The simulation you were working with on page 2 models a calorimeter. The simulation allows you to choose the material to use for your calorimeter using the dropdown menu labeled "container-material".
Begin by hitting "setup” and then “run/pause”. Adjust the "sensor-radius" slider bar to 48, then press “place sensor” to add this to the inside of the container ensuring the sensor does not contact to walls of the container. Now adjust the "sensor-radius" slider bar to 4, then press “place sensor” to add this to the outside of the container, again ensuring the sensor does not contact to walls of the container.
You will choose one of the chemical processes available (either the separation of the ionic compound potassium iodide (KI) in water or the synthesis of calcium hydroxide, Ca(OH)2 , and subsequent production of hydrogen gas when solid calcium metal (Ca) is added to water) to determine the ideal material to use for your calorimeter. In order to observe the ionic compound separate in water, you will need to press the "Add KI" button; to observe the synthesis of calcium hydroxide and production of hydrogen gas, you will need to press the "Add Ca" button.
