SC15.8.15

Analyze and interpret data from experiments to determine how various factors affect energy transfer as measured by temperature (e.g., comparing final water temperatures after different masses of ice melt in the same volume of water with the same initial temperature, observing the temperature change of samples of different materials with the same mass and the same material with different masses when adding a specific amount of energy).

Energy and Matter

Knowledge

Students know:
  • Various factors affect the transfer of energy.
  • The relationship between the temperature and the total energy of a system depends on the types, states, and amounts of matter present.
  • The amount of energy transfer needed to change the temperature of a sample of matter by a given amount depends on the nature of the matter, the size of the sample, and the environment.
  • Temperature is related to the average kinetic energy of particles of matter.
  • Temperature, when measured in Kelvin, is directly proportional to average kinetic energy.

Skills

Students are able to:
  • Organize given data to allow for analysis and interpretation to determine how various factors affect energy transfer.
  • Analyze the data to identify possible causal relationships between various factors and energy transfer.
  • Interpret patterns observed from the data to provide causal accounts for events and make predictions for events by constructing explanations.

Understanding

Students understand that:
  • The relationship between the temperature and the total energy of a system depends on the types, states, and amounts of matter present.
  • Various factors, such as the state of matter, the amounts of matter present, and the environment, affect the amount of energy transfer needed to change the temperature of a sample of matter. A measure of temperature can indicate the amount of energy transfer.
