. This is "Earth Rotation."
- You Do: Play a game of "Freeze Spin." When you say "Rotate," the student spins. When you say "Orbit," they walk in a circle. Focus on rotation today.
Talking Point: "The Earth is like a giant spinning dancer. It never stops turning!"
Day 3: The Flashlight Experiment
The Hook: Dim the lights. Turn on the flashlight. "If this flashlight is the Sun, why is half of the ball dark?"
Content & Practice (The "Model" Day)
- I Do: Hold the flashlight (Sun) steady. Hold the globe (Earth) in front of it. Show how the light only hits the side facing the flashlight.
- We Do: Find the sticker (where we live). Slowly rotate the globe. Watch the sticker move from the light (Morning), to the center of the light (Noon), to the edge (Sunset), and into the dark (Night).
- You Do: Let the student hold the globe and "make the sun rise" for the sticker by rotating the Earth toward the light.
Success Criteria: The student can point to the "Day" side and the "Night" side of the globe.
Day 4: People on the Other Side
The Hook: "When you are eating breakfast, what do you think children in Australia or China are doing?"
Content & Practice
- I Do: Explain that because the Earth is a sphere (round), it is always daytime somewhere and nighttime somewhere else.
- We Do: Look at the globe. Find a spot exactly opposite of where you live. If it is light on our side, what is it on their side? (Night!)
- You Do: Fold a piece of paper in half. On one side, draw things you do during the day (play, eat). On the other side, draw things you do at night (sleep, look at stars).
Talking Point: "While we are dreaming, friends on the other side of the world are just waking up to play!"
Day 5: Review and Creation
The Hook: "You are now a Science Teacher! Can you show me how Day and Night work?"
Content & Practice
- I Do: Briefly recap the week: Sun stays still, Earth rotates, light vs. shadow.
- We Do: Create a "Day/Night" plate. Take a paper plate, color half black and half blue/yellow. Attach a small paper person that can slide from one side to the other.
- You Do (Summative Assessment): The student uses the globe and flashlight to explain the process of a 24-hour day to a family member or friend.
Assessment Methods
- Formative (During the week): Check if the student can correctly identify the "light" side as Day and "dark" side as Night during the Day 3 experiment.
- Summative (End of week): The "Teach-Back" session where the student demonstrates Earth's rotation using the model and correctly uses the word "Rotate."
Differentiation & Adaptability
- For Kinesthetic Learners: Increase the "Body Earth" activity. Have them wear a shirt with a "Sun" on the front and rotate to see when they "see" the light source in the room.
- For Advanced Learners: Introduce the concept of the Axis (the invisible line Earth spins on) and how it takes 24 hours for one full spin.
- For Struggling Learners: Focus strictly on the "Light vs. Dark" visual. Use a lamp without a shade to make the contrast very sharp.
Success Criteria
The student is successful if they can:
- Say: "The Earth spins."
- Point to the side of the globe facing the light and say "Day."
- Point to the side of the globe in the shadow and say "Night."
