In this activity, students download historic temperature datasets and then graph and compare with different locations. As an extension, students can download and examine data sets for other sites to compare the variability of changes at different distinct locations, and it is at this stage where learning can be individualized and very meaningful.

This activity allows students to make El Nino in a container, but it might work better as a teacher demonstration. The introduction and information provided describe El Nino, its processes and its effects on weather elsewhere in the world.
