  6. History Learning from the Past

  7. Oceanography and Marine Biology began as a necessity – not a science!

  8. Minoans and Phoenicians used the Mediterranean for trade.

  9. Greeks calculated the Earth’s size, shape and latitude lines. • Eratosthenes' Calculation of Earth's Circumference • By comparing the shadow of the sun at Summer Solstice noon at Alexandria and Syrene, and knowing the distance between the two, he calculated the circumference of the earth to be 250,000 stadia (about 24,662 miles).

  10. Vikings, led by Leif Erikson, colonized Iceland in 700 A.D. and North America by 100 A.D.
