What is the impact of beach litter?
In this activity, students will construct a web of things that may increase or decrease as a result of beach litter. Student construct a life-size concept map to be to explain many potential impacts of beach litter and then discuss various interpretations of the possible debris impacts.

Ice Cover on the Great Lakes
NOAA’s Great Lakes Environmental Research Laboratory describes long-term fluctuations in ice coverage in the Great Lakes.
How do Greenhouse Gases Affect Heat Absorption?
Students build a model and simulate a portion of the greenhouse system using carbon dioxide, learning about the components of the greenhouse effect and the effect of carbon dioxide on the absorption of heat in the atmosphere.
How Did Rocks and Rivers Shape the Great Lakes?
The rocks in the Great Lakes Basin are of two main types: metamorphic/igneous and sedimentary. The metamorphic/igneous rocks formed long ago, when molten rock hardened and the heat changed other rocks nearby without melting them. This happened over one billion years ago. The sedimentary rocks in the Great Lakes Basin formed in an ocean that covered most of the basin beginning about 600 million years ago. Use maps skills to relate the hardness of rocks to topography and lake depth, describe the topography of the Great Lakes area, and relate the pre-glacial drainage system to the present size and position of the Great Lakes.
After completing this activity, each student will be able to:
- Relate the hardness of rocks to topography and lake depth.
- Describe the topography of the Great Lakes area.
- Relate the pre-glacial drainage system to the present size and position of the Great Lakes.
