how to make solar and lunar eclipse working model for science exhibition with detailed explanation

Creating a solar and lunar eclipse working model using a big ball for the Earth, a thermocol ball for the Moon rotating around the Earth using a slow-running motor, and a big LED bulb for the Sun can be an engaging and educational project.

Here’s how you can do it:

Materials Needed:

  1. Big ball (for Earth)
  2. Thermocol ball (for Moon)
  3. Slow-running motor with attachment
  4. Big LED bulb (for Sun)
  5. Cardboard or foam board
  6. Paints or markers
  7. Color paper
  8. Glue or adhesive
  9. Scissors
  10. Power source (batteries or adapter)
  11. Small round object (for Moon’s shadow)
  12. Toothpick or thin stick

Step by Step Video Instructions on solar and lunar eclipse:

  1. Prepare the Earth:
    • Use the big ball as the Earth model. Paint it blue and green to represent land and water.
    • Place the Earth on a sturdy base.
  2. Create the Moon:
    • Use the thermocol ball as the Moon model. Paint it gray or silver.
    • Attach a small round object (representing the Earth’s shadow during a lunar eclipse) on a toothpick or stick and place it near the Moon.
  3. Attach Moon to Motor:
    • Attach the slow-running motor to the back of the Moon using adhesive.
    • Ensure that the motor is aligned properly so that when it rotates, the Moon orbits around the Earth.
  4. Create the Sun:
    • Use the big LED bulb as the Sun model. Paint it yellow or orange.
    • Decorate the LED bulb with color paper or markers to represent sunspots or solar flares.
  5. Set Up the Model:
    • Place the Sun model on one side, slightly above the Earth model.
    • Attach the Moon model to the slow-running motor, ensuring that it rotates around the Earth.
    • Position the Moon’s shadow object so that it casts a shadow on the Moon during a lunar eclipse.
  6. Test the Model:
    • Connect the motor to a power source (batteries or adapter) and turn it on.
    • Observe how the Moon orbits around the Earth, causing different phases of the Moon.
    • Move the Moon closer to the Earth to simulate a lunar eclipse, and observe how the Earth’s shadow falls on the Moon.
    • Move the Earth between the Sun and the Moon to simulate a solar eclipse, and observe how the Moon’s shadow falls on the Earth.
  7. Explain the Phenomena:
    • Use the model to explain the concepts of solar and lunar eclipses, including how they occur and why they look different from Earth.
    • Demonstrate how the alignment of the Earth, Moon, and Sun causes eclipses to occur.

This working model provides a visual representation of solar and lunar eclipses and helps understand the celestial phenomena in a hands-on way.
