(K-4) The sun, moon, stars, clouds, birds, and airplanes all have properties, locations, and movements that can be observed and described. (K-4)< Most objects in the solar system are in regular and predictable motion. Those motions explain phenomena such as the day, the year, phases of the moon, and eclipses. (5-8) National Math Standards Understand measurable attributes of objects and the units, systems, and processes of measurement. Apply appropriate techniques, tools, and formulas to determine measurements.   This Season Teachers Kids Orientation Registration Search Copyright 1997-2008 Journey North. All Rights Reserved.
