Sally wants to design a model that will show how the Earth-Sun-Moon system causes the Moon’s phases. She has a lamp, a tennis ball, and a cotton ball. Sally decides to set the lit lamp on a table to represent the Sun. How can Sally use the tennis ball and cotton ball to represent the new moon phase?
She can place the tennis ball, representing Earth, and the cotton ball, representing the Moon, on opposite sides of the lamp.
She can hold the tennis ball, representing the Moon, and the cotton ball, representing Earth, in the same hand and move them in a circle around the lamp.
She can hold the tennis ball, representing Earth, in one hand within the lamp’s light and hold the cotton ball, representing the Moon, in her other hand between the lamp and the tennis ball.
She can hold the tennis ball, representing the Moon, in her right hand and the cotton ball, representing Earth, in her left hand within the lamp’s light. Then she can have someone else turn the lamp on and off repeatedly.

solar eclipse
new moon
lunar eclipse
astral eclipse
The longest a total solar eclipse lasts is about how long?
1 minute
7 minutes
30 minutes

Why don’t solar eclipses occur every new moon?
The Moon's orbit around Earth and Earth's orbit around the Sun are not the same speed, so the three bodies only line up during the full moon.
The Moon’s orbit around Earth and Earth’s orbit around the Sun are not in the same plane, so the three bodies only line up occasionally.
The Moon’s orbit around the Sun and Earth’s orbit around the Sun are not in the same plane, so the three bodies only line up occasionally.
The Moon’s orbit around Earth and the Sun’s orbit around Earth are not in the same plane, so the three bodies only line up occasionally.

Which describes a characteristic that is shared by different galaxies in the universe?
They all are about the same distance from the Milky Way.

Objects in orbit are in motion, and are not affected by gravity.
Objects far apart pull on each other more strongly than objects close together.
Objects with a large mass pull with more force than objects with a small mass.

Dan is creating a model of a galaxy. The first part of the model is the drawing shown. Which additions to Dan’s model will correctly show both gravitational force and its effect within the galaxy?

a straight arrow pointing inward from one galaxy arm toward the center of the galaxy, and straight arrows showing the galaxy’s path through space
straight arrows pointing outward and inward from the center of the galaxy, and curved arrows showing the rotation of objects around the center of the galaxy
straight arrows pointing inward from outside each of the galaxy’s arms, and straight arrows showing the paths of objects moving from within to outside the galaxy
James has created the diagram shown to model three planets in the order of their gravitational force with the Sun. Which change to the model will make it more accurate and why?
reorder the planets to Mercury, Earth, Jupiter, because both distance from the Sun and the planets’ masses influence gravitational pull
reorder the planets to Mercury, Earth, Jupiter, because the Sun pulls more strongly on smaller planets than on larger planets
keep the same order but move Earth and Mercury much farther away, because gravitational pull increases as distance from the Sun increases
put all three planets the same distance from the Sun, because the Sun’s constant mass causes the same gravitational pull on all three planets
