This computer-based learning module engages students in questions that scientists around the world are exploring about Earths climate. They gain an appreciation for how much is not known about the Earth and climate change. The module contains 5 activities; 1) Earths Changing Climates, 2) Interactions Within the Atmosphere, 3) Sources, Sinks, and Feedbacks, 4) Feedbacks of Ice and Clouds, and 5) Using Models to Make Predictions. Each activity provides information in simulations, text, video, or graphic format and the students enter answers to both open-ended and closed questions within the program. Once the students have completed an activity, they can print a report showing all the questions and their answers. The authors estimate the entire module should take 225 minutes.
