In this activity, students learn about the motion of the Sun in relation to the Earth, and how geographic directions are defined. Students use a tetherball pole (or an alternative) as a gnomon and the shadow the Sun casts to determine the exact... (View More)

This is a lesson that uses the study of sunspots to show how a scientific theory develops and how current technology might be used to support it. Learners will use E.W. Maunder's theory regarding the correlation between the numbers of sunspots and... (View More)

This is a lesson about Saturn. Learners will listen to a read-aloud of the history of Saturn discoveries. Next, they learn two reading comprehension strategies (visualizing and wondering) that they can use to become more powerful readers of... (View More)
