ECOLOGY DISRUPTED:  Winter Roads

Winter Roads Make Salty Streams
Show students the Winter Roads Make Salty Streams Science Bulletin to introduce students to the case study. 
Introduction

“This Science Bulletin, Winter Roads Make Salty Streams that we are about to watch is based on the scientific research of Sujay Kaushal. He was interested in understanding if the salt we put on roads to melt snow and ice ends up in streams. We will be exploring the work reported in this Bulletin over the next week or so.”

Questions for Thought

Ask students to write down any questions they have about the research Bulletin.  Collect these questions and after class write the questions on a piece of chart paper that can be easily seen during the course of the unit. 

Note: Refer to these questions throughout the unit and check off any questions that are answered along the way.
