How Can Disappearances Within the Triangle Be Explained?

Investigating multiple hypotheses, students discuss the values of using several data types and sources to
solve a science problem, demonstrate how bathymetric charts are used and constructed, demonstrate how weather information is mapped and interpreted, and explain how scientists use multiple working
hypotheses to solve complex problems.

Estuary Values

Activity A:  What is the ecological role of an estuary?

In this investigation, students use various sets of data to examine some of the characteristics of the estuary at Old Woman Creek,near Huron, Ohio. Students learn about the methods used by ecologists to sample populations of plant and animal life in aquatic ecosystems, the living communities that are found in different depths of water in an estuary, and how plant communities are important to animal life in an estuary.

Activity B: How do estuaries impact nutrients entering a lake?

Students analyze a map and data to learn how estuaries affect nutrient levels as water enters a lake.
They make predictions about how the effects of climate change might affect an estuary’s ability to improve water quality and function properly.

Snowmaking: Great Lakes Style

Students living near the Great Lakes often feel the chill of lake-effect snowstorms. Students who have been introduced to weather basics can become familiar with the lakes’ effect on winter storms through this mapping exercise. This activity involving map interpretation skills compliments a weather and climate unit.

How do the Great Lakes modify the growing season?

Using agricultural product and frost maps and an infrared satellite image, students develop a hypothesis about the effect of the lakes on growing seasons and then create a model to test the hypothesis.

What happens to heat energy reaching the Great Lakes?

Even as far back as the “log cabin days,” people knew that water absorbs a great deal of heat energy and can in turn release this heat. Pioneers would prevent foods from freezing on cold nights by placing a large container of water in the room. Can you think of why this might work? Conduct an investigation to explore how bodies of water can affect the surrounding areas. Learn how soil and water differ in their ability to absorb and release heat energy and how this difference in heat absorbed or released affects the atmosphere immediately above the land and immediately above the water.

How is coastal temperature influenced by the Great Lakes and the ocean?

The ocean is a major influence on weather and climate. Use a combination of laboratory investigation, map study, and graphing to learn how large bodies of water can serve as a heat source or sink at different times and how proximity to water moderates climate along the coast.

What is the Great Lakes Triangle?

Former aviator Jay Gourley has written a book called The Great Lakes Triangle (1977), which claims that the Great Lakes account for more unexplained disappearances per unit area than the Bermuda Triangle. This is no small comparison, considering that the Bermuda Triangle is 16 times larger than the Great Lakes area.
When you have completed this activity you will be able to:
  • Demonstrate an ability to perceive patterns in a set of data.
  • Explain how scientific habits of mind should include the seeking of logical explanations for “mysterious” happenings.
