Watch episode 4. If you are unable to view episode 4 in its entirety then students will need to watch the following segments to support their learning experience. As students watch each segment have them stop and answer each of the questions below in their science notebook. At the conclusion of all segments, encourage students to add to or modify their thinking.
- Minute 13:10 to 17:07
- Explain what’s happening to cause ice quakes.
- What is the ripple effect related to calving or breaking off of these large chunks of ice? What will happen in the end?
- Lesley Stahl said the amount of ice that melted in Greenland in 2012 was equivalent to Niagara Falls running into the ocean for 5 straight years. (Niagara Falls actually flows into Lake Erie and then onto Lake Ontario.) In one second the Niagara Falls spills 750,000 gallons of water. So how many gallons of water melted in 5 years? A little help – 5 years = 3.156 x 107 seconds
- Minute 23:39 to 25:20
- Explain the evidence Dr. Tedesco uses to help draw conclusions about what is happening in the arctic.
- In your science notebook, sketch and label Dr. Tedesco’s explanation of albedo and write a definition of albedo in your own words.
- Minute 37:41 to 40:03
- How did you take Aleqa Hammond’s interview? Surprised? Expected? Explain your response.
- Minute 43:23 to 47:22
- Explain what John Kerry sees as a solution to the environmental pushback we see here in the U.S.
