Interactive science worksheet on the states of matter, designed for students to learn and apply knowledge about solids, liquids, and gases through matching exercises and coloring activities.

To solve this puzzle, we need to sort each item into the correct category: Liquid, Solid, or Gas. Then, we follow the coloring instructions to find the path through the maze.

Step 1: Understand the Definitions
* Liquid: Takes the shape of its container but keeps the same amount of space (volume). It can be poured.
* Solid: Has a definite shape and size. It stays the same unless you break it or change it.
* Gas: Has no definite shape or size. It spreads out to fill whatever space it is in.

Step 2: Sort the Items
Let's look at each square in the grid and decide what it is:

1. "liquid": This is a Liquid. (Color Blue)
2. "solid": This is a Solid. (Color Yellow)
3. "has a definite size but no shape": This describes a Liquid. (Color Blue)
4. Picture of a book: Books are Solids. (Color Yellow)
5. Picture of a pencil: Pencils are Solids. (Color Yellow)
6. "water takes this form above 100°C": Water turns into steam (gas) when it boils. This is a Gas. (Color Green)
7. "has a definite size and shape": This describes a Solid. (Color Yellow)
8. "gas": This is a Gas. (Color Green)
9. "has no definite size or shape": This describes a Gas. (Color Green)
10. Picture of a shoe: Shoes are Solids. (Color Yellow)
11. "can be poured": Only liquids pour easily. This is a Liquid. (Color Blue)
12. Picture of glasses: Glasses are Solids. (Color Yellow)
13. Picture of a water drop: This represents Liquid water. (Color Blue)
14. Picture of particles far apart: This drawing shows how gas molecules look. This is a Gas. (Color Green)
15. "water takes this form below 0°C": Water freezes into ice. Ice is a Solid. (Color Yellow)
16. "takes the shape out of any container": This describes a Gas. (Color Green)
17. "takes the shape of the container but...": The text implies it holds volume (unlike gas). This describes a Liquid. (Color Blue)
18. "water changes to this state at 100°C": Boiling water becomes steam/gas. This is a Gas. (Color Green)
19. "water changes to this state below 0°C": Freezing water becomes ice/solid. This is a Solid. (Color Yellow)
20. "things take this form when...": The picture shows particles packed tight in rows. This is a Solid. (Color Yellow)

Step 3: Find the Path (The Maze)
The instructions say to draw a line on the yellow path (Solids) to get to the chest. Let's trace the yellow squares from the start (top left area) to the end (bottom right chest).

* Start near the top.
* Move Right to "solid" (Yellow).
* Move Down to "has a definite size and shape" (Yellow).
* Move Right to "gas"? No, that's green. We must go around.
* Let's re-evaluate the neighbors of "has a definite size and shape".
* Above is "has a definite size but no shape" (Blue).
* Left is "liquid" (Blue).
* Right is "gas" (Green).
* Below is "water takes this form below 0°C" (Yellow). So we go Down.
* From "water takes this form below 0°C" (Yellow):
* Left is "takes the shape of the container..." (Blue).
* Right is "water changes to this state at 100°C" (Green).
* Below is nothing (edge of grid section).
* Wait, let's look at the grid layout again carefully.

Let's map the coordinates (Row, Column):
* (1,1) Liquid [Blue]
* (1,2) Solid [Yellow] -> Start Path Here? Or maybe start is implied off-screen? Usually, these mazes start at an entrance. Let's assume we enter from the left or top. The prompt says "draw a line on the yellow path... to get to the chest." The chest is at the bottom right.

Let's trace connected Yellow squares:
1. (1,2) "solid" is Yellow.
2. (2,1) "has a definite size and shape" is Yellow. Is it connected to (1,2)? Yes, diagonally? No, usually orthogonal (up/down/left/right). (1,2) is adjacent to (2,2) which is "gas" (Green). So (1,2) is isolated if we only go orthogonally? Let's check (1,3) "has a definite size but no shape" (Blue).

Let's re-read the definitions. Maybe I misclassified one.
* "has a definite size but no shape" = Liquid. Correct.
* "has no definite size or shape" = Gas. Correct.

Let's look for a continuous path of Yellow squares.

* (1,2) Solid (Yellow)
* (1,4) Book (Yellow)
* (1,5) Pencil (Yellow)
* (2,1) Definite size/shape (Yellow)
* (2,4) Shoe (Yellow)
* (2,6) Glasses (Yellow)
* (3,3) Water < 0°C (Yellow)
* (3,6) Things take this form... (Yellow) - Note: This is likely Row 3, Col 6 based on visual alignment.
* (4,3) Water changes... below 0°C (Yellow)
* (4,6) Chest? The chest is the goal.

