Skills
  • support an argument (differences in apparent brightness of sun and other stars due to relative distances) #dok3
  • represent data (in graphical displays of daily and seasonal phenomena) #dok2
  • identify patterns (in data about day/night, shadows, and seasonal star appearance) #dok2
  • analyze graphical displays (to interpret daily and seasonal changes in the sky) #dok3
Learning Targets
  • I can describe that the sun appears brighter than other stars because it is closer to Earth. #dok1
  • I can identify data that shows differences in brightness between the sun and other stars. #dok1
  • I can represent data in graphs about length and direction of shadows, day and night, and seasonal star patterns. #dok2
  • I can identify and describe patterns in changes of shadows, day/night, and star appearance using graphical data. #dok2
  • I can support an argument using evidence that the sun looks brighter than other stars because it is much closer to Earth. #dok3
  • I can interpret graphical displays to explain how patterns of shadows and star appearances change throughout the year. #dok3
Big Ideas
  • The relative position of the sun and stars to Earth affects how bright they appear in the sky.
  • Patterns of daily and seasonal changes in shadows and star appearances provide evidence for understanding Earth's place in the universe.
Essential Questions
  • Why does the sun appear so much brighter than other stars in the sky?
  • How do the length and direction of shadows change during the day and across seasons?
  • What patterns can we discover by graphing daily and seasonal changes in the sky?
  • How does Earth's movement in space affect what we see in the night sky?
  • What evidence can we use to support ideas about Earth's position and movement in the universe?
