    Irish Chronicles Document Links Between Volcanoes and Weather

    A study of over 40,000 written entries in Irish Annals and ice core measurements shows a strong correlation between the occurrence of volcanic eruptions and extreme cold weather in Ireland over a 1200 year period. Data analyzed in this study cover the period from 431 to 1649, during which time up to 48 volcanic eruptions are identified in Greenland ice core records through deposition of volcanic sulfate in annual layers of ice. You can find the study (open access), published on 6 June 2013 in IOP Publishing's journal Environmental Research Letters, at http://iopscience.iop.org/1748-9326/8/2/024035/article.

    EF-5 Tornado in El Reno, Oklahoma Widest Ever Recorded in US

    The EF-5 tornado that hit El Reno, Oklahoma on May 31st was the widest ever recorded in the US, according to the National Weather Service in Norman Oklahoma. The tornado, which remained on the ground for 40 minutes and reached 2.6 miles across (4.2 km), took the lives of 18 people including storm chasers Tim Samaras, Paul Samaras and Carl Young.

    Atmospheric CO2 Level Tops 400 ppm

    During the week of May 13th, the CO2 level at the Mauna Loa Observatory in Hawaii topped 400 ppm repeatedly. Daily levels of CO2 can vary due to weather, and there are seasonal trends as well. The level of atmospheric greenhouse gases continues to increase, now over 120 ppm since the Industrial Revolution began. For more on the Keeling Curve, see http://keelingcurve.ucsd.edu/.

Getting to Know a School

Below are some questions that you might ask the teacher when setting up a classroom visit in order to get to know what the school is like and how the students are typically exposed to new ideas and information in science class. This can help you to format your class visit to suit the audience.

  • How many students are in the class?
  • Could you describe what students do during a typical science class?
  • Are students currently engaged in science projects? If so, what types? Did they develop the project ideas themselves?
  • Are students accustomed to lecture-style presentations? If so, what length works best?
  • Are students accustomed to hands-on learning experiences in science class?
  • Do students usually work in groups or on their own during science class?
  • Is your science curriculum integrated with other subjects?

Different Types of Schools

The information about various K-12 schools in the United States below is intended to provide a brief overview of various types of schools that might be interested in having a scientist come for a classroom visit.

  • Elementary schools: generally grades K-5 (ages 5-11). Usually, the same teacher is responsible for teaching all subjects except physical education, and occasionally music and/or art.
  • Middle Schools: generally grades 6-8 (ages 11-14), but can exclude 6th grade and may include 9th grade. Larger middle schools are often organized into teams of 100 or more students and four teachers (math, English, science, and social studies). The science teacher holds several classes each day for groups of these students. Subjects taught in middle school science classes vary but typical subjects include Earth science, biology, and physical science.
  • High Schools: generally grades 9-12 (ages 14-18). In some cases it includes grades 8, or excludes grade 9. In larger high schools with several science teachers, each teaches a particular branch of science (such as biology, chemistry, Earth science, and physics), and likely teaches several classes a day of the same subject, and potentially an advanced class as well. In smaller high schools, the science teacher is often responsible for teaching all science subjects.
  • Charter schools: innovative public schools started by parents, teachers, community organizations, and companies. Charter schools often vary in teaching methods and focus. For more information: U.S. Charter Schools Organization
  • Magnet Schools: highly competitive public schools that tend to have specialized programs in subjects such as art or science, for example.
  • Montessori schools: students engage in spontaneous, meaningful activities under the guidance of educators trained in the Montessori philosophy. The students progress at their own pace, according to their own capabilities. For more information: International Montessori Council
  • Waldorf schools: based on a developmental approach that addresses the needs of the growing child and maturing adolescent, to educate the whole child. For more information: Association of Waldorf Schools of North America
  • Private schools: there are a large variety of private schools including secular (non-religious), religious schools, and schools with different teaching philosophies such as expeditionary learning schools. For more information: National Association of Independent Schools
