Solar and lunar eclipses

Grade 6 Science Worksheet

Circle the best answer.

1. Read this first

   Use this

   Side view, not to scale: the Moon's orbit drawn tilted about 5° to the line from the Sun to Earth; at this new moon the Moon passes above the line.

2. 1.

   There is a new moon every month, but Bo learns that solar eclipses are much rarer than that. Why?

   • Each new moon makes one, but many people miss seeing it
   • The Moon's tilted orbit usually misses the line
   • Solar eclipses need a full moon instead
   • The Moon is too small to block the Sun
3. 2.

   Kira reads that a lunar eclipse is coming tonight. Who on Earth will be able to see it, if the sky is clear?

   • Anyone on the night side with the Moon up
   • Just people along a narrow path
   • Just people on the daytime side
   • Just people with a telescope
4. 3.

   Luz reads that the April 2024 total solar eclipse crossed Texas, while New York City saw only part of the Sun covered. Why?

   • The whole day side should have seen totality
   • New York was in Earth's shadow instead
   • Only the Moon's inner shadow brings totality
   • The Moon and Sun are the same size, so only Texas lined up
5. 4.

   The Moon's small dark shadow touching Earth, with an arrow showing the shadow moving across the surface. Milo reads that totality lasts only a few minutes in any one town. Why is a total solar eclipse so short in one place?

   • The Moon changes phase within a few minutes
   • The Moon's small shadow moves fast across Earth
   • Earth's shadow slides off the Moon quickly
   • The eclipse covers the whole day side at once
6. 5.

   “Book drawing (not a view to copy):” Noah reads about an annular eclipse, when a bright ring of Sun stays around the dark Moon. Why doesn't the Moon cover the whole Sun?

   • The Moon is the same size as the Sun, so edges show
   • It is a full moon, which looks smaller
   • Earth sits in the middle and blocks part of it
   • The Moon is farther away then, so it looks smaller

7. Side view, not to scale

   a small circle (the Moon) close to an eye and a huge circle (the Sun) far away, with two lines from the eye touching the edges of both.

8. 6.

   The Moon is far smaller than the Sun, yet Pia reads that it can cover the whole Sun in a total eclipse. How?

   • The Sun shrinks a little at each new moon
   • Earth's shadow also helps cover the rest of the Sun's face
   • The Sun is about 400 times wider and 400 times farther
   • The Moon and Sun are really about the same size
9. 7.

   Ren's diagram shows the Moon's shadow on Earth: place X in the dark inner shadow, Y in the lighter outer shadow, Z outside both. Which place sees part of the Sun covered?

   • Y, in the lighter outer shadow
   • Z, since the eclipse covers the whole day side
   • Y, because Earth's shadow is there
   • X, in the dark inner shadow
10. 8.

    Side view. During a total lunar eclipse, the Moon looks coppery red instead of black. Tala wants to know why. Which answer fits?

    • The Moon glows red by itself once it is in the dark
    • The red is a normal monthly phase
    • The Moon's shadow on Earth turns red
    • Earth's air bends some red sunlight into the shadow
11. 9.

    Two side views, not to scale: the Moon inside Earth's wide shadow; Earth with the Moon's small shadow touching it. Totality in a lunar eclipse can last over an hour, but a total solar eclipse lasts only minutes in one place. Zee asks why. Which answer fits?

    • Lunar eclipses happen at new moon, when nights are long
    • Earth's shadow is much bigger than the Moon's
    • The Moon's shadow is bigger, so it passes slowly
    • A lunar eclipse covers just a narrow path of Earth
12. 10.

    “Side view, not to scale:” In a total lunar eclipse, the whole Moon goes dark red, not just one edge. What does Ari learn from this about the two sizes?

    • Earth's shadow is wide enough to hold the whole Moon
    • The Moon is as wide as Earth, so the shadow just fits it
    • The Moon's shadow covers the Moon
    • It is the new moon phase, with no lit side
