What is a hyperdoc? It is an interactive document with hyperlinks to learning opportunities and activities. This activity teaches students about heat energy and heat transfer (conduction, convection, radiation). Students will learn, practice, and apply what they know about heat transfer through multiple activities. Some of these include true/false, two truths and a lie, sorting, writing, and more!BONUS: A printable worksheet is included at the end of the activity. Great for extra practice! There
