Scientists have associated the El Niño/Southern Oscillation (ENSO) phenomenon with extreme climate events such as flooding in California, droughts in Australia, fires in Indonesia, and increased hurricane activity in the Atlantic Ocean. Because most textbooks fail to adequately cover this important topic, an ENSO learning experience was developed that is directed toward middle level students. It teaches them about climate science and forecasting with an in-depth study of ENSO. This article focuses on the ENSO-related material located on the DECIDE website (see Resources), a resource developed by teachers at Texas A&M University and College Station Independent School District with funding from the National Oceanic and Atmospheric Administration (NOAA).
