On November 2, Tom Wahle of Techsploration presented the Science of Weather show to Fifth Grade (funded courtesy of HOP). First, he demonstrated that air takes up space, has weight and that it moves from high pressure to low pressure. Ask your student how he did these experiments! He talked about weather fronts, hurricanes, and tornadoes. Using a Van de Graff generator, Mr. Wahle demonstrated the concepts of electricity and illustrated how lightning bolts are formed.
