# data[].attributes.wish_content.attachment_props.question
The Earth is directly between the Sun and the Moon, casting a shadow on the Moon. Which event is occurring?

# data[].attributes.body
Time: 2 minutes

Task:

Think about what you already know about eclipses.

Write 2 sentences explaining why eclipses do not happen every month.

Peer Interaction:

Reply to ONE classmate with agree or disagree and provide reasoning.

# data[].attributes.body
Solar Eclipse: Sun → Moon → Earth. Moon blocks sunlight for part of Earth.
Lunar Eclipse: Sun → Earth → Moon. Earth blocks sunlight from reaching Moon.

Shadows:

Umbra = full shadow

Penumbra = partial shadow

Chat Questions:

1. Which eclipse involves Earth's shadow?

2. Which eclipse is dangerous to look at?

Look at the diagram shared by the teacher.

Answer in chat:

1. Solar or lunar eclipse?

2. Object in the middle?

3. Location of the shadow?

Challenge: Why doesn’t this happen every month?
