This is a short NASA video on the water cycle. The video shows the importance of the water cycle to nearly every natural process on Earth and illustrates how tightly coupled the water cycle is to climate.

Students observe the process of evaporation, make comparisons about the process, then construct a diagram and use it to describe the process of evaporation.

This demonstration shows how water absorbs more heat than air. The corollary that is made is that the oceans are absorbing a lot of the heat related to climate change. The video tutorial shows an engaging demonstration that teachers can do live in their classrooms as part of a larger lesson/discussion about global warming. The video itself also includes an animation of how greenhouse gases contribute to global warming and concludes by mentioning simple solutions for students.
