- There’s a copy of this document in your Science folder to guide your Science Fair Project.
- Porosity: The amount of space of the rocks for liquids to pass through
- Permeability: The rate of which the liquids pass through the pore space
- Water Table: The underground surface with soil or rock that are saturated with water.
Prior Knowledge about the Ocean
The information that are written on the board are:
- It’s salty. It’s saltwater.
- You can’t drink it.
- The ocean is about ~70 % of the Earth’s surface.
- There are many currents.
- There are many types of plants and animals.
- It’s always moving
- Sometimes, sewage and garbage is dumped into the ocean.
After discussing the prior knowledge, we talked about the basic knowledge of the ocean such as:
- The ocean is constantly moving.
- We get food - fish and shellfish - from the ocean.
- It is the part of the world that we know the least about.
- We know more about the surface of the moon than deepest parts of the ocean.
- It covers about ~70 % of the world.
- Sea creatures live in it.
- The tides are affected the moon.
- We use the ocean for transportation.
- Phytoplankton in the ocean also produce oxygen which we breathe
Then we learned about the six oceans which are:
- Southern (Antarctica)
Then we learned about the global circular surface ocean current
Then with clues given, we had to predict and draw the surface ocean currents. The clues were:
In this picture we can see where the wind is moving to.
In this picture, it is visible that this is happening in the Southern Hemisphere since it is moving counterclockwise.
