Let's solve this worksheet step by step.

Part 1: Fill in the blanks

1. A ________ is a giant group of ________, gas and billions of ________.

- From the word bank, we know:
- "galaxy" is a giant group
- It contains stars, gas, and dust
- So:
A galaxy is a giant group of stars, gas and billions of dust.

> ✔ Answer:
> A galaxy is a giant group of stars, gas and billions of dust.

---

2. There are ________ main types of galaxies.

- The three main types of galaxies are: Spiral, Elliptical, and Irregular.
- So there are three main types.

> ✔ Answer:
> There are three main types of galaxies.

---

3. We live in a ________ shaped galaxy called the ________ ________.

- Our galaxy is the Milky Way, which is a spiral galaxy.
- Spiral galaxies have a disc-like shape with arms spiraling out from the center.

> ✔ Answer:
> We live in a spiral shaped galaxy called the Milky Way.

---

4. It is ________ than most galaxies in the ________.

- The Milky Way is larger than many galaxies, but not necessarily all.
- It's also considered older than some, but contextually, the phrase often refers to size.
- The universe contains many galaxies, so "Universe" fits here.
- Looking at the word bank: "larger", "Universe"

> ✔ Answer:
> It is larger than most galaxies in the Universe.

Now let’s analyze the images below.

---

Image 1: First Galaxy (Top)

This image shows a spiral galaxy with a central bulge and spiral arms. It appears well-structured, with visible dust lanes and star-forming regions.

- Name: Spiral Galaxy
- Shape: Spiral (or disc-shaped)
- Star type: Young stars (since spiral galaxies have active star formation)

> ✔ Answer:
> - Name: Spiral Galaxy
> - Shape: Spiral / Disc
> - Star type: Young stars

---

Image 2: Second Galaxy (Middle)

This galaxy has a more irregular, chaotic structure with no clear spiral or elliptical form. It looks like a cloud of stars and gas, possibly with clumps.

- This is an Irregular Galaxy.
- Shape: Irregular
- Star type: Often contains young stars due to ongoing star formation, though it can vary.

> ✔ Answer:
> - Name: Irregular Galaxy
> - Shape: Irregular
> - Star type: Young stars

---

Image 3: Third Galaxy (Bottom)

This galaxy has a distinct spiral pattern with bright arms swirling around a central core. It's a classic example of a spiral galaxy.

- Name: Spiral Galaxy
- Shape: Spiral
- Star type: Young stars (due to star-forming regions in the arms)

> ✔ Answer:
> - Name: Spiral Galaxy
> - Shape: Spiral
> - Star type: Young stars

✔ Final Answers:

#### Fill-in-the-blanks:

1. A galaxy is a giant group of stars, gas and billions of dust.
2. There are three main types of galaxies.
3. We live in a spiral shaped galaxy called the Milky Way.
4. It is larger than most galaxies in the Universe.

#### Image Analysis:

| Image | Name | Shape | Star Type |
|------|------|-------|-----------|
| 1 | Spiral Galaxy | Spiral / Disc | Young stars |
| 2 | Irregular Galaxy | Irregular | Young stars |
| 3 | Spiral Galaxy | Spiral | Young stars |

🔍 Notes:

- The word bank includes: *Spiral, Elliptical, Irregular, galaxy, three, larger, football, discs, odd, dust, Milky Way, Universe, older, young*
- "Football" and "odd" may be distractors; "football" could describe elliptical galaxies (like a rugby ball), but not used here.
- "Older" might apply to elliptical galaxies, which have mostly old stars — but none of the images shown are elliptical.
- All three images are either spiral or irregular — no elliptical shown.

✔ This completes the worksheet accurately!
