Heating and cooling curves
Content is AI-assisted and continuously improved through educator review
Learning Objective
Students will be able to explore heating and cooling curves.
In this lesson, we'll explore heating and cooling curves. Scientific inquiry allows us to investigate and explain natural phenomena.
Energy is the capacity to do work. It takes many forms: Kinetic energy (KE = ½mv²) is energy of motion; Potential energy (PE = mgh for gravitational) is stored energy. The Law of Conservation of Energy states that energy cannot be created or destroyed—only converted between forms (thermal, chemical, electrical, mechanical, light, nuclear). Heat (thermal energy) flows from warmer to cooler objects via conduction (direct contact), convection (fluid movement), and radiation (electromagnetic waves). Waves transfer energy without transferring matter; characteristics include wavelength, frequency, and amplitude. Electromagnetic spectrum (from longest to shortest wavelength): radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, gamma rays. Sound waves are mechanical waves requiring a medium (cannot travel in vacuum).
As you work through today's material, pay attention to the examples and try to identify the patterns or strategies being used. This will help you apply these concepts to new problems.
Take notes on key points and make connections to what you've already learned in previous lessons.

Teaching Tip
For this age group: Balance direct instruction with collaborative activities. Allow students to explain their thinking and make connections to prior knowledge when exploring heating and cooling curves.
