Problem 1: Star Color Chart

#### Question:
Did you know that stars come in different colors? The color of a star depends on how hot it is. Red stars are the coolest. Blue stars are the hottest. Color and label the stars below from coolest to hottest.

#### Stars Provided:
- Red
- Orange
- Green
- White

#### Solution:
The temperature of stars determines their color. Here is the order from coolest to hottest:
1. Red: Coolest stars.
2. Orange: Slightly hotter than red stars.
3. White: Even hotter than orange stars.
4. Green: Not typically observed as a star color in reality, but if we follow the sequence, green would be hotter than white (though this is not accurate in real astronomy).

So, the correct order is:
- Coolest: Red
- Hottest: Green

#### Answer:
- Coolest: Red
- Hottest: Green

Problem 2: Comparing the Sun to Other Stars

#### Question:
Compared to other stars in the sky, our sun looks:
a. smaller and brighter
b. larger and brighter
c. smaller and dimmer
d. larger and dimmer

#### Solution:
The Sun is an average-sized star in terms of size and brightness compared to other stars in the universe. However, because it is much closer to us than any other star, it appears much larger and brighter in the sky.

#### Answer:
b. larger and brighter

Problem 3: Groups of Stars Forming Shapes

#### Question:
Groups of stars that form shapes or clusters in the sky are called:
a. asteroids
b. shooting stars
c. comets
d. constellations

#### Solution:
Constellations are specific groupings of stars that form recognizable patterns or shapes in the night sky. These patterns have been named and used for navigation and storytelling throughout history.

- Asteroids: Small rocky objects orbiting the Sun.
- Shooting stars: Meteors burning up in Earth's atmosphere.
- Comets: Ice and dust bodies that orbit the Sun and sometimes develop tails.
- Constellations: Patterns of stars in the sky.

#### Answer:
d. constellations
