The first lesson of two on Ancient Rome, students examine physical maps of Rome to identify physical features that provided security for the site of Rome. In addition, students examine the relative location of Rome and its connections within the Mediterranean Basin and beyond. The second segment of the lesson examines the expansion of the Roman Empire through time and the role of physical features in facilitating or hindering that expansion. Key questions: What are the physical features of Rome?;
How did the physical geography of Rome influence its development?

NASA eClips Our World:  Where Do We Find Extremophiles?Video Description:  Where do we find extremophiles? We look for environments that push the limits for ordinary living organisms. NASA conducts analog testing in these extreme environments to better understand life on Earth and identify the potential for life in the universe.  Video Length:  3:25. 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 Our World videos (grades 3-5) help students understand the differences between science (the natural world) and engineering (the designed world).  These video segments supplement elementary learning objectives not only in science, technology, engineering and mathematics, but also in reading, writing, visual and performing arts.

NASA eClips Real World:  Food Security -- Monitoring Crops from SpaceVideo Description:  Discover how NASA's Earth-observing satellites gather data to monitor food growth. Dr. Inbal Becker-Reshef describes how mathematics is used to interpret satellite data and describe vegetation and crop yield. Dr. Hannah Kerner shares how algorithms and models use NASA data to describe and predict food supply and food shortages. This work through NASA Harvest provides tools for farmers and governments to describe and predict food security worldwide. Video Length:  5:25.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.

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.
