Powerpoint presentation covering floods, hurricane, tornados, tsunamis, lightning, volcanos and earthquakes.
Each slide is simple and contains only a 2-3 minute National Geographic 101 video. Teacher could discuss with the class what they know about each topic before they play the video and then after each video discuss what they now know.
Worksheets are good for data gathering while each video is playing or during discussion.
I do not own the National Geographic videos, I have simply obtained them on YouTube and compiled them altogether in the one place.
