we were a little late getting out of the apartment for chanda's world geography presentation with her homeschool class. however, a few others were late too, so it worked out.
silvie went first and presented her report on earth.
then chanda presented water, which she shared with another classmate. she spoke about the major wind belts which go all the way around the globe: the trade winds, the westerlies and the polar easterlies. the only ocean current that goes completely around the world is the antarctic circumpolar current, also known as the west wind drift.
singing a native american song they had learned:
the river is flowing
flowing and growing
the river is flowing
back to the sea
mother carry me
a child i'll always be
mother carry me
back to the sea.
the river is flowing
flowing and growing
the river is flowing
back to the sea
mother carry me
a child i'll always be
mother carry me
back to the sea.
thea continued the presentation on water with information about the mariana trench.
chanda draw a diagram of the main ocean currents which are the gyres (top right paper). there are five main gyres: the north and south pacific, the north and south atlantic, and the indian. these currents travel along with the winds until they hit a continent when they are forced to turn. due to the coriolis effect they turn clockwise in the northern hemisphere and counterclockwise in the southern hemiosphere. after running along the shore of the continent, they hook back up with a current that is flowing back the way it had come, forming a circle.
the coriolis effect is a phenomenon that causes fluids, like water and air, to curve as they travel across or above earth's surface. because the earth is spinning around its axis from west to east and because it is a sphere and wider at its middle, points on the equator are spinning faster than points on the poles. winds that are moving from equator to pole are deflected to the right in the northern hemisphere and deflected to the left in the southern hemisphere.

their rendition of the geographical fugue, which i thought was very good!
next, austin presented his report on fire.
he went into a detailed account of how fire has kept us warm through the ages from the paleolithic people to our present day use of coal, geothermal, nuclear, wind and solar power.
the main forms of energy on earth are movement, light and heat.
svetlana's presentation of air included a picture of one of her favorite paintings by arkhip kundji, a russian landscape painter of greek descent. he lived from 1842 to 1910. i find this painting incredibly beautiful and present day feeling, not from the turn of the 20th century.
a diagram of the wind belts.
