http://www.teachpower.net Preview of one of 140+ Powerpoint presentations that I use in my middle school science class that you can also find on my teacher resource website. This presentation covers information on the basic details and characteristics of Earth's atmosphere, including air pressure and heat dispersal. It follows current science curriculum for both middle and high schools. For a nominal fee you can get this presentation and 140 other presentations at my teacher resource website Teach Power.net. Stay tuned to teachpower.net as I have much more resources planned to help us teachers around the world accomplish our task. If you don't see a presentation lesson [be it science or not] that suites your needs then please email me firstname.lastname@example.org and I will be glad to create a custom presentation for any subject for you. **NOTE: THIS VIDEO IS JUST A PREVIEW OF THE FULL POWERPOINT LESSON. THE SPEED AT WHICH IT SHOWS IS FOR TIME PURPOSES ONLY! THE LESSON CAN BE PRESENTED AT YOUR PACE WITH MOUSE CLICKS. ENJOY!
