Global warming is the subject of this two-disk set, in the series Classroom Encounters with Global Change Scientists. The program addresses the possibility of extreme climate change. The first disk allows viewers to see the entire presentation, whereas the second disk offers 28 "breaks" for illustrations, simple demonstrations and experiments, and philosophical issues related to research. The entire package supports inquiry into what humans can do to prevent extreme climate change.
Paul Hoffman, professor and field geologist at Harvard University, shares his passion and knowledge with students in the lecture portion of the presentation and responds to questions in the inquiry sessions. His lecture fits well with the ability level of the students, as he explains the phenomenon of climate change from past to present and the potential for even greater change in the future. The excitement of the classroom environment is supported by objects, charts, and tools that enhance the value of this encounter between students and expert.
This production is the result of a collaboration among amateurs (students who developed the original illustrations and music) and experts who finalized the package. In chapter stops there are overview questions that set the stage for learning and allow students to master the lesson content. As Snowball Earth provides both chapter and full play options, teachers can use this product in the manner that best suits their teaching style and the learning style of their students.
