4th Grade Videos

Fourth grade has been very busy the last two weeks conducting investigations about the properties of air:  Air has weight, air expands when heated, air is a real substance, etc.  We studied Bernoulli Principle too and learned that without this concept, flight would not be possible.  Several of our experiments showed how high and low pressure were affected when a fast-moving stream of air was present.  See our video for more details.  Next week:  Newton's Laws!