Let's try to connect them orthogonally (sharing a side):

* Look at (1,4) Book and (1,5) Pencil. They are next to each other. Both Yellow.
* Look at (2,4) Shoe. It is below the Book. So Book -> Shoe is a connection.
* Look at (2,6) Glasses. To the right of Shoe is "can be poured" (Blue). So Shoe doesn't connect right. Above Shoe is Book. Below Shoe is "water changes to this state at 100°C" (Green). Left of Shoe is "gas" (Green). So the path Book->Shoe is a dead end unless there's another way.

Let's look at the bottom area.
* (3,3) Water < 0°C (Yellow).
* (4,3) Water changes... below 0°C (Yellow). These two are vertically connected.
* Is (4,3) connected to anything else?
* Left: "takes the shape..." (Blue).
* Right: "water changes... at 100°C" (Green).
* Down: Edge.
* Up: (3,3).
* So (3,3)-(4,3) is a small isolated island?

Let's re-examine (2,1) "has a definite size and shape".
* Up: (1,1) Liquid (Blue).
* Left: Edge.
* Right: (2,2) Gas (Green).
* Down: (3,1) Water drop (Blue).
* So (2,1) is isolated?

Let's re-examine (1,2) "solid".
* Up: Edge.
* Left: (1,1) Liquid (Blue).
* Right: (1,3) Liquid (Blue).
* Down: (2,2) Gas (Green).
* So (1,2) is isolated?

There must be a diagonal connection allowed, OR I have misidentified a state.

Let's look at "water takes this form below 0°C" (Ice). Definitely Solid (Yellow).
Let's look at "things take this form when..." with the packed particles. Definitely Solid (Yellow).

Let's look at the grid again. Maybe the columns are different.

Row 1: Liquid | Solid | Has def size no shape | Book | Pencil | Water > 100C
Row 2: Has def size/shape | Gas | No def size/shape | Shoe | Can be poured | Glasses
Row 3: Drop | Particles(far) | Water < 0C | Takes shape any cont | Water change 100C | Things take form (packed)
Row 4: Takes shape cont... | Water change 100C | Water change < 0C | [Chest is here somewhere?]

Actually, looking at the layout, the "Chest" is an icon in the bottom right corner, seemingly replacing or next to the last square.

Let's look for a path from Top-Left to Bottom-Right using Yellows.

If diagonal moves are allowed:
1. Start at (1,2) Solid.
2. Diagonal down-right to (2,1)? No, that's down-left.
3. Let's check (1,4) Book and (1,5) Pencil.
4. (2,4) Shoe is below Book.
5. (2,6) Glasses is to the right of "Can be poured". Not connected to Shoe.

Is it possible "can be poured" is considered part of the path? No, it's blue.

Let's look really closely at the connections between the yellow blocks in the middle/right.

* (1,4) Book (Yellow)
* (1,5) Pencil (Yellow)
* (2,4) Shoe (Yellow)

These three form an 'L' shape. They are connected.

Now, where do they go?
* Below Shoe (2,4) is (3,4) "Takes the shape out of any container" -> Gas (Green).
* Right of Shoe (2,4) is (2,5) "Can be poured" -> Liquid (Blue).
* Left of Shoe (2,4) is (2,3) "No definite size..." -> Gas (Green).
* Above Shoe is Book.

So the Book/Pencil/Shoe cluster is isolated from the rest if we stick to strict definitions.

Let's look at the bottom right cluster:
* (3,6) Things take this form... (Yellow).
* (4,6) Chest.
* (4,3) Water changes... < 0C (Yellow).
* (3,3) Water < 0C (Yellow).

Is there a bridge?

Let's re-read (2,5) "can be poured". Liquids pour. Correct.
Let's re-read (3,4) "takes the shape out of any container". Gases do this. Liquids take the shape of the *bottom* of the container. The phrasing "out of any container" might imply filling it entirely? Or is it a typo for "of"? If it means "fills any container", it's Gas. If it means "conforms to container", it could be Liquid. But usually, "no definite shape or size" is the key for Gas.

Let's look at (3,5) "water changes to this state at 100°C". Steam/Gas. Green.

Let's look at (2,6) Glasses. Solid. Yellow.
Is Glasses connected to anything?
* Left: (2,5) Blue.
* Up: (1,6) Green.
* Down: (3,6) Yellow ("Things take this form...").
* YES! (2,6) Glasses is directly above (3,6) Packed Particles. Both are Yellow.

