Week 1: Movement and Light Waves
Unit Overview
This week introduces students to the fundamental movements of objects in space: rotation (spinning) and revolution (orbiting). We also explore how light travels and how it helps us see the Moon.
Daily breakdown
Day 1: Spinning Earth.
Introduction to rotation and day/night. Activity: Spinning like a top.
Day 2: The Big Circle.
Introduction to revolution (orbit). How long does one year take?
Day 3: Moon Phases Lab.
Hands-on cookie lab to visualize moon phases (see Cookie Moon Lab).
Day 4: Light Waves.
How light reflects off the moon. Waves are like hills and valleys.
Day 5: Review & Quiz.
Review with vocab cards and complete the weekly mastery check.
Key Concepts
Rotation: Earth spins every 24 hours.Revolution: Earth orbits the Sun every 365 days.Phases: How the moon looks from Earth.Waves: How light moves through space.
Teaching Tip
Use a flashlight and a globe to show how rotation creates day and night. Students often confuse rotation with revolution!

Mission Instructions
Choose one student to be the Sun in the middle.
Choose one student to be the Earth.
The Earth student must rotate (spin) slowly in a circle.
While spinning, the Earth student must revolve (walk) around the Sun.
Observation Notes
1. What happened to the Earth's view as it spun around (rotated)?
2. How many times did you spin (rotate) before you made one full circle (orbit) around the Sun?
Did You Know?
Earth rotates very fast—over 1,000 miles per hour! But it is so huge that we don't feel the spinning at all.

Week 1: Movement & Light
Rotation
To rotate means to spin in one spot.
The Earth rotates like a top. This makes day and night!
One spin = 24 Hours
Revolution
One orbit = 1 Year
To revolve means to go around the Sun.
This path is called an orbit. It takes 365 days to finish!
The Moon's Dance
Mirror Light
The Moon does not make its own light. It reflects the Sun!
Orbiting Earth
The Moon revolves around the Earth once a month.
Changing Phases
Because it moves, we see different amounts of its lit side.
Waves of Light
Light travels in waves. In space, light waves travel very fast until they hit something.
We see planets because light waves from the Sun bounce off them!

The Earth is always moving. Even when you are sleeping, our planet is busy! It moves in two special ways.
1. The Big Spin
First, the Earth spins. This is called rotation . It takes 24 hours to spin one time. When your side of Earth faces the Sun, it is day. When you spin away from the Sun, it is night.
2. The Big Circle
Second, the Earth goes around the Sun. This is called revolution . Earth follows a path called an orbit . It takes one whole year to go around the Sun.
The Moon is busy, too! It revolves around the Earth. The Moon does not have its own light. It is like a mirror. It reflects light from the Sun. As the Moon moves, it looks like it changes shape. These shapes are called phases .
How do we see the planets? We use our eyes to catch light waves . Light waves from the Sun hit the planets and bounce back to us. That is why the night sky looks so bright and beautiful!
Mission Check-Up
Show what you learned about Earth's movement!
1 What is it called when the Earth spins in one spot?
A) Revolution
