Here is the complete solution to the “Sky Colors” worksheet, including underlining the main points and answering all five questions in full sentences.

Underlined Main Points in the Paragraph:
*(Note: Since I can't physically underline in this format, I will list the key sentences or phrases that represent the main ideas. In practice, you would underline these directly on the worksheet.)*
1.
“The reason is that the mixture of particles in the atmosphere is constantly changing.”
2.
“Every color in the sky comes from the Sun.”
3.
“Sunlight is white, which means it is a mix of every color in the rainbow.”
4.
“But as it passes through the atmosphere, gases, dust, ice crystals, and water droplets split it into the various colors, bouncing some toward our eyes and absorbing others.”
5.
“Clear skies are blue because gases in the air reflect mostly blue light from the Sun.”
6.
“The sky gets paler when extra dust or moisture reflects other colors, diluting the blue.”
7.
“Sunsets are yellow (or red, if the air is dusty) because the Sun’s rays have to travel so far through the lower atmosphere that all the yellow light is absorbed.”
These sentences capture the core scientific explanation for why the sky changes color.

Answers to Questions (in complete sentences):
1. What color is sunlight?
Sunlight is white, which means it is a mix of every color in the rainbow.
2. Why is the sky blue?
The sky is blue because gases in the air reflect mostly blue light from the Sun.
3. What do you notice about the first four words? Why do you think they are set out this way?
The first four words — “Have you ever wondered…” — are written as a question to grab the reader’s attention and make them curious. This is a common writing technique to engage the audience right at the beginning by connecting with their own experiences or thoughts.
4. What kind of sentences introduce the passage?
The passage is introduced with two rhetorical questions that invite the reader to think about everyday observations — like why clear skies are sometimes deep blue and why sunsets vary in color. These questions help set up the topic and prepare the reader for the scientific explanation that follows.
5. Words such as the reason is, because, and which means tell us that this piece of writing does more than simply list facts. What else does it do?
These words show that the passage explains *why* things happen — not just *what* happens. It provides causes and effects, helping the reader understand the science behind sky colors. This makes the text explanatory and informative, rather than just descriptive or factual.
