Hurricane Activity

The majority of damage from hurricanes comes from heavy
winds. We watched a youtube video about hurricanes where
the wind blew the roof off of a house. Then we did our own
activity. We built a house out of index cards and then tested
their strength with level one winds (one straw). Seeing that
the house blew down, we reinforced it (with more tape). It
then withstood the level one winds but succumbed to level
two winds (two straws).
