Ways to experiment Adhesion, Cohesion, Surface tension, Specific heat, and Density
River basins in NC:
A river basin is the portion of land drained by a river and its tributaries.
North Carolina had 17 river basins.
I will describe one of the river basins:
-The Catawba River Basin is made up of eleven lakes, the river between and the tributaries of streams, creeks and flows into them. Click on a section of the map below for more information about the lake or area you are interested in.
- Adhesion- Water's ability to stick to different atoms. You can test this by dropping a drop of water on a leave and seeing how long it stays there.
- Cohesion- Water's ability to stick to like atoms. You can test this by putting two drops of water on a countertop add seeing if they merge.
- Surface Tension- Water will stick together. You can test this by placing a penny on a glass of water and seeing if it floats.
- Specific Heat- Heat required to raise a unit of a substance by 1 degree Celsius. To test this place a pot of water on an oven with a thermometer in it and see when the temperature rises.
- Density- Amount of a solute in water. To test this you pour salt in a glass of heated water and measure how much salt was absorbed

Why upwelling is necessary for ocean life and fisheries:
One reason is because in a marine ecosystem the plankton live in the first zone and rely on upwelling. Upwelling is where nutrients from the bottom layer are brought up to the top layer. Without the upwelling there would be no plankton and no way for organisms under water to get nutrients from the plankton.
