I scream, you scream we all scream for ICE CREAM!! Everyone loves ice cream and kids love making it.
In this presentation we look at how you can teach some kinetic molecular theory, intermolecular forces and even heats of reaction/calorimetry while making ice cream.
This lesson has been done with grade 9 applied level classes as well as grade 11 University Prep Chemistry. It can easily be tailored for senior physics and chemistry.
Students get a chance to see how state of matter affects temperature (using the PASCO Wireless Temperature Sensor), in real time, and how adding salt to ice can drop the temperature even further even though it is changing into a liquid! We then do some simple calorimetry with different forms of food to get an idea of how much energy is stored in them.
