The big idea
A solar eclipse occurs when the Moon passes between Earth and the Sun and its shadow reaches part of Earth.
Eclipses are rare at any location because the Moon's orbit is tilted and its shadow covers a narrow path.
◉
HOW SCIENTISTS KNOW
Orbital geometry predicts eclipse paths and timing to great accuracy.

!A COMMON WRONG MODEL
A solar eclipse happens every new Moon.
✓REBUILD IT WITH EVIDENCE
The Moon's tilted orbit usually carries its shadow above or below Earth.
A scientifically true sentence can still create a false picture. This repair makes the relationship visible.
Take learning into real life
Try it together
Never look at the Sun or improvise a solar viewer. Indoors, use a stationary flashlight as the Sun, a small ball as the Moon and a wall as Earth to model a narrow moving shadow.
YELLOW SAFETYAdult setup and supervision are required. Follow the material and eye-safety limits in the activity.
