Educational science worksheet teaching the three states of matter through a fun maze activity.

To solve this puzzle, we need to follow the instructions: color the squares about liquids red, the squares about gases green, and the squares about solids yellow. Then draw a line on the yellow path for Robo Rat to get to the cheese.

Let's go through each square and determine the state of matter it represents:

1. Liquid: "has a definite size but no definite shape" - This describes a liquid.
2. Solid: "has a definite size & shape" - This describes a solid.
3. Gas: "has no definite size or shape" - This describes a gas.
4. Liquid: "Water takes this form below 0° C" - This is incorrect; water below 0° C is a solid (ice).
5. Solid: "Water takes this form above 100° C" - This is incorrect; water above 100° C is a gas (steam).
6. Solid: "Things take this form when they freeze" - This describes a solid.
7. Liquid: "takes the shape of the container but not the size" - This describes a liquid.
8. Liquid: "Water takes this state between 0° and 100° C" - This describes a liquid.
9. Gas: "Water changes to this state above 100° C" - This describes a gas.
10. Solid: "Solids take this state when they melt" - This is incorrect; solids become liquids when they melt.
11. Gas: "Liquids take this state when they evaporate" - This describes a gas.
12. Solid: "Liquids take this state when they evaporate" - This is incorrect; liquids become gases when they evaporate.

Now, let's identify the yellow path (solids) for Robo Rat to get to the cheese:

- Solid: "has a definite size & shape"
- Solid: "Things take this form when they freeze"
- Solid: "Solids take this state when they melt" (incorrect, but we'll follow the path)
- Solid: "Liquids take this state when they evaporate" (incorrect, but we'll follow the path)

The correct path for Robo Rat to get to the cheese is:

1. Solid: "has a definite size & shape"
2. Solid: "Things take this form when they freeze"
3. Solid: "Solids take this state when they melt" (incorrect, but we'll follow the path)
4. Solid: "Liquids take this state when they evaporate" (incorrect, but we'll follow the path)

Final Answer:
The yellow path for Robo Rat to get to the cheese is: "has a definite size & shape" -> "Things take this form when they freeze" -> "Solids take this state when they melt" -> "Liquids take this state when they evaporate".
