Ocean Currents and Their Effects

Mr. Gerrity from Porterville High School presents an online lab titled 'Ocean Activity Model'. The lab simulates ocean currents and their impact on regional climates. Students need tap water, a container, a coffee pot, ice, color dye, and a thermometer. The experiment involves setting up a model with hot and cold water to observe how ocean currents move. The lab demonstrates how warm water rises and cold water sinks, creating a conveyor belt effect. The session concludes with observations of color mixing and water movement.

What is the main objective of the ocean activity model lab?

• To create a model of ocean wildlife

• To study the chemical composition of ocean water

• To measure the temperature of ocean water

• To simulate ocean currents and their impact on climate

Which of the following is NOT a required material for the experiment?

• Tap water

• Sand

• Coffee pot

• Ice

What is the purpose of using color dye in the experiment?

• To change the water's temperature

• To visualize the movement of ocean currents

• To make the water more acidic

• To increase the water's density

What is the recommended temperature for the hot water in the experiment?

• 50 degrees

• 60 degrees

• 70 degrees

• 80 degrees

How does the sun affect ocean currents according to the experiment?

• It cools the water at the poles

• It warms the water at the equator

• It causes water to evaporate

• It changes the water's salinity

What happens to water as it moves toward the poles?

• It becomes more acidic

• It cools and sinks

• It evaporates

• It heats up

What is the term used to describe the continuous movement of ocean water?

• Tidal wave

• Conveyor belt

• Waterfall

• Cyclone

In the experiment, what is observed about the warm water?

• It moves through the top passage

• It mixes with the ice

• It stays at the bottom

• It evaporates quickly

What effect does the ice have on the water in the experiment?

• It changes the water's color

• It cools the water and causes it to move

• It causes the water to evaporate

• It heats the water

What is the final observation about the movement of water in the experiment?

• The water changes color completely

• The cold water rises to the top

• The warm water moves toward the cold

• The water remains still
