What Is an Eclipse? 🌒

Sometimes the sky does something amazing in the daytime — or paints the Moon red at night!

An eclipse happens when the Sun, the Moon, and the Earth line up in a special way — so one casts a shadow on another.

☀️ Sun

A giant ball of fire that makes its own light.

🌍 Earth

Our home! It does not make light — it borrows the Sun's.

🌕 Moon

Earth's rocky neighbour. It moves around the Earth.

An eclipse is really just a shadow. When something blocks the light, it makes a dark shadow behind it. Try it!

When light is blocked, where does the shadow fall?

In space, the Sun is the light, and the Moon or Earth can be the blocker!

Drag the Moon up or down until it slides right in front of the Sun. Then it blocks the sunlight from reaching part of the Earth — day turns dark!

Slide the Moon into the line between the Sun and the Earth.

At night, the Earth can get in the way and throw its shadow onto the Moon. The Moon turns a spooky red — people call it a Blood Moon!

What colour will the Moon turn?

A solar eclipse is exciting — but the Sun's light can hurt your eyes badly. Which is the SAFE way to watch one?

Pick the one that protects your eyes.

⚠️ Real rule: Never look straight at the Sun, even during an eclipse, without special eclipse glasses.

Read each clue. Is it a Solar eclipse (Moon blocks Sun) or a Lunar eclipse (Earth's shadow on Moon)?

Brilliant work! Here is everything you discovered:

An eclipse is just a shadow in space when the Sun, Moon and Earth line up.
Solar eclipse: the Moon blocks the Sun, so daytime goes dark for a moment.
Lunar eclipse: the Earth's shadow falls on the Moon, turning it red — a Blood Moon!
Safety: never look straight at the Sun — use special eclipse glasses.

🌟 Next time an eclipse comes to Singapore, you'll know exactly what's happening in the sky. Well done, star-watcher!
