Students begin with an investigation into the structure of matter and how energy determines state of matter. This page is a high level look at key components of this lesson. ](https://www.knowatom.com/science-phenomena-videos/7th-grade-science/thermal-energy-and-particle-motion) [ VIEW LESSON ](https://www.knowatom.com/science-phenomena-videos/7th-grade-science/thermal-energy-and-particle-motion) [![](https://www.knowatom.com/hubfs/Grade/Screenshot%20(32).png) ](https://www.knowatom.com/science-phenomena-videos/7th-grade-science/mass-and-heat-transfer) ## [Mass and Heat Transfer In this unit, students explore phenomena of natural processes that cause Earth’s surface to change over time, analyzing how energy causes Earth’s matter to transform and cycle from one form to another. In this lesson, students investigate how Earth materials are continually being reshaped and reformed by multiple processes that are powered by energy from Earth’s hot interior and the sun.
