Creating an Earth gravitation working model using two balls (representing Earth and the Moon), magnets, and threads is a creative way to demonstrate the concept of gravitational attraction. Here’s a step-by-step guide to help you build this science project:

### Materials Needed

• Two balls (one larger for Earth and one smaller for the Moon)
• Magnets (small, strong magnets)
• Threads (fishing line or thin string)
• Cardboard or sturdy base
• Glue or tape
• Scissors
• Marker
• Optional: Decorative materials (paint, markers, etc.)

### Tools Needed

• Screwdriver (if needed to handle magnets)
• Hot glue gun (if needed for stronger attachment)

## Step by Step Guide to Make the earth gravitation working model

#### 1. Prepare the Base and Setup

1. Base Setup:
• Cut a piece of cardboard or use a sturdy base as the foundation for your model.
• Decorate the base to represent space or the solar system, if desired.
2. Positioning Earth and Moon:
• Decide where to place the larger ball (Earth) and the smaller ball (Moon) on the base.
• Leave enough space between them to allow for the threads and magnets.

#### 2. Attach Magnets to Balls

1. Attach Magnets to Earth and Moon:
• Carefully attach small magnets to each ball using hot glue or tape.
• Ensure the magnets are securely attached to the center or near the center of each ball.

• Cut several pieces of thread (fishing line or thin string) of varying lengths.
• Tie one end of each thread securely to the base at different points around the Earth.
• Tie the other ends of the threads to the Moon ball.
• Distribute the threads evenly around the Moon to simulate gravitational attraction from different directions.

#### 4. Demonstrate Gravitational Pull

• Position the Earth and Moon balls on the base so that the threads are taut but not pulling excessively.
2. Interactive Demonstration:
• Show how the Earth ball (larger) exerts a stronger gravitational pull on the Moon ball (smaller) due to its larger size and mass.
• Move the Moon ball around slightly to demonstrate how the threads (gravitational force) keep it in orbit around the Earth.

#### 5. Optional Enhancements and Explanations

1. Decorate and Label:
• Decorate the base or balls to visually represent the Earth and Moon.
• Label the components to explain the model’s parts and their functions.
2. Educational Value:
• Explain gravitational attraction as a force that pulls objects toward each other based on their mass and distance.
• Discuss how the Moon orbits the Earth due to Earth’s gravitational pull.

By following these steps, you’ll create an engaging and educational Earth gravitation working model using balls, magnets, and threads. This project effectively demonstrates the concept of gravitational attraction in a visual and interactive manner, making it ideal for science fairs or classroom demonstrations.
