Bernoulli's Principle and the 1st Grade

As part of our study of air, the 1st grade did some experimentation with the effects of air pressure.  First, we tested just how much pressure we could apply to a wall when standing still, walking, and then running.  It's a lot harder to press hard on a wall when you are running alongside of it!  That's just like air pressure.  The faster the air is moving, the lower the pressure.  Next, we figured out how to blow up giant wind bags using that same concept. Them it was back to the classroom for more experimentation.  Watch for the results of all of our hard work at Science Night in April!
