5th Grade Hurricane Hypothesis
Fifth graders at Varina Elementary have been learning about the scientific method: forming a hypothesis, collecting data, taking measurements, graphing information, and analyzing the results (SOL5.1). Since Virginia is currently facing the threat of Hurricane Florence, and since the 5th graders need to review weather (SOL4.6), we decided to research hurricanes using the scientific method. First, I showed them some photos of past hurricanes and identified the eye of the hurricane. If the “eye” is the center, then the “eyelid” can be the area near the eye, and the “eyebrow” can be a bit further out. What part of the hurricane has the strongest winds? We made a copy of this spreadsheet, and I asked the students to write their hypothesis in the purple box. For example: If the distance from the eye increases, the windspeed will increase (or decrease). Now it was time to make some measurements and collect data. We went to Windy and Earth which show live storms on the Earth. You can click anywhere in the storm to get the windspeed (you may need to go to settings to change the units to mph). We used Accuweather or the National Hurricane Center to get the names of the hurricanes. The students could measure the winds in any hurricane they wanted, and I pointed out that the more data they collect, the more reliable their conclusions will be. They recorded the information in their spreadsheet, including the name of the hurricane and the windspeed measured at the eye, eyelid, eyebrow, and maximum (found by just searching around the storm for the biggest number). Finally, I showed them how to graph the data and customize the colors. We analyzed the results to confirm or revise our hypothesis. Most of us discovered that the strongest winds were in the eyebrow area, so as the distance from the eye increased, the windspeed increased. You can take a look at some student samples here. UPDATE: Schools closed the next day, 9/14, due to Hurricane Florence, and on 9/17 we had tornados!
