  • Lesson 1: To fix reference points that line up with true north in your classroom, on the school grounds and at home.
  • Lesson 2: To construct a Pointer Box to determine the locations of Polaris and the celestial equator at your latitude.
  • Lesson 3: To trace the path of the sun across the sky at its solstice and equinox positions. To observe where the sun rises and sets during different times of the year.
  • Lesson 4: To verify that the Sun Straw on the Pointer Box really tracks the apparent path of the sun across the sky.
  • Lesson 5: To construct a mini-planetarium in a baby food jar. To model the apparent motion of the sun and stars around our rotating earth.
  • Lesson 6: To model how the sun and stars move relative to a flat horizon. To compare this motion at different latitudes.
  • Lesson 7: To distinguish between the actual positions of stars in space and their apparent position on the celestial sphere.
  • Lesson 8: To plot star position on a polar graph in terms of sidereal time and declination. To use the resulting star map to predict star positions in the daytime sky.
  • Lesson 9: To estimate the apparent separation between stars in the Big Dipper. To observe polar constellations in the night sky.
  • Lesson 10: To develop a concrete understand of the quantity 'one million.' To appreciate the dramatic increases the result from an exponential expansion.
  • Lesson 11: To develop an understanding of astronomical distances within our solar system. To define the speed of light.
  • Lesson 12: To distinguish between actual star distances, measured in Light Years, and apparent star separations measured in degrees. To appreciate the vast magnitude of interstellar space.
  • Lesson 13: To draw the paths of the orbiting planets in our solar system to scale.
  • Lesson 14: To assemble a paper globe that maps the constellations. To compare this model of the celestial sphere of previous models.
  • Lesson 15: To cap the Sky Sphere with a Zodiac Ring that fixes the sun's ecliptic position among the constellations in terms of calendar date and sidereal time.
  • Lesson 16: To search out constellations in the night sky over the next few weeks and record them on a Sky Wheel.
  • Lesson 17: To draw the sizes of the sun and the planets to scale on notebook paper.
  • Lesson 18: To model the sizes of the planets and their distances from the sun in the same scale model. To appreciate that our solar system is a very empty place.
  • Lesson 19: To track the planets and the moon on the ecliptic circle. To visually identify at least one planet and document its shifting position among the background stars.
  • Lesson 20: To model the Milky Way Galaxy and understand its orientation in our night sky. To appreciate the vastness of intergalactic space.
Watch for new developments on the re-, re-, re-classification of Pluto. Formerly a planet, it has been redefined several times in the past few years. Various groups in the the science community have called it a minor planet, a plutoid, and finally (perhaps), a dwarf planet. A large segment of the general public would prefer that it keep its status as a small planet. As of early 2009, the debate may still be in orbit.
Keep a few constructed instruments available in a corner workstation for students who finish tests early, or for constructive activity on rainy days. For example, students might use the mini-planetarium in a jar to predict the rising and setting of constellations that evening, or on a specific date, like a birthday.
We encourage improvisation - it's one of the main goals of our hands-on approach! You and your students might invent a simpler, sturdier or more accurate system; might ask a better question; might design a better extension. Hooray for ingenuity! When this occurs, we'd love to hear about it and share it with other educators.
