Week 11: Ice Shelf

Week Eleven: Ice Sheets
Welcome to Planet "Ocean"
Weeks 10, 11, and 12 make up a three-week cycle about ice sheets. Currently, you are in the Event Study week of the cycle.

This week you and your Event Team will build on the sphere to sphere interactions you identified last week to synthesize them into causal chains or causal matrices. You will use the resources listed under Readings, discuss your ideas in the Classroom Event Study Space, then submit your team’s work to the portfolio for a grade.

Assignments:

Team: (by midnight Sunday)

Read about ice sheets.
Review the Event Study Goal and Rubric.
Serve as a "Sphere Expert" to your Event Team.
Read your teammates' summaries about the other individual sphere effects.
Identify intersecting and overlapping effects in your discussion in Event Space in the Classroom. Refer to the Week 3: An Example of an ESS Analysis reading if you would like to review causal relationships.

Submit to the Portfolio in the Classroom your team's most accurate analysis of the Earth Systems interactions with reasoning and support.

Suggested Activities for Your Students

Comparison of Snow Cover on Various Continents. Students will use the Live Access Server (LAS) to form maps and a numerical text file of snow cover for each continent on a particular date. They will analyze the data for each map and corresponding text file to determine an estimate of snow cover for each continent. http://mynasadata.larc.nasa.gov/L3_Scearce.html

Students determine the direction and speed of surface ocean currents. NASA's Earth Science Enterprise Education CD-ROM. http://eospso.gsfc.nasa.gov/eos_homepage/for_educators/cd_rom/supplement.php

Have your students respond to the following statements: "The ocean can provide a good dumping ground for trash, radioactive wastes, or anything else people don't want to clutter the ground up with. Besides, there is all that ocean life to decompose things. So it's better to dump our wastes in the ocean."

You will want to locate other resources locally and on the Internet to supplement these. Post the resources you find in Resource Space in the Classroom.

Featured Data Connection

MY NASA DATA is an effort to develop microsets of Earth science data that are interesting and useful for, K-12 education. The datasets can be used with existing curriculum and enable students to practice math skills using real measurements of Earth system variables and processes.

MY NASA DATA microsets are created using data from NASA Earth science satellite missions and provide information on the atmosphere, ocean and land surface. Data is easily-accessible online along with lesson plans, computer tools and an Earth science glossary. You can link to the MY NASA DATA Live Access Server (LAS) where you can select items (microsets of data) from the menu (list of datasets) using descriptions (parameters and time frames) of the items.

The LAS software allows access to scientific data referenced by latitude, longitude, and time. This is referred to as geo-referenced data. LAS can:

show visualizations (color plots and graphs) of the data as requested
provide subsets of the specific parameters in a choice of file formats (e.g., as an excel file)
present the numerical data collected

Opportunity for teachers to publish - Have you developed an original lesson plan using MY NASA DATA that worked well in your classroom? Please submit these lessons for review and possible publication on the MY NASA DATA website. Submit your original lessons to: essea@strategies.org . Be sure to include your name, email and phone number.
