Water Reservoirs and Scaled Models

The video tutorial guides students through an assignment on Earth's water reservoirs. It begins with an introduction to the task of predicting the largest water reservoirs, followed by a detailed explanation of what reservoirs are. The teacher then conducts a lab demonstration to compare students' predictions with actual data, highlighting the size of different reservoirs. Finally, a visual representation of Earth's water distribution is presented, scaled down to 1,000 milliliters, to help students understand the relative sizes of various water sources.

What is a reservoir?

• A place where water is stored underground

• A type of lake

• A method of water purification

• A supply or source of something

Which of the following is NOT an example of a reservoir?

• A reservoir of medical supplies

• A reservoir of food

• A reservoir of oil

• A reservoir of sunlight

What should you do after predicting the largest water reservoir?

• Discuss with a partner

• Fill out the prediction chart

• Submit your prediction online

• Write a report

Which reservoir holds the most water on Earth?

• Lakes

• Rivers

• Oceans

• Glaciers

How much water do lakes actually hold compared to oceans?

• More than oceans

• Lakes do not hold water

• Less than oceans

• The same as oceans

In the scaled-down model, how much water is represented by the oceans?

• 965.4 milliliters

• 500 milliliters

• 1000 milliliters

• 17.4 milliliters

What is the approximate amount of water in glaciers in the scaled model?

• Less than 1 milliliter

• 17.4 milliliters

• 500 milliliters

• 965.4 milliliters

Which reservoir has slightly more water than rivers in the scaled model?

• Glaciers

• Atmosphere

• Groundwater

• Lakes

What should you do after filling in the chart with the scaled model data?

• Discuss with classmates

• Reflect on the activity

• Watch the video again

• Submit the chart

What is the purpose of reflecting on the activity?

• To prepare for a test

• To understand Earth's reservoirs better

• To memorize the data

• To complete the assignment
