Field Methods for Environmental Sciences Schedule

 

Welcome Picnic

A chance to meet fellow students from ISU and afar

Picnic will occur the Sunday before the course begins, 5-8pm, across the street from campus at 655 South 7th Ave.  Basic food and drink will be provided but you are welcome to bring beverages or additional side dishes.


First Meeting

Orientation and Essential Information

8 am, on the first Monday (DO NOT BE LATE!)—Mandatory meeting in Physical Science Building, Room 220. A light breakfast buffet of bagels, yogurt, fruit, juice, etc. will be provided.

Wrap-up: Goodbyes and departures. We will be done on the final Saturday by 3 pm and provide rides to airports and shuttle services as needed. Remember to add this information to the linked google spreadsheet.


Approximate Course Schedule
