Objective

By the end of this lesson, the student will understand how the Earth and Sun interact to cause regular changes, such as day and night, seasons, and weather patterns. The student will also learn how these interactions affect the Earth's surface through erosion, sedimentation, and other natural processes.

Materials and Prep

• Paper
• Colored pencils or markers
• A ruler (optional)
• Access to a window or outdoor space

Before the lesson, make sure to find a comfortable space with good lighting. You might also want to check the weather outside to observe any changes during the lesson.

Activities

1. Drawing the Earth-Sun System

   Using paper and colored pencils, draw a picture of the Earth and Sun. Label the Earth’s rotation and revolution around the Sun. Highlight how these movements create day and night and the changing seasons.

2. Shadow Play

   Go outside and observe your shadow at different times of the day. Measure the length of your shadow and discuss how the position of the Sun affects its size. Draw a chart showing the changes in shadow length.

3. Weather Wheel

   Create a simple weather wheel on paper. Divide it into sections for different types of weather (sunny, rainy, cloudy, snowy). Discuss how the Sun influences weather patterns and color in the wheel based on today’s weather.

4. Earth Surface Changes

   Think about how the Earth’s surface changes over time. Draw a before and after picture of a landscape (like a river bank) and explain how water and sunlight can change it.

Talking Points

• "Did you know that the Earth spins like a top? This is why we have day and night!"
• "When the Earth goes around the Sun, it takes a whole year! This is what gives us seasons."
• "The Sun is super important for weather. It warms the air and helps clouds form!"
• "Have you ever noticed how your shadow changes? That's because the Sun moves across the sky!"
• "Erosion happens when wind or water wears away rocks and soil. The Sun helps by making water flow!"
