Product Highlights
- Investigate 3 different scenarios for obtaining thermal equilibrium and use the data as evidence to support a claim for the mechanism of heat transfer.
- High school teacher-led, student-engaged demonstration with reusable materials.
- Carolina Kits 3D®—Labs that use phenomena to support NGSS and 3-dimensional instruction.
Place a hot beverage outside on a cold day. Soon, the beverage cools to the temperature of the surrounding air. The colder the air, the faster the cooling seems to occur. Likewise, a cold beverage taken outside on a hot day warms to the ambient temperature. What determines how heat is transferred between objects and how quickly the transfer happens? What can that simple phenomenon tell us about energy transfer in general and about more complex systems that use heat to perform work? In this investigation, students explore the driving question, “What factors affect the rate of transfer of thermal energy?”
Time Requirement
Total, 150 minutes. Teacher prep, 30 minutes. Pre-lab, 30 minutes. Each investigative period, about 90 minutes.
Digital Resources
Includes 1-year access to digital resources that support 3-dimensional instruction for NGSS. Digital resources may include a teacher manual and student guide, pre-lab activities and setup videos, phenomenon videos, simulations, and post-lab analysis and assessments.

Learning Objectives
- Monitor or analyze the change in temperature of 2 samples of matter under various conditions.
- Perform graphical analysis of data related to the transfer of thermal energy.
- Explain what the experimental results indicate about factors that affect heat transfer.
Prerequisite Knowledge and Skills
Students should have an understanding of the definition of energy and the relationship between thermal energy and temperature. They should also be familiar with the kinetic theory of matter, the first and second laws of thermodynamics, and with the 3 methods of heat transfer: conduction, convection, and radiation.
