Ice
Ice is the solid form of water, which occurs when water molecules align in a crystalline structure. It is formed when the temperature of water reaches 0 degrees Celsius (32 degrees Fahrenheit) or below, causing the molecules to slow down and form a rigid lattice structure. This lattice structure gives ice its characteristic hardness and transparency.
Properties of Ice:
- Hardness: Ice is a hard and rigid substance, making it useful for preserving food and creating structures in cold regions.
- Transparency: Ice is transparent, allowing light to pass through it. This property is utilized in making ice sculptures and in the formation of natural ice formations.
- Floats on water: Ice is less dense than liquid water, so it floats on the surface of water. This is important for the survival of aquatic organisms during winter.
- Melting point: Ice melts into liquid water at 0 degrees Celsius (32 degrees Fahrenheit).
Study Guide:
- What is the temperature at which water freezes and turns into ice?
- What is the structure of ice?
- How does the density of ice compare to that of liquid water?
- What is the melting point of ice?
Answer: Water freezes at 0 degrees Celsius (32 degrees Fahrenheit).
Answer: Ice has a crystalline lattice structure formed by the alignment of water molecules.
Answer: Ice is less dense than liquid water, causing it to float on the surface of water.
Answer: Ice melts into liquid water at 0 degrees Celsius (32 degrees Fahrenheit).

LIFE SCIENCE
From Molecules to Organisms: Structures and Processes
Create representations to explain the unique and diverse life cycles of organisms other than humans (e.g., flowering plants, frogs, butterflies), including commonalities such as birth, growth, reproduction, and death.
Unity and Diversity
Construct an argument from evidence to explain the likelihood of an organism’s ability to survive when compared to the resources in a certain habitat (e.g., freshwater organisms survive well, less well, or not at all in saltwater; desert organisms survive well, less well, or not at all in woodlands).
Create models that illustrate how organisms and their habitats make up a system in which the parts depend on each other.
