In this activity, students will model the geometry of solar eclipses using quarters to represent the Sun and Moon (not to scale).
Guided by the 5E model, this lesson allows students to work together to uncover how changes in sea ice extent in the Arctic and Antarctic regions are connected to Earth’s energy budget.
The Solar Eclipse Implementation Sequence provides a series of lesson plans for students to learn about solar eclipses.
This USGS activity leads students to an understanding of what remote sensing means and how researchers use it to study changes to the Earth’s surface, such as deforestation.
