|Investigation 1.4: A Case StudySea Ice Research
Upon completion of this activity, students will:
- Know that the suns energy arrives as light with a range
of wavelengths, consisting of visible light, infrared radiation
(heat), and ultraviolet radiation. That light interacts with matter
by transmission (including refraction), absorption or scattering
- Know that energy, enters an ecosystem as sunlight. It is transferred
by producers into chemical energy through photosynthesis. That
energy then passes from organism to organism in food webs.
- Define, What is sea ice? and communicate its value/role
in climate, ecosystems and in research.
- Recognize how the history of the earths climate is studied
via ice core research and that technology used to gather data
enhances accuracy and allows for analyzing and quantifying results.
- Use the tools, including and techniques, of scientific inquiry,
to gather, analyze and interpret data including, graphing, reasoning,
drawing conclusions and communicating findings.
- Think critically and logically to make relationships between
evidence and explanation, as well as communicate procedures and
- Analyze and understand that water, which covers the majority
of the earth's surface, circulates through the crust, oceans,
and atmosphere in what is known as the "water cycle."
Water evaporates from the earth's surface, rises and cools as
it moves to higher elevations, condenses as rain or snow, and
falls to the surface where it collects in lakes, oceans, soil,
and in rocks underground.
- Understand that science and technology are reciprocal. Science
helps drive technology, as it addresses questions that demand
more sophisticated instruments and provides principles for better
instrumentation and technique. Technology is essential to science,
because it provides instruments and techniques that enable observations
of objects and phenomena that are otherwise unobservable due to
factors such as quantity, distance, location, size, and speed.
Technology also provides tools for investigations, inquiry, and
