A quick survey I gave my 7th grade science students related to severe weather. They gather data from 10 people about weather awareness and use online graphing tools to graph their results and analyze the resulting data. When you go over results with your class, the answer to #3 is floods. They will probably find most people say tornadoes or hurricanes. But, floods are by far the #1 deadliest and costliest weather phenomenon in the US.We used this activity to incorporate math into science class.
