Contribute an Activity

From the materials that you provide below, we will create a web page describing your contribution to the Teaching Geochemistry Activities and Assignments Collection. Please complete all fields. You may also upload files to accompany your activity.

You retain all rights to your contributed work and are responsible for referencing other people's work and for obtaining permission to use any copyrighted material within your contribution. By contributing your work to this web site, you give On the Cutting Edge a license for non-commercial distribution of the material, provided that we attribute the material to you.

This form and the file uploads must be completed in a single session. Leaving the page erases the data. You cannot submit a partially completed form and return to it later.

Please note that, after submission, our support staff must do some preparatory work to catalog and post these resources. We hope to make your contributions "live" within one to two weeks of your submission. Thank you in advance for making this contribution!

.

Description

Please provide a short description of your activity or assignment and its outcomes. Be sure to include essential key words or index terms to help users find resources using our search/browse functions. You will find a sample description below.

Sample Description

In this problem set students use electron microprobe analyses of a peridotite partial melting experiment to determine mineral formulas, calculate unit cell content, plot results on a classification diagram, and use a geothermometer. The exercise is especially suited for a spreadsheet like Excel, but can be done by hand. The bulk of the exercise involves data manipulation and simple calculations, but also includes some open-ended questions. The exercise is appropriate for mineralogy or petrology courses. The problem set helps students gain experience with a spreadsheet, manipulate and use quantitative chemical data, investigate the structure of mineral formulas, and see an application of phase equilibria in petrology.

Upload files

We encourage you to upload files with the full activity description or actual assignment, instructor�s notes, and a solution set. You may also upload additional supporting materials such as grading rubrics, data files, images, and sample student work. Individual files should be smaller than 20 Mb. Files larger than this will have long download times that will limit their accessibility. If necessary, put large images in separate files, and compress images to allow for easy downloading.

Please be sure to assign titles to your files that clearly identify their contents and purposes. Please note that your files will be uploaded when you submit this form.

Activity Description/Assignment

A single file containing a complete description of the activity or the actual assignment given to students. Please be sure to include a cover page with at least a title, author(s), affiliation, and contact information. We encourage you to provide relevant background information, context, and goals on the same cover sheet.
