Productive Oceans and Land

• Class Activity
• A. Cleary

2
The Land

• Apple is cut from top to bottom in 4 equal pieces
• 3 represent the Ocean and 1 represents the Land
• Divide your circle to represent this. Label 3
  pieces The Ocean and 1 piece The Land

The Land

• Cut the 1 piece of apple (the land) into two
  equal pieces from top to bottom.
• 1 piece is land that is too hot, too dry, too
  wet, too cold, too high to live on.
• On your circle divide your Land in half. Label
  one piece by drawing a human with an X through it
  and the other with a human on it, call this
  habitable land.

The Land

• Now take the Habitable Land piece and divide it
  into 4 equal pieces, cutting from top to bottom.
  One of these pieces represent Productive Land
• On the circle divide the Habitable Land into 4
  equal pieces.
• Color one of these pieces and label it All Our
  Food

The Land

• Take the Productive Land Piece and cut off the
  thinnest slice you can.
• This represent 3/100 of 1 of the earths
  surface. This is our Drinkable Water
• On the circle represent the Drinkable Water
  with a dot. Label this on the circle

6
The Ocean

• Take 1 of the 3 pieces representing the Ocean and
  cut it in half from top to bottom. One of these
  pieces represents Productive Ocean
• On the circle cut one ocean piece in half and on
  1 piece label it Productive Ocean and draw a
  fish on this piece

7
The Ocean

• Cut the Productive Ocean piece into four equal
  parts form top to bottom. These represent the
  four major up welling zones in the ocean.
• On the circle divide the Productive Ocean into
  four equal parts, color 1 of these parts and
  label it Up welling off North America

8
The Ocean

• From an up welling piece cut off the thinnest
  slice possible. This slice represents 1/100 of 1
  of the earth surface. This is the Photic Zone
  the top 300 feet of the ocean which light can
  penetrate.
• Represent the Photic Zone with a dot on the up
  welling zone in North America. Label it.

Productive Ocean and Land Resources

• Look at the two tiny slices of apple. One
  represents the resources necessary for life on
  land and the other represents the resource
  necessary for life in the ocean.
• How are these two areas being impacted or
  affected by humans?
