Creating Ice Core Layers

The video tutorial, led by Jason Cervenak from the Bird Polar Research Center, demonstrates how to create fake ice cores for classroom use. It begins with an introduction to the significance of ice cores in climate research. The tutorial then lists the materials needed, such as a graduated cylinder, Pringles can, and instant coffee. Step-by-step instructions are provided for creating each layer of the ice core, including the addition of water, coffee, gravel, and fake insects. The video emphasizes the importance of freezing each layer before adding the next to prevent blending.

What is the primary purpose of ice cores in climate research?

• To measure the thickness of ice sheets

• To predict future climate changes

• To study the current weather patterns

• To understand the Earth's past climate

Which of the following is NOT a material needed to create a fake ice core?

• Extra large Pringles can

• Graduated cylinder

• Real insects

• Instant coffee

What is the first step in creating the ice core layers?

• Dissolving coffee in water

• Freezing the Pringles can

• Pouring 110 milliliters of water

• Adding gravel

Why is it important to freeze each layer solid before adding the next?

• To prevent the layers from blending

• To make the ice core more transparent

• To ensure the insects stay in place

• To speed up the freezing process

What is added to the second layer of the ice core?

• Gravel

• 110 milliliters of water

• 60 milliliters of water with dissolved coffee

• 60 milliliters of water

What additional material is added to the third layer of the ice core?

• Insects

• Food coloring

• More water

• Gravel

How should gravel be added to the ice core to avoid sticking to the sides?

• Pour it directly

• Use a spoon

• Mix it with water first

• Make a funnel with paper

At what point in the process are insects added to the ice core?

• In the first layer

• In a later layer

• In the second layer

• In the third layer

What is the recommended freezing time for each layer before adding the next?

• 48 hours

• 6 hours

• 1 hour

• 12 to 24 hours

What is the purpose of marking off each layer after pouring?

• To ensure the layers are even

• To prevent re-pouring the same layer

• To track the freezing time

• To label the materials used
