Shadows during lunar eclipses are like when the Earth blocks the Sun’s light from reaching the Moon, just like when you stand between a lamp and your friend, blocking their view.
The Moon is like your friend, the Sun is like the lamp, and the Earth is like you. When the Earth comes between them, it stops most of the sunlight from getting to the Moon, making it look darker, this is called a shadow.
What Causes the Shadow
During a lunar eclipse, the Earth moves directly in front of the Sun, casting its shadow on the Moon. The Earth's shadow has two parts: one that’s darker and one that’s lighter. Think of it like when you put your hand between the lamp and your friend, some light still gets through, but not all.
Why It Looks Cool
Sometimes the Moon doesn’t go completely dark, it glows with a reddish color. That’s because some sunlight still bends around the Earth, like how light can bend around the edge of a cup when you look at something behind it. This is why people say the Moon looks like it's wearing a red sweater during an eclipse!
It’s not magic, just light and shadows playing hide-and-seek!
Examples
- A student learns that shadows can look different depending on what's casting them.
- During a family picnic, someone points out the Moon is glowing red instead of disappearing.