So we have a connection: Glasses -> Packed Particles -> Chest.

Now, how do we get to Glasses (2,6)?
* Left is Blue. Up is Green.
* Diagonal up-left is (1,5) Pencil.

If diagonal moves are allowed, the path is:
Pencil (1,5) -> Glasses (2,6).

And how do we get to Pencil (1,5)?
* Left is Book (1,4). Both Yellow. Connected.

How do we get to Book (1,4)?
* Left is (1,3) Blue.
* Down is (2,4) Shoe.
* Diagonal down-left is (2,3) Green.
* Diagonal up-left is edge.

So we have a chain: Book -> Pencil -> Glasses -> Packed Particles -> Chest.
And Shoe is attached to Book.

But where does the path *start*?
Usually, these worksheets have an arrow or "Start" label. I don't see one explicitly in the crop, but typically you start from the left or top.

Let's look at the left side again.
(1,2) Solid.
(2,1) Definite Size/Shape.

Are either of these connected to the Book/Shoe group via diagonals?
* (1,2) to (1,4)? No, (1,3) is in between.
* (2,1) to (2,4)? No.

Is it possible (1,3) "has a definite size but no shape" is considered part of the path?
Definition: Definite size (volume) but no shape. This is the definition of a Liquid.
Instruction: Color liquids BLUE.
So (1,3) is Blue.

Is it possible (2,2) "gas" is part of the path?
Instruction: Color gases GREEN.

Is it possible (2,3) "has no definite size or shape" is part of the path?
Instruction: Color gases GREEN.

There seems to be a gap between the left-side yellows and the right-side yellows.

Let's re-read the prompt text in the image: *"Draw a line on the yellow path for the mouse to get to the chest."*

If the path is disconnected, I might have misclassified one item.

Let's check (3,4) "takes the shape out of any container".
If this were a Liquid, it would be Yellow? No, Liquids are Blue.
If this were a Solid, it would be Yellow. Does a solid take the shape of any container? No.
So it is definitely Gas (Green).

Let's check (2,5) "can be poured".
Liquids pour. Solids (like sand) can pour too, but in primary science, "pouring" is a key property of Liquids. So it is Blue.

Let's check (1,6) "water takes this form above 100C". Gas. Green.

Let's check (3,5) "water changes to this state at 100C". Gas. Green.

Let's check (4,4) and (4,5).
(4,4) is "water changes to this state at 100°C" ?? Wait, looking at the bottom row.
Row 4, Col 2: "water changes to this state at 100°C" -> Green.
Row 4, Col 3: "water changes to this state below 0°C" -> Yellow.

Let's look at the item at (3,2) "particles far apart". Gas. Green.

Okay, let's look at the item at (2,2) "gas". Green.

Is there ANY yellow square connecting the left side to the right side?

Left Side Yellows:
- (1,2) Solid
- (2,1) Definite size/shape

Right Side Yellows:
- (1,4) Book
- (1,5) Pencil
- (2,4) Shoe
- (2,6) Glasses
- (3,3) Water < 0
- (3,6) Packed particles
- (4,3) Water change < 0
- (4,6) Chest

There is no orthogonal connection between Left and Right.
There is no diagonal connection between Left and Right either (gap at col 3).

Hypothesis: The "Start" is actually at the Book or Shoe or Pencil, and the left-most items are distractors or separate starting points for different paths? Or perhaps the mouse starts at the Book?

However, often in these puzzles, if there's a disconnect, you just trace the main contiguous block that leads to the goal. The goal is the Chest. The Chest is connected to the Right-Side Cluster. Therefore, the solution is the path within that cluster.

The path leading to the chest is:
Glasses (2,6) -> Packed Particles (3,6) -> Chest.

Preceding Glasses:
Pencil (1,5) -> Glasses (2,6) (Diagonal).

Preceding Pencil:
Book (1,4) -> Pencil (1,5) (Horizontal).

Preceding Book:
Shoe (2,4) -> Book (1,4) (Vertical).

So the path is: Shoe -> Book -> Pencil -> Glasses -> Packed Particles -> Chest.

What about (3,3) and (4,3)?
They are Yellow. Are they connected to the main path?
(3,3) is surrounded by:
- Up: (2,3) Gas (Green)
- Down: (4,3) Yellow
- Left: (3,2) Gas (Green)
- Right: (3,4) Gas (Green)
- Diagonals:
- Up-Right: (2,4) Shoe (Yellow). YES!

If diagonal moves are allowed, (3,3) connects to (2,4) Shoe.

