π Shadows and the Moon
βοΈ How Shadows Are Formed
When light shines on an object and the light cannot pass through, a dark shape appears behind it. This shape is called a shadow.
π¦ Light rays travel in a straight line.
π If something blocks the light, it creates a shadow behind it.
πΆοΈ Shadows Change with the Sun
Shadows are longest in the early morning and late afternoon.
They are shortest at midday when the sun is high in the sky.
In the morning, shadows fall to the west.
In the evening, they fall to the east.
π Changes in the Moon
The moon is a big ball that moves around the Earth.
We can only see the part of the moon that sunlight shines on.
π When the moon is growing bigger, we say it is waxing.
π When it is getting smaller, we say it is waning.
