Video Description:  Volcanoes play a role in how Earth looks today. Thanks to NASA's missions, we know more about volcanoes in our solar system. Studying volcanoes can teach us about the interior properties of the planets and moons. Learn how the slope equation is used to identify how a volcano was formed.  Video Length:  4:46.NASA eClipsTM is a suite of online student-centered, standards-based resources that support instruction by increasing STEM literacy in formal and nonformal settings.  These free digital and downloadable resources inform and engage students through NASA-inspired, real-world connections.NASA eClips Real World segments (grades 6-8) connect classroom mathematics to 21st Century careers and innovations.  They are designed for students to develop an appreciation for mathematics through real-world problem solving.

After reading about physical properties of matter, I wanted students to have a chance to experience what the different vocabulary words meant and gain some common experiences so that we would be able to reference these experiences in later classes. My students were also struggling with the new vocabulary words as well as the idea that melting temperature was a physical property. These six stations are designed for students to rotate through independently in small groups. The teacher will be at the gallium melting demonstration station throughout the activity while also monitoring students' progress around the room. At each station students will create a Frayer Model for the vocabulary term that includes the term, definition, a drawing, a synonym, an example, and a sentence that uses the term.
