Lesson Procedure

3 mins - Welcome Time

• Sing the "Hello Song"

• Introduce today's topic: "Today we're going to learn about Earth's Big Journey around the Sun!"

7 mins - Discovery Chat

• Show a globe and a large yellow ball (representing the Sun)

• Explain: "Earth moves in two ways. It spins like a top (demonstrate), and it also moves around the Sun (demonstrate)."

• Discuss: "It takes one year for Earth to go all the way around the Sun. This journey gives us our seasons."

10 mins - Hands-On Challenge 1: Earth's Movement

• Choose one child to be the "Sun" (holding a yellow ball or flashlight)

• Another child is "Earth" (holding a globe)

• Guide "Earth" to spin slowly (rotation) and move around "Sun" (revolution)

• Other children form a big circle around "Sun" to represent Earth's orbit

• As "Earth" moves, explain how this creates seasons

• Let children take turns being Sun and Earth

10 mins - Hands-On Challenge 2: Seasons in Hong Kong

• Use a globe to find and mark Hong Kong

• Demonstrate Earth's position for each season using the globe and "Sun"

• Discuss characteristics of each season in Hong Kong:

  - Spring: Warm, flowers bloom
  - Summer: Hot and humid
  - Autumn: Cooler, leaves change color
  - Winter: Coolest season

• Ask children to act out activities for each season (e.g., planting flowers in spring, swimming in summer)

12 mins - Hands-On Challenge 3: Dress Serena for the Seasons

• Divide children into small groups

• Give each group a paper doll named Serena and various paper clothes

• One child acts as the Sun, another moves the globe around the Sun

• As Earth moves, call out different seasons

• Groups quickly dress Serena in appropriate clothes for each season

• Discuss choices: "Why did you choose that jacket for winter?"

3 mins - Wrap-Up

• Recap: "Today we learned about all the planets in our solar system. We colored them and put them in order from the sun!"
