Frequently Asked Questions
Why do we not see stars during the day?
We cannot see stars during the day because the bright light of the sun is too strong and hides the faint light of distant stars.
Does the moon change its shape every day?
No, the moon itself does not change shape. Only the part of the moon lit by the sun that we can see from Earth changes, which creates the phases of the moon.
Why is the sun important for us?
The sun is important because it gives us light to see, warmth to keep us alive, and helps plants grow by providing energy for food.
