Baru sebulan Ocean Theme lepas tapi interest diri sendiri masih tinggi so this is just right. ^^
Gyres are large-scale, closed ocean flow patterns that result from wind forcing, buoyancy forcing, and the Coriolis acceleration. Since the Coriolis acceleration changes with latitude, gyre circulations are not symmetric and the flow on the western boundaries is stronger. Subtropical gyres are found in all the world’s oceans at mid-latitudes and they have a clock-wise circulation in the northern hemisphere and counter clock-wise circulation in the southern hemisphere. Subpolar gyres have the opposite circulation and are found poleward of subtropical gyres. Recirculation gyres are flows associated with major ocean currents and consists of water that recirculates in a closed pattern around most of the ocean basin. Large-scale recirculation gyres are associated with fast western boundary currents (worthington fig ). mesoscale recirculations are associated with meandering currents ( maybe sat image).
Tide: Ada dua gravitational pull. Moon and Sun, when in line, jadi maximum high tide and min low tide.
Rarely happened in CHina
The reason river water is fresh is also due to evaporation. When water evaporates from the ocean surface, the salts don’t evaporate with it. It’s this freshwater that eventually ends up in rivers. That’s why we end up with a totally different balance of salts in rivers and oceans.
5 cups whole wheat flour
3/4 to 1 cup cooking oil (we used coconut oil)
large plastic tub or trays
Seashells Toob or real seashells
Plastic crabs (I wouldn’t recommend real ones – grins)

Wax Resist Painting
Materials: Crayola crayons (NOT washable), blue watercolor paint, white construction paper.
Have students draw an ocean scene with crayons on white paper. Paint over the picture with a wash of blue watercolor.
Materials: water, salt, food coloring, white construction paper, paintbrushes
Mix 1/4 C. warm water with 6-t. salt and 3 drops of food coloring in each jar. Have students paint pictures with the water and salt mixture. The water will evaporate leaving colored “sand.”
