Density & Buoyancy -- TeachPower.net Lesson

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 body and organ systems that provide support and movement for our body like muscles and bone. 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 cwarner@teachpower.net 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!

populop... Your reply is rather short. Do you mean the video is short? In that case if you read the description, it is short because it is a PREview of the full presentation that you can purchase at my teacher's resource website. Secondly, if you notice in the picture when the sub is completely full it does sink. That is how buoyancy works on a submarine.
