Problem Analysis:
The worksheet is from a Primary 5 Science lesson titled "Water and changes of states." The task involves recalling the three states of matter and determining if water is a form of matter. The images provided in the worksheet show different forms of water, which are likely meant to illustrate the three states.
Key Concepts:
1.
Three States of Matter:
- Solid
- Liquid
- Gas
2.
Water as a Form of Matter:
- Water is indeed a form of matter because it has mass and occupies space. It can exist in all three states (solid, liquid, gas).
3.
Images in the Worksheet:
- The first image shows ice cubes, representing
solid water.
- The second image shows water droplets, representing
liquid water.
- The third image shows hot air balloons, which may represent
water vapor (gas state), although this is not explicitly clear from the image alone.
Solution Explanation:
#### Step 1: Recall the Three States of Matter
The three states of matter are:
1.
Solid: A state where particles are closely packed and have a fixed shape and volume. Example: Ice.
2.
Liquid: A state where particles are loosely packed and have a fixed volume but take the shape of their container. Example: Water.
3.
Gas: A state where particles are widely spaced and have neither a fixed shape nor a fixed volume. Example: Water vapor.
#### Step 2: Identify the States of Water in the Images
-
Image 1 (Ice Cubes): This represents
solid water (ice).
-
Image 2 (Water Droplets): This represents
liquid water.
-
Image 3 (Hot Air Balloons): While not directly showing water vapor, hot air balloons often use heated air, which can include water vapor. However, this image is more symbolic than literal for the gas state of water.
#### Step 3: Confirm if Water is a Form of Matter
Water is definitely a form of matter because:
- It has mass.
- It occupies space.
- It can exist in all three states of matter (solid, liquid, gas).
Final Answer:
1.
The three states of water are:
- Solid (Ice)
- Liquid (Water)
- Gas (Water Vapor)
2.
Water is a form of matter because it has mass and occupies space, and it can exist in all three states of matter.
\boxed{\text{Solid (Ice), Liquid (Water), Gas (Water Vapor); Yes, water is a form of matter.}}
