El Niño sure creates a stir when it comes around! Why not stir up your earth science class with this data analysis activity that examines the temperature and precipitation over the 2002-2003 water year. A tracking chart is provided...

Students explore parallel and series circuits. In this electrical circuit lesson, students  investigate the differences between series and parallel circuits.  Students observe the benefits and drawbacks of series and parallel...

Learners observe and discuss a demonstration of the El Niño effect, trade winds, and upwelling. They view and analyze the teacher using a blow dryer to replicate the El Niño winds on colored water and oil in a large tub.
