At this time of the year here in New England we are in our winter months. As the temperatures hover below freezing, we do all we can to keep warm.
The temperature of the oceans, the air, and also the wind patterns of the planet all create climate. In the Oak Meadow 7th grade science curriculum you study about climate, weather patterns, and global winds. You learn the relationship between air masses and weather. You become a meteorologist! Collecting weather data is one job of a meteorologist, so students using the curriculum set up their own weather station, keep records over a 5 day period, and report their data. Looking at the past data and the present data allows meteorologists to predict the weather of the future.
Today some scientists are collecting data about the Arctic sea and the Antarctic sea. Scientists at the National Snow and Ice Data Center study the CRYOSPHERE, or more simply, they study the cold places on our planet. They study glaciers, snow, sea ice and specifically the areas around the North and South poles. In their studies of these areas, scientists have recorded warmer temperatures of the seas and the air. Those records provide data for the scientists to measure how much sea ice is disappearing. Just as 7th grade students record their own weather data and make predictions, these scientists gather data to report the impact the state of the cryosphere has on the planet. That means that they are able to report and predict weather patterns on the Earth. With warmer temperatures of water and air recorded, scientists are able to warn us of future climatic changes.
In the Oak Meadow science curriculum, you learn that ozone depletion, the thinning of the stratospheric ozone, contributes to global warming.
“How much can a single person affect Earth’s changing climate? According to researchers in the United States and Germany, 3 square meters of summer sea ice disappear in the Arctic for every metric ton of carbon dioxide (CO2) that a person directly or indirectly produces. How can one person produce 1 metric ton of CO2? That’s about a roundtrip flight from New York to Europe per passenger. Or, a 4,000-kilometer car ride.” https://nsidc.org/news/newsroom/us-and-german-researchers-calculate-individual-contribution-climate-change
The Oak Meadow science curriculum across the grades has assignments in which students consider how to limit, or reduce, their impact on the ozone, and how the ozone can be preserved. If you are a student, or family, looking for suggestions on how to reduce your impact, read this.
