    Kansas Legislator Proposes Bill to Outlaw Sustainability Education

    A bill has been introduced in the Kansas legislature this week that would prohibit the promotion of sustainability. Here is a link to the one-page bill: http://www.kslegislature.org/li/b2013_14/measures/documents/hb2366_00_0000.pdf. See report on Bloomberg News.

    Earth's Center Is 1,000 Degrees Hotter Than Previously Thought, Synchrotron X-Ray Experiment Shows

    Scientists have determined the temperature near the Earth’s center to be 6000 degrees Celsius, 1000 degrees hotter than in a previous experiment run 20 years ago. These measurements confirm geophysical models that the temperature difference between the solid core and the mantle above, must be at least 1500 degrees to explain why the Earth has a magnetic field. For more information about this study, see the press release from the European Synchrotron Radiation Facility.

    Ocean Volcanic Rocks Contain Samples of Recycled Crust

    Scientists have long believed that lava erupted from certain oceanic volcanoes contains materials from the early Earth’s crust. But decisive evidence for this phenomenon has proven elusive. New research from a team including Carnegie’s Erik Hauri demonstrates that oceanic volcanic rocks contain samples of recycled crust dating back to the Archean era 2.5 billion years ago. Their work is published in Nature. Oceanic crust sinks into the Earth’s mantle at so-called subduction zones, where two plates come together. Much of what happens to the crust during this journey is unknown. Model-dependent studies for how long subducted material can exist in the mantle are uncertain and evidence of very old crust returning to Earth’s surface via upwellings of magma has not been found until now. For more information about these results, see the press release from the Carnegie Institution.

Definitions of Common Educational Terms


  • Scientific inquiry refers to the diverse ways in which scientists study the natural world and propose explanations based on the evidence derived from their work. Inquiry also refers to the activities of students in which they develop knowledge and understanding of scientific ideas, as well as an understanding of how scientists study the natural world.
  • Hands-on learning is learning through doing. The term is used commonly in science education and means that the students investigate a particular scientific phenomenon and develop understanding by actively participating in an activity or experiment.
  • Scientific knowledge refers to facts, concepts, principles, laws, theories, and models and can be acquired in many ways.
  • Scientific understanding encompasses the ability to use knowledge, and it entails the ability to distinguish between what is and what is not a scientific idea.
  • Scientific literacy is the knowledge and understanding of scientific concepts and processes required for personal decision making, participation in civic and cultural affairs, and economic productivity. Scientific literacy means that a person can ask, find, or determine answers to questions derived from curiosity about everyday experiences.
  • Content of school science is broadly defined to include specific capacities, understandings, and abilities in science.
  • Curriculum is the way content is delivered: It includes the structure, organization, balance, and presentation of the content in the classroom. Curricula often will integrate topics from different subject-matter areas--such as life and physical sciences
  • The National Science Education Standards, produced by the National Research Council in 1995, are goals for science achievement in K-12 education. They were the result of four years of work by twenty-two scientific and science education societies and over 18,000 individual contributors. States and districts within the United States have typically developed their own science standards based on the National Standards.
  • No Child Left Behind (also known as NCLB) attempts to improve performance of American K-12 schools by increasing the standards of accountability for states, school districts, and schools, as well as providing parents more flexibility in choosing which schools their children will attend. The law has drawn criticisms and lawsuits against the Bush administration by some school district and educational organizations that state that the law is flawed and under funded.
