Daytime Sky

Summary

Students will investigate the Sun and Moon directly and indirectly through shadows and telescopes, build a sundial to tell time, craft a Moon model to experience the scale of Earth-Moon distance and the origin of moon phases, and practice recording observations in a booklet.

Objectives [+ relevant WI standards for science]

  1. Study the Sun

    1. Observe that shadows cast by the Sun point opposite the Sun’s current position and that shadow motion can be used to infer the Sun’s motion
      [SCI.ESS1.A.1, SCI.ESS1.B.5, SCI.SEP3.A.K-2, SCI.SEP3.A.3-5]
    2. Make a horizontal sundial from cardstock and use the shadow caster (gnomon) of the sundial to tell local time
      [SCI.ESS1.A.1, SCI.ESS1.B.5, SCI.SEP6.K-2, SCI.SEP6.B.3-5]
    3. Observe the Sun through two telescopes using different filters: look for the apparent texture of the Sun and any spots
      [SCI.ESS1.A.1, SCI.ESS1.B.5, SCI.SEP3.A.K-2, SCI.SEP3.A.3-5]
  2. Study the Moon

    1. Observe that the Moon can be visible even during the day and that it has a lit shape on the side facing the Sun
      [SCI.ESS1.A.1, SCI.ESS1.B.5, SCI.SEP3.A.K-2, SCI.SEP3.A.3-5]
    2. Make an air-dry clay model of the Moon scaled to a foot-size (standard desktop globe) Earth and experience the scaled Earth-Moon distance
      [SCI.ESS1.A.1 & SCI.ESS1.B.5]
    3. Use a source light to observe the phases of the Moon caused by relative Earth-Sun-Moon arrangement
      [SCI.ESS1.A.1, SCI.ESS1.B.5, SCI.SEP6.A.K-2, SCI.SEP6.A.3-5]
    4. Observe the Moon through a telescope and learn the names of some of the prominent features on the Moon (maria & craters)
      [SCI.ESS1.A.1]
  3. Record observations

    1. Make a sketchbook from letter-size paper to record Sun and Moon observations
      [SCI.SEP8.A.K-2, SCI. SEP8.A.3-5]
