Thermochemistry Unit: How do Hot and Cold Packs Work?

Type of Resource



This unit addresses Physical Science PE HS-PS1-4 and Engineering Design PE of HS-WTS1-3 by engaging students in developing models around energy transfer and thermochemistry. Students will connect the energy changes at the particulate level through simulations to the macro level in terms of system and surrounds. Students plan and carry out investigations as performance tasks, analyze the data through collaborative group work and engage in research to find the best material for the hand warmers. S

Performance Expectations

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.
