This activity is designed to introduce students to planetary geologic features and processes. First, students will use NASA satellite images to identify geologic surface features on the "Blue Marble" (Earth), and will explore the connection between... (View More) those features and the geologic processes that created them. Using that information, students will then compare and discuss similar features on images from other planets. Included are the following materials: teacher's guide (with reference and resource information), student's guide (with activity sheets), and multiple cards of planetary images. Note that the range of targeted grade levels is quite broad; however, explicit adaptations for younger students are highlighted throughout the teacher's guide. (View Less)

This activity explores how ancient Sun observers made use of natural and built structures to mark solar alignments observed at different times of the year, particularly around the solstices and equinoxes. In Part 1, the teacher prepares a horizon... (View More) table that represents the Earth’s horizon. In Part 2, students create functioning models of an existing ancient solar observatory or design their own observatory. In Part 3, students test their model using the horizon table and a flashlight as the Sun. The lesson includes discussion questions, background information about Maya astronomy, a checklist for science notebook write-ups, and a math extension activity that measures shadows. This activity is the seventh lesson in the Ancient Eyes Look to the Skies curriculum. (View Less)
