This year, the winter solstice takes place on Thursday, Dec. 22 at 12:30 a.m. EST. The winter solstice marks the day when winter officially starts in the Northern Hemisphere and when days start to become incrementally longer. Do you understand why this happens? Find out at the Chandra website and then incorporate the information into the NES lessons Heat Transfer: MESSENGER -- My Angle on Cooling (grades 5-8), Analyzing Solar Energy Graphs: MY NASA DATA (grades 9-12), and Temperature and Earth Climate: Modeling Hot and Cold Planets (grades 7-9).
