Patterns of Earth and Sky
What is the only star in our Solar System?
The Sun
How many stars are in our solar system?
One
What is the fastest thing in the universe?
Light
In the light video we watched, the lights from the city that made it more difficult to see the stars were measured and referred to as what? Hint: It gave the different levels of each view at the bottom of each screen!
Light Pollution
A group of friends were talking about why the Sun appears larger than other stars in the sky. They compared the appearance of the Sun with that of other stars.
Which situation best models how the Sun appears larger than other stars?
A. People who are close to you have more mass than people further away.
B. Trees that are close to you appear taller than trees that are farther away
C. Houses that are close to you appear smaller than houses that are further away.
D. Mountains that are close to you have a greater volume than mountains that are further away.
B. Trees that are close to you appear taller than trees that are farther away.

What direction does the Earth spin?
Counterclockwise
True or False: No stars are visible during the daytime.
False
The students in Mrs. Green’s class are studying the sun and the stars. Which statement best supports the argument about the size of the sun.
A. The sun is the largest star in the universe because it looks big.
B. The sun looks bigger than the other stars because it is closer to Earth.
C. The Earth is bigger than the sun.
B. The sun looks bigger than the other stars because it is closer to Earth.
This creates day and night and the apparent movement of the sun and stars throughout the day and night
Rotation
Deneb and Altair look the exact same from Earth but Deneb is much further than Altair. What does this tell you about their size?
Deneb is much larger than Altair
How are distances to stars measured?
Lightyears
Why don't we see a lot of stars in the daytime?
Possible answer: The Sun outshines the other stars during the daytime because it is the CLOSEST Star to Earth. It looks brighter than other stars that are further away. We can see more stars at night because at nighttime we are facing away from the Sun.
This movement causes us to see different stars at different times of the year
Revolution
Collection of planets that orbit the sun
Solar System
What is one pattern that we have observed during the course of the unit?
Day and night, how the stars move during the night, Earth's movement around the sun, how the stars move throughout the year, etc.
Why do we see different stars at different time of the year?
Possible Answer: We see different stars/ constellations throughout the year because the Earth ORBITS or REVOLVES around the Sun once a year. The Earth is in different positions/locations around the Sun and at nighttime we face different stars. The stars do not move, the Earth revolves/orbits around the sun.
Earth's gravity pulls us in which direction
To the center of the Earth
Michael states that the stars change throughout the seasons because of rotation. Brian states that stars change throughout the season because of revolution. Who is right?
