Shadow Play or, in Spanish, Juego de la Sombra—pdf	None	Make shadows using objects of various shapes (cone, ball, block). Show how the shadow changes when the light is in a different position. Draw shadows at school several times throughout the day (as in Teacher Guide).
Constellation Games	None	Make own constellation based on another real (e.g. Orion or Leo) pattern. Make a story for your constellation.
Planet Tours	Learn the names of planets in the solar system.	Distance scale of solar system—pdf or, in Spanish, Modelos a escala del Sistema Solar—pdf Modeling the night sky from the Teacher Guide or, in Spanish, Modelos del cielo nocturno —pdf Solar System Science from the Teacher Guide or, in Spanish, Ciencia del sistema solar —pdf
Modeling the Night Sky or, in Spanish, Modelos del cielo nocturno —pdf	Learn the names of planets in the solar system.	Distance scale of solar system—pdf or, in Spanish, Modelos a escala del Sistema Solar—pdf Finding locations of moon and planets on a monthly star chart, noting position of ecliptic.
Solar System Science or, in Spanish, Ciencia del sistema solar —pdf	Learn the names of planets in the solar system.	Distance scale of solar system—pdf or, in Spanish, Modelos a escala del Sistema Solar—pdf Modeling the night sky from the Teacher Guide or, in Spanish, Modelos del cielo nocturno —pdf
Equatorial Sundial or, in Spanish, Reloj Solar Ecuatorial —pdf Pattern template pdf	Make a plot of sunrise and sunset times for your locations for several dates before your trip (one data set per week for several weeks is better than many points for one week). Data can often be found in local newspapers, or at: US Naval Observatory StarDate	Make a plot of sunrise and sunset times for your location over a period of several months. Predict the future shape of the curve. Use the sundial once a month over several months, recording the time shown at clock noon. Use the SUTG to show why the clock time is not exactly the same as the sundial time everyday.
Reflection	None	Optics and light
Telescope Technology	Reflection (REQUIRED)	more Telescope Technology activities
Scale Models—pdf or, in Spanish, Haciendo Modelos a Escala —pdf	Know how to measure with a metric ruler.	Distance scale of solar system—pdf or, in Spanish, Modelos a escala del Sistema Solar—pdf Extend by making a similar scale model for Jupiter and its four largest moons, or Mars and its two moons.
Spectroscope or, in Spanish, Espectroscopio —pdf	Demonstrate flame spectra in the classroom.	For middle/high school, Colors of Stars—pdf or, in Spanish, Estrellas—pdf For high school, other activities from the spectroscopy series
Star Maps	Learn to point north, south, east and west.	Use your star maps and/or planisphere to locate stars in the night sky. Predict what stars will be high overhead on each student's birthday at 9 PM. Pick out a constellation and make up a new object to fit its star pattern; make up a story about this constellation.
