You have been offered a job with NASA as an astronomy assistant. Your first task is to create a digital model and fact sheet about the Earth, moon and sun for future fourth graders at Sealston Elementary. Your audience is current third grade students, and you will be hired to share at a Universe Fair based upon your successful completion of the task.

Video Description:  In this close-up video, Begona Vila, Instrument Systems Engineer for the James Webb Space Telescope at NASA's Goddard Space Flight Center, describes her role in supporting the operations of the Webb telescope. The Webb telescope is currently the largest and most complex space telescope, set to look back in time and take pictures of the first galaxies and stars in the universe. In addition to her work on this historic project, Begona shares her love for reading, yoga, and exploring the outdoors. She highlights her interest in both science and art and her belief that humans share the need to explore and continuously learn.  Video length:  2:34.NASA eClips Ask SME: Close-up with a NASA Subject Matter Expert videos are professionally developed to capture a glimpse of NASA SME's personal interests and career journeys. Each can be used to spark student interest and broaden their ideas of the STEM workforce. Additional videos in this series can be found by searching GoOpenVA using "NASA eClips Ask SME".

Video Description:  What causes the phases of the Moon? From New Moon to Full Moon, the Earth-Sun-Moon system is responsible for the Moon’s changing phases. Learn more about rotation, revolution and this repeatable pattern. Video Length:  3:13. 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.
