In accordance with the Connecticut curriculum standards for Science in grades K - 4, after completing this unit, students will be able to identify objects in the sky, such as the Moon, identify and describe the patterns of movement of objects in the sky from day to day and season to season and explain the characteristics and patterns of movement of the Moon. Students will recognize that sometimes scientists have different explanations for the same set of observations, which usually leads to additional observations to resolve the differences. Students will describe how the Moon looks a little different every day, but looks the same about every four weeks. Students will describe how the astronauts use spacecraft for travel and how some astronauts have even traveled to the Moon and back. Through this exercise students will recognize that information and photographs from orbiting spacecraft have added to our knowledge of the Earth and the universe.
