About Our Focus
Our Focus
These are trying times for the environment. With climate change upon us, as well as a host of other concerns, such as population growth, aquatic invasive species, contaminated waters, and loss of natural habitat, the southern Lake Michigan region faces many challenges. Illinois-Indiana Sea Grant (IISG), with its unique mandate to bring the latest science to those who can best use the information, serves a critical role in empowering people to solve problems in sustainable ways.
One of 34 Sea Grant Programs in the U.S., IISG is focused on the southern Lake Michigan region—104 miles of heavily urbanized and industrialized shoreline in Illinois and Indiana. One third of the population of the Great Lakes lives along the shore of Lake Michigan between Milwaukee, Wisconsin and Michigan City, Indiana.
The program is funded through National Oceanic and Atmospheric Administration (NOAA) via the National Sea Grant College Program, as well as the University of Illinois and Purdue University, but IISG also works in partnerships with key organizations, institutions, and agencies in the region to reach more audiences and multiply opportunities for success. IISG brings together scientists, educators, policy makers, community decision makers, outreach specialists, business leaders, and the general public to work towards a healthy environment and economy.

2016 was a big year for Illinois-Indiana Sea Grant! From award-winning work to hands-on field experiences for students, community events on Lake Michigan, and strong partnerships across the region, IISG was busy advancing Great Lakes science, education, and stewardship every step of the way.

Ripple Effects is a collection of 8 activities for grades 6–12 that introduces students to aquatic invasive species in the Great Lakes.
Through research, reporting, and role-playing games, students will:
✅ Explore how non-native species arrived
✅ Understand why they threaten native ecosystems
✅ Investigate their impact on the Great Lakes
Aligned with Next Generation Science Standards and Great Lakes Literacy Principles, this curriculum is perfect for engaging students in real-world science and stewardship.