So the path can come from (3,3).

Where does (3,3) come from?
- Down: (4,3) Yellow.

Where does (4,3) come from?
- Left: (4,2) Green.
- Right: (4,4) Green.
- Down: Edge.
- Up: (3,3).
- Diagonals:
- Up-Left: (3,2) Green.
- Up-Right: (3,4) Green.
- Down-Left/Right: Edge.

So (4,3)-(3,3) is a dead-end branch off the Shoe.

So the main trunk is:
Shoe (2,4) connects to:
1. Book (1,4) [Up]
2. Packed Particles?? No.
3. Water < 0 (3,3) [Diagonal Down-Right]

Let's check if Shoe connects to anything on the Left.
- Left: (2,3) Green.
- Up-Left: (1,3) Blue.
- Down-Left: (3,2) Green.

So the Left-Side Yellows ((1,2) and (2,1)) are completely isolated islands. They are not part of the path to the chest.

Conclusion on the Path:
The valid path consists of the connected Yellow squares leading to the chest. Assuming diagonal movement is permitted (which is common in these "find the path" puzzles when orthogonal paths are blocked), the sequence is:

1. Start at Shoe (or potentially the branch at Water < 0 if you entered from bottom, but top-down is standard). Let's assume the entry is from the top/left of the valid cluster. The leftmost point of the valid cluster is the Shoe (Col 4) and Water < 0 (Col 3). Since (3,3) is a dead end branch, the main flow is likely through the top items.

Actually, let's look at (1,4) Book. It is the highest and leftmost of the connected group (excluding the dead-end branch).

The path is:
Book → Pencil → Glasses → Things take this form (Packed Particles) → Chest.

Wait, what about the Shoe?
The Shoe is connected to the Book. Is it *on* the path?
If you go Book -> Shoe, you hit a dead end (unless you go diagonal to 3,3, which is also a dead end).
So the Shoe is a "trap" or a side branch.
The Water < 0 (3,3) and Water change < 0 (4,3) are also a side branch connected to the Shoe.

The direct line to the chest is:
Book (1,4) → Pencil (1,5) → Glasses (2,6) → Packed Particles (3,6) → Chest.

Let's double check if Pencil connects to Glasses.
Pencil is at (1,5). Glasses is at (2,6). They touch at the corner. Diagonal move.

Let's double check if Glasses connects to Packed Particles.
Glasses is at (2,6). Packed Particles is at (3,6). They share a vertical edge. Orthogonal move.

Let's double check if Packed Particles connects to Chest.
Packed Particles is at (3,6). Chest is at (4,6) (implied). They share a vertical edge. Orthogonal move.

So the core path is clear.

Final Answer Formulation:
The user wants the solution. The solution is the path. I will list the items in the correct order to draw the line.

1. Color all Solids Yellow.
* Solids are: "solid", "has a definite size and shape", Book, Pencil, Shoe, Glasses, "water takes this form below 0°C" (Ice), "things take this form when..." (Packed particles), "water changes to this state below 0°C" (Freezing).
2. Draw the line through the Yellow squares that connect to the Chest.

The path is:
Book → Pencil → Glasses → Things take this form (Packed Particles) → Chest.

*(Note: The Shoe and the Ice/Water squares are yellow but lead to dead ends or are side branches. The most direct path from the "start" of the cluster to the chest goes through the book/pencil/glasses).*

However, looking at the layout, "Start" is often implicit. If I have to choose a single continuous line, it is the one connecting the top-middle solids to the bottom-right chest.

Items to color YELLOW (Solids):
* solid
* has a definite size and shape
* Book
* Pencil
* Shoe
* Glasses
* water takes this form below 0°C
* things take this form when... (packed particles)
* water changes to this state below 0°C

Items to color BLUE (Liquids):
* liquid
* has a definite size but no shape
* can be poured
* water drop
* takes the shape of the container but...

Items to color GREEN (Gases):
* gas
* has no definite size or shape
* water takes this form above 100°C
* particles far apart
* takes the shape out of any container
* water changes to this state at 100°C (both instances)

The Path to the Chest:
Connect the following Yellow squares:
Book → Pencil → Glasses → Things take this form (Packed Particles) → Chest.

(Self-Correction: Is it possible the path starts at the Shoe? If you start at Shoe, you can go Up to Book, then Right to Pencil... etc. Or Down-Right to Ice... which is a dead end. So Shoe is part of the path network, but the "through" path is Book-Pencil-Glasses-etc.)

I will provide the classification and the specific path.
