Scientists use bathymetry to understand the ocean floor. This lesson is a basic introduction to bathymetry using salad trays to help students understand how bathymetric maps work.
Objectives
1. Students will be able to identify the advantages to using a bathymetric map.
2. Students will be able to transform a bathymetric map into a three-dimensional model.
3. Using just
One of the first things to understand about the Antarctic ecosystem is what kinds of animals actually live there. This lesson provides a basic introduction to important Antarctic wildlife and how they interact with each other.
Objectives
Students will be able to create a food web of the Antarctic ecosystem.
This one hour presentation by Dr. Al Werner is a professional development opportunity for educators to learn more about earth and geoscience research in Svalbard, Norway. Some noticeable technical issues are resolved a few minutes into the presentation.
This is a one hour PolarConnect event with PolarTREC teacher Amber Lancaster and her research team aboard the RV Nathaniel B Palmer. They are studying the collapse of the Larson B Ice Shelf in Antarctica and its impact on the ecosystem of the Weddell Sea. Note: Due to satellite phone connection there are a few moments of dropped audio, the
Students will use marshmallows to simulate toxins in the environment. Concentrations of these toxins will be modeled and calculated as they bioaccumulate up the food chain. Methylmercury and POPs are substances that bioaccumulate in the Arctic food chain. OASIS scientists studied these in Barrow, Alaska.
