Temperature
Temperature is a measure of how hot or cold something is. It is a fundamental property of matter that reflects the average kinetic energy of the particles in a substance. Temperature is measured using a thermometer and is typically expressed in units such as degrees Celsius (°C) or degrees Fahrenheit (°F).
Key Concepts:
- Thermometer: An instrument used to measure temperature. It works on the principle that substances expand or contract with changes in temperature.
- Scales: Temperature can be measured on different scales, such as Celsius, Fahrenheit, and Kelvin. Celsius is commonly used in most of the world, while Fahrenheit is used in the United States. Kelvin is the standard unit of temperature in the scientific community.
- Heat Transfer: Temperature differences drive the transfer of heat from warmer objects to cooler objects. This process occurs through conduction, convection, and radiation.
- Effects of Temperature: Temperature influences various physical and chemical properties of substances, including their states of matter (solid, liquid, gas), solubility, and rates of chemical reactions.
Study Guide:
Here are some key points to remember when studying temperature:
- Understand the concept of temperature as a measure of the average kinetic energy of particles in a substance.
- Learn to convert between different temperature scales (e.g., Celsius to Fahrenheit or Kelvin).
- Explore the effects of temperature on different materials and processes, such as the behavior of gases, the melting and boiling points of substances, and the impact on biological systems.
- Practice using thermometers and interpreting temperature readings in various contexts.
- Examine real-world applications of temperature measurement, such as weather forecasting, cooking, and industrial processes.
Understanding temperature is essential for grasping a wide range of scientific phenomena and everyday experiences. By mastering the concept of temperature, you can better comprehend the behavior of matter and the processes that shape our world.

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.
