Module: Energy Transfer in Motion
DCI: PS3.B (B) The amount of energy transfer needed to change the
temperature of a matter sample by a given amount depends on the nature of the
matter, the size of the sample, and the environment.
PE: MS-PS3-4 Plan an investigation to determine the relationships
among the energy transferred, the type of matter, the mass, and the change in
the average kinetic energy of the particles as measured by the temperature of
the sample.
[Clarification
Statement: Examples of experiments could include comparing final water
temperatures after different masses of ice melted in the same volume of water
with the same initial temperature, the temperature change of samples of
different materials with the same mass as they cool or heat in the environment,
or the same material with different masses when a specific amount of energy is
added.] [Assessment Boundary: Assessment does not include calculating the total
amount of thermal energy transferred.]
The ideas in this standard are:
- the amount of energy transfer required to change the temperature of a substance depends on the specific material, how much of it is present, and the kind of environment it is in.
In order to write to the PE, we can have general questions about which aspects of an investigation will provide the kind of results that would support these ideas, we can ask which kinds of things to change in order to provide sufficient evidence, etc.
Possible Question Starters:
"Which of the following factors contributes to the amount of energy required to change the temperature of a sample of water by 10 degrees C?"
correct answer - the amount of water in the sample
incorrect answer - the source of the sample of water
"Students place different masses of ice into three beakers containing the same volume of water at the same initial temperature. The three beakers are placed on Which of the following would provide evidence that the sample size of the material affects the amount of energy required to change its temperature?"
correct answer - the sample of water containing the largest mass of ice cubes
