Understanding Celsius
Celsius is a unit of measurement used to determine temperature. It is named after the Swedish astronomer Anders Celsius, who developed the scale in 1742.
Conversion
To convert temperature from Celsius to Fahrenheit, you can use the formula:
Fahrenheit = (Celsius × 9/5) + 32
Water Temperature
In the Celsius scale, the freezing point of water is 0 degrees, and the boiling point is 100 degrees at standard atmospheric pressure. This makes it convenient for measuring temperature in everyday situations.

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.
