Scientists study things by looking at them very carefully, by measuring them, and by doing experiments and tests.Scientists try to explain why things act the way they do, and predict what will happen.Greenland ice cores contain layers of wind-blown dust that correlate with cold, dry periods in the past, when cold deserts were scoured by wind.Radioactive elements, either of natural origin or created by nuclear testing, can be used to date the layers of ice.»Antarctica and Easter Island »The Noah Movie Runs Aground »Ark Movie Pre-Review »The Evolution of Eating »Why Doesn’t the Church Provide Answers?

Science makes models of nature, models of our universe, and medicine.

Science makes use of mathematics, and it makes observations and experiments.

Science produces accurate facts, scientific laws and theories. Scientific research uses hypotheses based on ideas or earlier knowledge. People who study and research science and try to find out everything about it are called scientists.

Since the ice forms from the incremental buildup of annual layers of snow, lower layers are older than upper, and an ice core contains ice formed over a range of years.

Cores are drilled with hand augers (for shallow holes) or powered drills; they can reach depths of over two miles (3.2 km), and contain ice up to 800,000 years old.
