   Table (model data), Model data: Moon dates

   Date	Phase and Moon near Earth's orbit plane?
   A. February new moon	Moon near the plane of Earth's orbit: no

   B. April full moon: yes. C. June full moon: no. D. October new moon: yes.

2. 1.

   Esme studies the example table of four Moon dates. Which date could have a lunar eclipse?

   • D: the October new moon
   • A: the February new moon
   • B: the April full moon
   • C: the June full moon
3. 2.

   Using the same example table, Jun looks for a date that could have a solar eclipse. Which date fits?

   • D: the October new moon
   • B: the April full moon
   • C: the June full moon
   • A: the February new moon
4. 3.

   Side view, not to scale; with the shadow not yet drawn. Luz's friend says a solar eclipse happens when Earth's shadow falls on the Sun. Which response is best?

   • Agree: and it happens at each new moon
   • Disagree: the Moon's shadow falls on Earth
   • Agree: Earth's shadow darkens the Sun
   • Disagree: it happens at full moon, when the Moon is bright
5. 4.

   Milo's cousin says a lunar eclipse is just the Moon's new moon phase. Which response is best?

   • Agree: the Moon's shadow covers the Moon then
   • Disagree: it is seen from just a narrow path
   • Agree: the new moon is Earth's shadow on the Moon
   • Disagree: it happens at full moon, in Earth's shadow
6. 5.

   “not to scale” A post claims that everyone on Earth's daytime side sees each total solar eclipse. Noah checks it. Which response is best?

   • Agree: Earth's shadow covers the whole Sun
   • Agree: the Moon's shadow covers the whole day side
   • Disagree: totality is seen only along a narrow path
   • Disagree: the Moon is as big as the Sun, so the path is wide
7. 6.

   Sun diameter about 1,391,400 km; Moon diameter about 3,475 km. Pia reads the NASA size table. About how many times wider is the Sun than the Moon?

   • About the same width
   • About 4 times wider
   • About 40 times wider
   • About 400 times wider

8. Sizes and distances (NASA)

   Body	Diameter and Distance from Earth
   Sun diameter about 1,391,400 km	distance from Earth about 149,600,000 km
   Moon diameter about 3,475 km	distance from Earth about 384,400 km

9. 7.

   The Sun is about 400 times wider than the Moon and about 389 times farther from Earth. What does Ren explain with these two numbers?

   • Why each new moon makes an eclipse
   • Why the Moon is really as big as the Sun
   • Why they look about the same size in our sky
   • Why Earth's shadow covers the Sun
10. 8.

    “Two side views, not to scale:” When the Moon is at its farthest from Earth, it looks a little smaller. Which eclipse can Tala read about at a new moon then?

    • An annular eclipse, with a ring of Sun showing
    • A lunar eclipse, since the Moon is far away
    • An eclipse at each new moon that season
    • A total eclipse, since the Moon is as big as the Sun
11. 9.

    “Classroom model, top view:” In a class model, a lamp is the Sun, a foam ball is the Moon and Zee's head is Earth. Where should Zee hold the ball to model a lunar eclipse?

    • At Y-high, just above the head's shadow
    • At X, beside the head
    • At W, between the head and the lamp
    • At Y, inside the head's shadow
12. 10.

    In the model, the ball's shadow on Bo's face is a small spot, not the whole face. What does this show about solar eclipses?

    • A small area of Earth sees totality
    • The ball must be as big as the lamp to work
    • The whole day side sees totality at once
    • The head's shadow is what makes a solar eclipse
