			<itunes:summary>NASA Connect video containing four segments as described below. NASA Connect segment explaining the foundations of astronomy and the how the Earth moves relative to the sun. This segment explains how the Earth&apos;s tilt creates the 4 seasons. NASA Connect segment explaining how the height of the sun relates to the growing seasons and the length of daylight. This segment describes how Ancient Egyptian and Greek cultures used astronomy in their lives. The segment also contains an activity for exploring how a gnomon works. In the activity students must track the shadows made by a gnomon in 30 minute intervals. The activity will teach students how the length of the shadows and the angles created by the gnomon are related to the position of the sun. NASA Connect segment that shows two examples of how the Navajo used used structures to track progress of the sun in the sky. NASA Connect segment describing the Ancient Mayan civilization and their accomplishments. This segment compares the Mayan counting system to the Roman counting system and has a brief exercise for students to add the numbers 21 and 33 using both systems.</itunes:summary>

			<itunes:summary>NASA Connect video containing four segments as described below. NASA Connect segment giving examples of how remote sensing is used. The end of the first segment asks student to define remote sensing and use it to describe objects across the room. NASA Connect segment defines remote sensing and explains how researchers use satellites to observe the Earth from space. This segment defines the electromagnetic spectrum and explains how satellites use different sensors to measure the invisible light reflected from Earth&apos;s surface. This segment also explores the definition of Geographic Information Systems or GIS. NASA Connect segment explaining the number lines and the rectangular coordinate system. This segement provides an interactive activity where students draw a number line and graph points on the number line. After graphing points on the number line the students are asked to draw a rectangular coordinate system and graph coordinate pairs in the four quadrants. Next the segment describes how rectangular coordinate systems are used in maps. The segment ends with a student exercise where students use covered shoe boxes to identify the topography of an environment their classmates created. NASA Connect segment explaining what archaeologists do. This segment covers how archaelogists reconstructed the historic environments of the Mayan and their agriculture practices. Archaelogists try to use the information from the past farming practice of the Mayan to save the rain forests.</itunes:summary>

			<itunes:author>Ron T. Brown</itunes:author>
			<itunes:summary>NASA Connect video containing five segments as described in the following. First segment of Good Stress explains the three types of stress: physical, mental and emotional. The first segment next asks students a series of inquiry based question about data. The first segment continues with an explanation of how data is collected, organized, analyzed and why data analysis is important. The Good Stress segment explains what scatter plots are and how graphing these plots show different trends. The first segment contains an activity that asks students to determine the trend in a scatter plot. Second segment of Good Stress explains the types of muscles in the body, why astronauts&apos; muscles weaken in space and some ways of taking care of your muscles. The Muscles segment describes the difference between skeletal muscle, smooth muscle, and cardiac muscle. The Muscles segment also explains the rehabilitation of astronauts returning from space. Third segment contains a program hands on activity that explores the effect of stress on muscles in the hand. The program hands on activity reviews scatterplots, box and whisker plots and stem and leaf plots. Fourth segment of Good Stress reviews what we have learned up to this point in the program. Fifth segment of Good Stress describes the different types of bones in the body and explains the purpose of the skeletal system. The Bones segment describes what bones are made out of and how bones interact with muscles in the body. The Bones segment discusses what people should do to maintain healthy bones. The fifth segment ends with a discussion of how much bone loss astronauts can expect when they spend time in space.</itunes:summary>

			<itunes:author>Ron T. Brown</itunes:author>
			<itunes:summary>NASA Sci Files video containing the 12 segments described below. First segment of the Ocean Odyssey describes tides and waves and how they are created by the gravitational forces of the sun and moon. Second segment of the Ocean Odyssey describes how the oceans formed and the role of salt in creating currents. Third segment of the Ocean Odyssey describes how the salinity and temperature of water increases its density.  The Density Current segment describes how the different densities of water in the ocean create currents. Fourth segment of the Ocean Odyssey describes surface currents, what role they have in the creation of climate and how they form. Fifth segment of the Ocean Odyssey describes the velocity of current. In the fifth segment the tree house detectives perform a series of experiments. In the first experiment they measured the velocity of current, in the second experiment they see who can swim the fastest against the current, and in the final experiment of this segment they test to see if people float at different speeds. Sixth segment of the Ocean Odyssey describes how oil is formed in the Earth. Seventh segment of the Ocean Odyssey describes how drilling companies produce and look for oil. Eighth segment of the Ocean Odyssey describes Ocean Topography and where oil seepage comes from. Ninth segment of the Ocean Odyssey describes Ocean Pressure and how that limits the depth to which people can dive. In the ninth segment they discuss alternative means of exploring deep parts of the ocean. Tenth segment of the Ocean Odyssey contains the Hands on Activity, in which students simulate an oil spill and try to clean it up in different ways. Eleventh segment of the Ocean Odyssey describes the impact of oil spills on the environment, how oil spills are tracked, and what is used to clean up oil spills. Twelfth segment of the Ocean Odyssey describes coastal currents and how they might effect oil spills and objects in the ocean.</itunes:summary>
