Lesson: Heat

Dive into the world of heat as a form of energy, measuring in Joules. Discover how heat influences solids, liquids, and gases through engaging experiments using Bunsen burners and various equipment. Observe changes in color, volume, and temperature while investigating the unique properties of different substances when exposed to heat. This educational lesson will challenge your understanding of the mechanisms behind heat transfer and its impact on physical states of matter.
