Concept
This working model demonstrates how solar and lunar eclipses occur using a circular base, with Earth on top, the Moon moving around it, and the Sun positioned next to the base. It helps visualize how the alignment of the Sun, Earth, and Moon creates eclipses.
Materials Required
- Thermocol balls (for Sun, Earth, and Moon)
- Circular base (cardboard or thermocol)
- Sticks or wires (to hold and rotate the Moon)
- Paints & markers (for coloring)
- Glue & tape
Model Setup
- Base Setup:
- Use a circular base to represent the orbital plane.
- Place Earth on top of the base (fixed in the center).
- Attach the Moon to a rotating stick around Earth.
- Place the Sun next to the base.
- Solar Eclipse Demonstration:
- Move the Moon between the Sun and Earth so that it blocks sunlight, creating a shadow on Earth (Total Solar Eclipse).
- Lunar Eclipse Demonstration:
- Move the Earth between the Sun and Moon, so Earth’s shadow falls on the Moon, showing a Lunar Eclipse.
Key Learning Points:
- Solar Eclipse occurs when the Moon blocks sunlight from reaching Earth.
- Lunar Eclipse occurs when Earth’s shadow covers the Moon.
- The Moon’s orbit and alignment determine when eclipses occur.
