Super Superior

imagesIn addition to the colorful trees, spending a day on Lake Superior was one of the highlights of my recent trip to Michigan. One definition for SUPERIOR is “greater in amount, number, or degree.” That perfectly describes record-setting Lake Superior.

Some super stats:

  • Largest freshwater lake in the world by surface area.
  • Third largest lake by volume (Lake Baikal in Siberia and Lake Tanganyika in East Africa contain more water).
  • Holds three quadrillion gallons—enough water to cover North and South America in one foot of water. It could hold all the water in the other Great Lakes, plus THREE MORE Lake Eries.

The Great Lakes make up 20 percent of the Earth’s available (not in the ice caps) surface fresh water and half of that water is stored by Lake Superior. Superior is the cleanest and clearest of the Great Lakes. Thanks to low amounts of nutrients, sediments, and organic material, you can see about eight feet under the water – great for exploring.

Inside: Creating the Great Lakes

pic.great_lakesGlaciers gouged out Lake Superior and the other four Great Lakes as a ice sheet moved across North America 2.5 million years ago. Give your students a kinesthetic experience by having them “become a glacier” slowly moving forward and then receding.

The following directions are from  How We Know What We Know About Our Changing Climate Teacher Guide:

  1. Pantomime several actions, such as eating a banana, reading a book, and ice skating on a pond. Ask your students to guess what you’re doing. Explain that you demonstrated human actions, and either pantomime or ask for volunteers to pantomime natural events, such as the sun rising, a flower opening, and a tree in autumn dropping its leaves (props are OK).
  2. Tell students that they’re now ready to pantomime a more complicated natural event—the life of a glacier. Begin by having students brainstorm adjectives that describe a glacier. Create a definition from their adjectives. [Definition: A glacier is a large, slow moving river of ice, formed from compacted layers of snow.] Explain that glacier ice is the largest reservoir of fresh water on Earth and is second only to the oceans as the largest reservoir of total water.
  3. Divide the class into three groups and assign each group to develop a pantomime that demonstrates one of the three phases in the life of a glacier: (1) Growing, (2) Moving, and (3) Retreating. Use the information Life of a Glacier. To avoid any injuries, you may want to establish some guidelines, such as “No climbing on another student’s back.” Encourage the use of props.
  4. Give groups time to develop and practice their pantomime. It’s best if groups can practice out of the view of  other groups.
  5. When all groups are ready, have them act out their pantomime while you read the information about each of the phases. Have students acknowledge each “performance” with enthusiastic applause!

Outside: Making a Waterscope

WaterscopeinStream_NWF_219x219An easy-to-make waterscope allows your students to get a look beneath the water’s surface—get directions from Susie Caldwell Rinehart, author of Eliza and the Dragonfly. Students can use their scopes at a lake, pond, creek, or even a big puddle.
