Overview

Students will be introduced to calorimetry via a simulation. The simulation will guide them through choosing an appropriate material for the calorimeter in order to prevent heat loss to the environment and will also show students what occurs on a microscopic level inside the calorimeter itself.

After students understand the heat that is transferred inside the calorimeter, they will be shown how to calculate the heat absorbed by or transferred from the water in the calorimeter using the formula:

qsolution = msolution • Cs solution • ∆T

    • [HS-PS1-4] Develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy.
    • [HS-PS3-2] Develop and use models to illustrate that energy at the macroscopic scale can be accounted for as a combination of energy associated with the motions of particles (objects) and energy associated with the relative positions of particles (objects)
